I have a 2000 Pontiac Grand Prix that dies while driving and the steering wheel locks. The problem seems to be getting worse. It has done it for quite some time, been to the shop a few times, some ERG thing replaced (unauthorized) and it still does it! please help. I had seen the same problem posted and a previous article about a tachometer disengaging. I haven't been able to find the full chain to read. thank you

I tried to call the shop. I had to leave a voicemail. The invoice reflects Mass Air Flow Sensor R & R, MAF Sensor, Note: M - Labor Database, Copyright Mitchell International, All rights reserved. The check engine light is not on

if you had a mass air flow fault code , while the car is running , if you unplug the mass airflow sensor the engine idle should change ,if it doesn't ,it means sensor not working or no power to it .

1- check all fuses first ,check the air breather hose is attached correctly from air box to throtle body and no air leaks

2- try to get me those fault code if possible , i will be online all day, if you get them,just post them back here and we can continue

i m online all day till 12 tonight

Will do. I knew that shop visit did me no good. He did the work without my authorization and just ran with the error code. This was back in Dec 2012 and the problem remains. To be continued.
