I have a 95 automatic, which has been given me nothing but trouble for the past few months. Now the car stalls when I stop for a stop sign or get stuck in traffic. It seems to be doing that less frequently when I have the AC not running. In addition, the car hesitates or “jerks” at high speeds. I pulled off two codes for a Knock and Mass Air Flow sensors. My question is: can a faulty Knock and MAFS sensors cause the problems I described above? Please help.

yes. read the faq's.

 

bad knock sensor could cause the bad performance but not stalling. also even if u disconnect the maf the car will still run. just wont rev pass 3k i believe. check ur maf voltage. read the faq about how to check the maf if its bad.

 

This is a long shot, but I once has similar syptoms and it turned out that I needed a new muffler...good luck.

 

It's the MAF, I ahd the same probs recently. Sucks ha? If you ever get stranded, just unplug the MAF, and you can make it home, can't go over 2.5k though.

 

Empy fuel tank can cause similar problems too

 

Thanks guys. Will change the MAFS and see what happens.

 

same exact thing happened to me, i havent fixed it yet, i just let my car warm up for 10 minutes and it runs fine... the only reason i havent fixed it is cuz im on vacation right now.
