Hey guys,

this time I really need your guys' help. So here is what my set up is:
Its pretty much stock except for a short ram intake with the MAF sensor kinda wired next to the filter cone. other than that, my engine is stock. Replaced oil(2 weeks ago) and sparks(a year ago) routinly. Im not throwing nay codes and have replaced the knock sensor already.

So here is the issue:
over the last 3 months my car has been falling low in the rpms(300-500) when pushing in the cluth after steady acceleration or cruising) but then it bounces back. starting idle is around 1100-1500 after starting(takes 3-4 cranks to start) Then yesterday, after driving fine, the car started bucking like crazy, and it felt like the engine was gonna die out. Pushing the clutch back in would set the rpms back to 600-ish. When in neutral and revving, the car seemed like it wasn't getting enough gas and would die out. Seems like its not getting enough gas.


So yeah, please let me know what I can do. Much appreciated

check your MAF sensor. i have an auto but when mines was bad it wasnt throwing any codes but that def was the problem. check it asap

This reeks of a MAF issue. Especially since you've been pokin around there. If it's not reading the proper amount of air, it's not going to deliver the correct amount of fuel.

I cleaned the MAF sensor with maf cleaner and also scrubbed out the TB with throttle body cleaner. So far its been a lot better, but it comes back from time to time. Say after 10-15 minutes of driving. Now it only happens in 1,2, and 3rd gear. Starting in 1st gives me those old sputtering issues, so I have to go into 2nd really quick.

Does this mean my MAF is so crapped out that I need to replace it? Let me know guys.

btw, I have done all my research on these forums but nothing really applies to what i am experiencing

Sputtering... Could that be shaking the car? Like as if the engine is moving... Sounds like what I have to do...

rizzindriver89

No sputtering as in bucking back and forth, as if its not getting enoguh gas. Its drivable now, but it still does it in 1st and 2nd. So I'm really on the fence of just buying a new maf and a new tps.

any input?

Does the problem stop if you disengage (pedal in) the clutch?

rizzindriver89

So i figured out what the stuterring issue is, everyone with these bucking, stalling, surging, and crappy idleing problems:

Its most likely your IAT sensor. The little one that looks liek it does nothing, yup that one! After replacing maf and tps sensors, cleaning throttlebody and iacv, and testing coil packs, injectors and checking spark plugs, my car finally decided to throw me a code: IAT failure!

Replace it asap and your problems will go away!

good luck

yeah you go ahead and replace it and let us know how that goes

I wouldnt bother with the IAT. Check the TPS but dont count on the specs to tell-all. I'd get a used front and rear coil from the classifieds to swap out and diagnose. You can always re-sell them if none turn out to be bad. I replaced my TPS with new but have quite a few used ones I would swap out to diagnose with if you are interested. I think I have 3, I dont think there was anything wrong with any of them but since I can't guarantee any of it I'd be willing to sell them to you for cheap. LMK!

I don't see why there would be anything wrong with an aftermarket coil. I bought brand new from an ebay dealer and payed like 300 bucks one time but now I think id just buy used or aftermarket.

i bought my 95 se in october 09. lots of issues are you are describing. i was told MAF sensor, injectors, etc etc... well, not having much of a budget, i decided to throw some fuel injector cleaner (fuel additive) on top of premium 92+ fuel each and every time and my problem has been completely eliminated. its been good since the end of october. this may not fix your issue, but it seems to have fixed mine =)

mrfliboi

i have to clean my maf and throttle body also.. im havin a similar problem

rizzindriver89

Ok, so its been about 2 months now and my problems have completley dissapeared since I replaced my MAF and IAT sensor. They seemed to be the culprit snce the car runs beautifull now. Chillin, im not saying that the IAT played a major role, but if its sending a funky signal to the ecu, it might reatard the timing, fuel mixture etc.

I did not however, replace one and then the other so I will never know who was doing the most damage.

On a side note, mrfliboi, I tried cleaning both with little effect. It will help for a couple of days, but once the engine gets really warm itwill come back. If u need a MAF sensor, I have a spare one since I bought one too many.(its not the broken one though lol, that one was thrown in the trash with much enthusiasm

autozone sells MAFs now....which is quite dope if i might add hehe

YEs the resistance of each coil shd be within spec. If they were all over the place then most likely they have gone bad. Get coils from a 98 max as i have hrd the earlier model coils were WAY more reliable than the 99's

Seems like and air issue to me. Any codes? Did u replace the IAT with new.

THe MAF is going bad if RPMS dont rise above 2400
