Got a hesitation issue after a pull off from a stop it does it on and off, but now its doing it more often. Only codes were knock sensor and 02 sensor. It does it whether its cold or hot. Now check engine light has gone off but it still does it. I tried adjusting the throttle cable but still same problem. It starts right up and idles like it should. How do i check the coils? I also havent changed spark plugs and i pulled the rear coils out to see if they had oil on them because the rear vcg is leaking, but all three were dry.

Got almost the same issue like yours, replaced MAF sensor and knock sensor, replaced front left O2 sensor, still hesitation pulling from stop, CEL remains off. Hot engine is worse.

graff_hip_hop

try cheking the egr system may be getting stuck

mmgio

to the op.If it hesitates right after you start it from cold it probably isn't your o2 sensor.They come in to play when the car reaches normal operating temp.You may have a bad injector or a coil acting up.With intermittent coil problems it's very hard to tell.The resistance check doesn't always work.This is a tough one.You could try buying 1 used coil and swap one by one and see if it fixes it although the front and rear coils are different or maybe do a resistance check on your injectors.

thanks man I bought new spark plugs today and installed them, and I noticed that one of the front bank coils had a peice of tie strap around it, Im thinking that it may be my problem coil. After spark plugs were installed i did washer pump, and tie rod end. kind still hesitates on and off not all the time, but shes got more get up and go now after the new spark plugs lol! Tightening up the throttle cable helps out alot too. I will grab a junkyard coil in the morning to see if that solves it.

Check the TSB. There was a problem with the diffeential shaft that caused this hesitation.

maxinout93

Would that b the cv joint? Would. Nissan still honor or recommed a solution to fix it on a car this old?

They can do it but it wasn't a recall. Here is the link to the TSB I was referring to. See if it applies to you.

your problem likely has nothing to do with your throttle cable, so definitely stop messing with that.

maxinout93

I dont kno sometimes it does it and sometimes it will speed up great. Its not a bad hesitation and it doesent affect high speed driving at all. I use mostly regular gas and cv axles appear to b bad. So i dont kno if that has anything to do with it. My check engine light just came on so im going to pull the codes and report back tomarro

Not trying to hijack this post, but i also have a hesitation problem and a stalling problem, its been going on for like a month now and I've tried a bunch of different things. The codes that came up were both o2 sensors, MAF sensor and knock sensor. Ive replaced both o2 sensors and swapped out the MAF sensor and neither of those stopped those codes from coming up. I replaced the fuel filter, ran fuel injector cleaner, started running 93 octane fuel, and the stalling still persists. The stalling and hesitation started a few weeks after i installed this crappy $30 ebay short ram intake which I'm speculating is the culprit. It has a crappy filter on it and it doesn't even fit well i have to bend it a certain way so it doesn't hit the battery. I ordered a Weapon-r secret weapon intake that should be here friday and I'm just hoping this will solve my issue. also it smells like fuel when it hesitates and when i give it gas its very slow to increase in RPM's. I don't understand why this stalling problem is occurring and its been bothering me badly. Im curious to hear what others have to say

The bolded item is your culprit there. Scan for codes and see if you have P0325 stored. If so, you need to get a new knock sensor.

BostonBarrett475

The knock sensor can cause these symptoms? cause my knock sensor code keeps coming up when I personally reset the ECU, i just figured it was a ghost code cause the MAF, and both o2 sensor codes were setting off too but maybe your right

maxinout93

Got a code 0304 for knock sensor, and 0707 for rear 02 sensor.

What happens when you are at a light and you are in drive with the A/C running? Any stumbling or missing?

Mine did that for 2 years before finally kicking a P0305 Missing 5th Cylinder Code today. I need a new coil pack at the rear of the engine closest to the driver's corner.

If you have these symptoms, could be the same. Mine always got worse when it was HOT and terrible with the A/C. When I accelerated, it wasn't as noticeable, but the car didn't pull like I remember.

I hope this helps!

rhonster

a little dose of SeaFoam will clean the fuel path and injectors so you can atleast rule out that problem.

maxinout93

No my car doesnt have any issues with the ac running. It idles great and doesnt stumble. I notice it while trying to accelerate quickly it hesitates a little. It may b a coil but which one i dont kno? I may get sum oe from the jy and switch them out to see if it resolves the issue.

rhonster

the ks code may go away with a new sensor, but a new ks wouldn't hurt although neither are at the root of your problem. I can get you 6 decent albeit used coils for $100, you pick the shipping method and added cost.

