I went to start my car after the doctors this morning, and it immediately threw a code 34 "MAF low" and pegged the BLM's at 156. If I let the car idel it would idle fine, then randomly almost stall and cough back to life after a few seconds. There was a strong "running rich " odor at idle. I datalogged on the drive home... for the most part it seemed to run alright, but the BLM's remained pegged at 156 unless I was at WOT in which case they would drop to about 140.

Shut the car off, turned it back on, seemd to be gone.

What do you think happened?

 

TTT
What would cause such horrible blms

 

i got a prob like that too but it wont seem to go away as long as my car is moveing it runns good but if its not moveing it idles down around 500 rpm and either stalls or brings the rpm over 1100 and i just replaced my ignition module!
