I am having a problem with my car. The problem is that when I am driving it, all of a sudden it wont accelerate. It just idles. Sometimes it will kick back in after a little while. Other times I have pulled over. In those cases I rev it couple of times on Park. Then sometimes it kicks in and sometimes it doesnt. Can anyone give me some help to maybe get an idea of what it may be? Also the check engine doesnt go on either. Thanks for any help in advance.

 

it sounds like a maf problem. Does the car not wanna go above 2k rpms? maf problems seem to be the thing with our cars.

No it wont go over 2k rpms

 

Yeah, this most definately sounds like a typical MAF failure.

Check here for more information.

 

Before you do too much, I would suggest cleaning the MAF.

I have decided to add this to the list of periodic maintainance for bothof my cars as it does seem to help dramatically. It takes some time to get the Maxim MAF out (you have to remove the entire airbox), but once out it is a pretty easy job.

 

I would agree with Jeff. Just get some CRC MAF cleaner (most autostores have it) and see if that helps before you drop the money on a new MAF. Also on the new one remember to do regualr mantiance on you MAF since you know they are weak.

 

My 2k SE 5sp is approching 100k mi and beginnig to fall all apart.
A SES light several mo ago prompted a normally reliable shop to read a d0430 code and replace all bank 2 coils and all 6 plugs. That left my car with no SES light but a stutter and crappy performance. After having it in 2 drealers who wanted to( and did) adjust the A/F mixture, the problem never got better, only worse. No SES light, but a huge drop in accel. at 3500rpm.
Reading Max.Org, I myself decided to replace the MAF myself which eliminated most if not all of the performance problems.
But the SES light came back on with a 0430 code.
Dealer #2 again suggested a new B2 O2 sensor, which worked for 60 miles to only throw another 0430 whic prompeted them again to adjust the A/F idle mixture. Again, worked for 60 miles and now the SES is on again.
They DID NOT reprogram the ECU citing it was not reccommeded for MY car which is fed spec 2000 5 sp.

NOW WHAT? Does the MAX turn to junk at 100k?

I ask becuse simultaneously I have a stuck emergency brake thats burning out my new rear pass. rotor. ???

HELP ANYONE?

 

hate to tell you this... but this is all minor stuff... you could have some engine internals mess up, now that would be something worth really fussing about.

Get an O2 sim, your cats are probably bad.

 

Thanks Chopstx

I really like the car, when it’s running properly and have incentive to hang on to it since it’s paid for. Minor modifications and additions have it just right for me now, but I liked it better when it was in warranty.

Pls explain 02 Sim? I have considered the cat being bad, but the codes dont point there.

Although everything read( including the short instructions on the box from Nissan) says reprogram the ECU after replacing a MAF. The dealer refuses it as a solution, but says the "codes have been cleared and that’s all that it needs"

Should the ECU be reprogrammed, not just resetting the sensor?

Since NO dealer even suggested the MAF as a potential source of the crappy
performance, obviously, they remain suspect idiots in my book.

What’s the REAL story?

 

I already cleaned the maf, and still no help. I think I may just have to change my MAF. Thanks for the help everyone.


P.S. not to be a jerk, but next time start your own thread when you have a problem. Its not good to highjack someone elses.

 

Sorry to hear that about you anskyruben. Be sure to hit Dave b up for a new MAF he will give you the best deal check the stickes for his contact info and remember to still do reg mantience on the new maf. In fact there are some writeups here on converting to a A33 MAF which is strong if I remember correctly. Some of the vets step in to confirm.

 

Yeah, I had the same issue and went with the 2001 Maf when the one in my 2k2 took a pOOp. The only problem is that it will throw a code and you will have to drive around with your ses light on.

 

If you use a 2k1 MAF on an 02-03, in order to get rid of the CEL, just transfer the IAT thermistor from the 02-03 MAF and connect it to the 01 MAF. There is a write-up in the Stickies if anyone needs more details.

 

Thanks for the confirmation guys. Good luck on the install.
