Thread: Car died in traffic, won't stay running.

Step one complete! Disconnected the MAF sensor, drove the 4 mile back home, and swapped out the MAF sensor from my Impala. Going to test it by driving to a friend's house about 20 miles away. If I may it back, I'll call it a success.

I'd say problem solved, until I get the replacement. Just put about 45 miles on the moved MAF sensor, no problems. Now just have to wait for a replacement! Thanks for all the help. Next time the car dies, I'll just have it towed to my house instead!

Ed Morad was out of parts, so I went to Greenleaf Auto Recyclers. They had the same part for cheaper, and offer a 6 month warranty standard. Just saying they might be an option, too.

I have an ODB II reader, but since I replaced the MAF sensor, no trouble. I'll hook it up and see if there is anything. I'll clear it if so.

And correct me if I'm wrong, but if you get a code, then fix the problem, the code will clear itself. I did some engine work and got two spark plug cables swapped. Check Engine light came on, of course. After switching the cables correctly, light went out. So even if a "hidden" code was thrown, I would think it would be gone now, since the car has been running fine for a week.

I knew it cleared itself somehow. There's at least 2 cycles a day for me, and I did some driving last weekend, so I'm at least halfway there now, if not more!

Sounds like one of the programmed "Mr Goodwrench" zombies...

I'm pretty sure all MAF codes set a CEL. I could always go open up the PCM file in my tuner and see which ones do and which ones don't.

No code, just checked.

WHAT?? WHY?? ARE YOU HIGH??

a tech 2 is a great tool, however for simple code stuff any OBD 2 code reader will work , and google if you need to personally i use ALLDATA and a snap on MODIS

PS - im a GM tech CERTIFIED