Again, a tin of SeaFoam will last quite a while and does a bang up job cleaning with no residual issues (like burning out o2s). A couple ounces every 3 months or so.

My throttle cable had a 1 inch slack tightened it up this weekend and the car diff. Feels quicker. Better response when you hit the gas.

Before you start changing parts, clean the EGR tube and valves, check for any blockage in all the hoses, clean everything the best you can, and replaces hoses as required. It is maintenance, so even if that's not the source of the hessitation, it wouldn't hurt...On my case, I get rid of the hessitation on my 98 5spd SE.

Good luck!

maxinout93

Ok i will try that before i change the coils.

Found the source of my hesitation issue. Cylinder 5 had oil on the coil and the plug, so obviously my spark plug tube seals are leaking there as well as valve cover is. Leaking.

rhonster

I've had a plug electrode covered in oil after a coil expired (#2), but to have oil seeping back up into the plug cavity itself is pretty weird. Where was the "oil on the coil" coming from?

maxinout93

The oil on my #5 coil was at the bottom of the boot. The lower part of the spark plug was soaked in oil, as well as the bottom end of my spark plug socket. I had no idea it was doing that. The car was running good with all that going on!! Im assuming the spark plug tube seal on that cylinder is bad. Looks like ill hav to remove the intake and replace the valve cover gasket and tube seals. I hope removing the intake on this car isnt as long as removing it on the 3rd gen vg engine.

graff hip hop is right check the egr valve but before you go crazy plug your scanner check the codes. Also check the mass air flow sensor. if there is a check engine light check it see what codes you come up with then take it from there. first thing check the codes. i have the same issue with my 95 maxima one code wasthe mass air flow but there is also a intake air temperature sensor which can cause hesitation and your EGR valve as well.

maxinout93

you are right, I got a code for the intake air temp sensor, anybody got an idea of how much one costs? I already ordered a new knock sensor. I will check the codes to see what else pops up.

blackcloud80

oh yeah the intake air temperature sensor is $40 bucks at your local autozone its right on the intake box next to the mass air i believe.

blackcloud80

definitely change or clean your egr valve as well could have carbon build up p0110 is the intake air temperature sensor code p1400 is the EGR code but on the scanner doesnt say egr looked it up in the haynes manual and thats the identification code.

Rob_0126

Did replacing the air temp sensor do the trick?

I think your problem is a failed coil. I use to have that problem until I found the bad coil and replaced it. Problem solved. U should try to pull your coils n cleaned them. Then check the ohms. The really off one should be the bad one. I don't think the air temp sensor would cause the problem. I have no air temp sensor hooked up and I have a check engine light on for it and my car runs like a champ still. But gl.

blackcloud80

had a problem with my egr valve today seems the tube going into the egr is seized they are not moving at all im thinking this could be the problem towards my hesitation issue. cleary this thing never been changed any how im a cut the tube then replace it with a new one less headaches

blackcloud80

As far as the air intake sensor have to get it from the dealer Nissan

replace the knock sensor sometime there a code but no CEL....check your TPS setting at idle and WOT the manual teel you the required setup....if this is off it will directly affect your throttle response.....Clear all your CEL's and pull all your coilpack and plugs clean and seal coilpack tips with dielectric grease....and reinstall

Rob_0126

What exactly are the symptoms of this? btw isnt there a writeup on doing this?

maxinout93

well I got a new knock sensor, and a new iat sensor. the car drives a lot better, much better throttle response. but now car has a miss which may have to do with the hesitation issue. would pull the manifold off myself and change out the fuel injector but can't seem to get the screw to turn near the ps pressure hose. gonna take it to a mechanic.

Hi, I have that kind of problem those days but way WORST.

I can't it the pedal, maybe around 45% of the throtle, the engine hesitate. I cant start in 1st speed. The car react exactly like a brand new stander driver!!!

the car start shaking like crazy. It looks like it missing gas. Really dangerous since I cant do heavy acceleration on highway.

I changed fuel filter and clean the tb. Immediatly the problem was gone. A week after is back and worst...

My guess is the fuel system.

oVeRdOsE

Well I think I found the source of my problem....

New injectors...

maxinout93

wow is that your fuel filter? I may need to change mine. I want the 300zx filter though. thank goodness only one of my injectors are bad!

Rob_0126

wow. how long has it been since you changed the filter?

To anyone who knows: How good are the 300zx fuel filters and their longevity?
