For future viewers with this problem.. Clean throttle body and iac motor. That's a cheap repair and would likely fix it

Mine turned out to be a MAF sensor. It was throwing no cords. Try cleaning the throttle body first. Then use MAF cleaner to see if that helps, which did not on my sensor. I unplugged the MAF sensor and the engine idle changed but did not cut off. So I got a new MAF sensor which corrected the issue.

I would start with the PCV cheapest $3.00, Intake Air Sensor least expensive $20.00, IAC - idle air control, then MAF sensor most expensive. All but the PCV can be removed and cleaned with MAF cleaner allow 30 minutes to dry and then reinstall. Disconnect the battery prior to removing these items. If they are over 10 years old then consider replacing them if the cleaning does not help. MAF clear I'd less than $10 to clean all 3 sensors.

For this engine bad MAF sensors will cause random misfire under load which also probably triggered the MAP sensor. Easy to tell with a scanner which one is bad. Sorry you had to scrap the L36.

did you change the IAC valve with no luck ??

I have the same problem intermittently was this a constant problem for you or on and off ?

A I have a 2000 grand prix gt... Dat runs but soons u push the gas it turns off ... I jus trying to figure out how to fix it... Don't know dat much about cars

Before you change the map sensor replace the PVC valve under it 5 dollar part no tools needed trust me

Did you try a new fuel pressure regulator?

What device did you use to get the codes?

So what fixed it? Never mind I saw you scrapped the car. Bummer it was probably a simple fix. Thanks for sharing. Best Wishes & Blessings. Keith Noneya

I put diesel in my gas tank it's the same engine 3.8 I had gas tank dropped and I I'm having problems with it turning over now

Exactly what was the purpose of this video ?

Any luck fixing this? what was the issue?

did u ever figure out the problem? i have a 2000 ls with the 3800 and im going thru this right now... the car turns over when it feels like it... most of the time it'll start then immediately shut down

it was the maf sensor the car isnt going to idle with out the maf sensor.. pointless video waste of a good engine.
