I have a 2001 Nissan sentra which will barely idle and will reluctantly drive and not go over 2500 rpm. It has been diagnosed through the scanner (codes) with needing a MAF sensor. I am just wondering if anyone has any related info regarding this problem??? There seems to be a history of this situation after doing some quick searches. ---

You might try to clean the MAF sensor with some sensor safe cleaner. I used brake clean the last time I cleaned one of mine, it fixed my problem, (CEL), however I don’t think it is probably “sensor safe”. Cleaning is a lot cheaper than replacing the sensor, and oftentimes works. ---

Thanks we did try cleaning it and still get the same problem. ---

So much for that idea, (cleaning). Ok then. Many times when you cannot rev the engine very high, it is a clogged cat. I don’t honestly know if a bad MAF sensor will limit the RPM? It might, I just don’t know. Someone else might come on and answer that question. If you recently had a dead hole, where a cylinder wasn’t firing, I’d suspect a plugged cat. Otherwise, maybe bad MaF? ---

ok so back again I am - Changed MAF reset code 100 - instantly trips same code and car will idle fine but will hesitate and bog above 2000 rpm… any other ideas???I would greatly appreciate it…
