Code p0172 on my 2002 buick lasabre

Question

Car starts good the 1st time you start it, after that, when it is warm, it stalls every time. Have to give it gas to keep it running. I also hear a rushing of air, when it goes away, car seems to run then.

Answer 1

check for a intake leak, also try to clean the mass air flow sensor with mass air flow sensor cleaner, or maybe the throttle body is dirty try to clean that also.

 

Possible causes

- Faulty front heated oxygen sensor
- Ignition misfiring
- Faulty fuel injectors
- Exhaust gas leaks
- Incorrect fuel pressure
- Faulty Mass Air Flow (MAF) sensor
