hesitation

Recently I noticed that my car has a hesitation to accelerate at WOT. I also noticed a power loss, what could this be from?

Knock Sensor
Fuel Filter
Air Filter
Spark Plugs
Tune up time perhaps?

Might be auto lag... If your car has to downshift to accelerate, there'd definitely be a delay/hesitation while it figured out it needed to downshift and then did it.

I have the same problem. I did a full tuneup, but it's still there. I'm missing a hose clamp where the MAF connects to the resonator so I know I have a small air leak.

I'm going to try and clean the MAF sensor with rubbing alcohol and I'll replace the O2 sensors soon. Need to get an intake and y-pipe

Can I do all of this? MY car is starting to have a lot of probs including alignment and maybe wheel balancing and was wondering if maybe I shoudl take it in to ahve it checked out? Also on the injen CAI there's a black hose that doens't connect to anything. Is that supposed to be like that?

u can do all that stuff yourself and save a few bucks, but the fuel filter is a pain in the *** cuz its in the back along the firewall. also I think the hose is a crankcase vent, or a vent for something. all maximas have that

Forgot to check the signature box, but I got an auto

My mom can't drive a stick so she needs an auto, so I have an auto so she can drive my car to work if something happens to her car. My car is the family "backup" car

Plus, no one to teach me a stick

One of my uncles will come here in a few months and I'll probably get a 5-spd beater so he can teach me

The tuneup is easy, I did it a few weeks back. Just remove the whole intake thing (like when you're cleaning the TB) to give you enough room. Clean the TB and IACV while you're at it

Your right about that. My hands were bloody after changing that stupid filter.

what about the egrc solenoid valve?

it's right around where the knock sensor is... it has 3 hoses coming out from it...

when mine was connected badly it threw a code and i was getting incredible lag... I had NO power at all at all... i swear i lost 20hp just from that!

The fuel filter is a 5min job. Just remove it from the clips by pulling it. Now you have room enough to even put it upside down...

I get tired of people jumping all over some one because they didn't search 1st.If you don't want to help someone out then just ignore the thread, It's that simple. Could the problem with the hesitation be because you switched to lower octane gas?I know a lot of people have done that since gas prices went up.I had a 3rd Gen. that I tried to use lower octane gas in for a while and it hesitated like crazy in 1st and 2nd gear.Just thought that might be a simple fix.

Easiest way to learn is to do burnouts......

Then, just use less and less gas and clutch until you have a nice smooth start. Best done in a $35 a day rental car. P.S. Get the $5 a day insurance too.

lol thanks for the tips! Let the rental company worry about a clutch messing up

I guess I'll do that

Oh the sig, well I didn't reword it. Kevin banned my account for a couple days and deleted the sig. This is the 5th+ time people got ****ed because they didn't realize it was a sig...

I'm having these problems too! Please help! I have a 99 ES Max with 85K (km's, I'm Canadian) on it. There's hesitation under WOT all the way but especially past 4K RPM's. It's awful. I have replaced a bad ignition coil, all the others have been tested and they're fine (even stealership said that and its not under warranty anymore) I've changed my spark plugs to NGK Iridiums, BKR5E-11 or something, it was the proper ones. I've replaced my fuel filter, my air filter is ok too. Car is completely stock. What is this problem???

stephen. just do a regular tune up, fuel filter, get only super gas like i did when i owned the car, and the injen cai is supposed to have the tube exposed. it is to let extra air that is sitting in the top out. it is like an air blow off valve. i put it in, so i know. if you still dont believe me, look in the directions inside the box with the stock intake parts in it. the injen directions are in that box. peace Vinny

Thanks. I'll do the TB cleaning soon and diagnostics too. I just checked my KS via instructions posted elsewhere on the .org and its fine, I think. Reading around 562 ohms. Hopefully its just the TB, cause that KS is going to be a major pain to replace.

It could be as simple as buying a higher octane gas, it was for me. That took care of my hesitation.

yeah, I'm afraid it isn't that, I regularly run 91+. I've only once filled with 87 by mistake. Ah well. Its cold here, I really don't want to go outside to rip off the TB, I need a warm garage.
