2006 Grand Prix stalling issues

**Cutler06** · 07-07-2012

I've replaced the pedal sensor and swapped the throttle body, same problem. I'm all out of options other than wiring and ECM. I'm trying not to take it to the dealer. I need all the help I can get! Thanks.

Have you checked the CAT converter. A bad or plugged converter can cause stalling, mine did.

What exactally is it doing? Stalling could be caused by anything from a bad sensor to problems in your transmission

More info on what exactly the car is doing.

When does it stall, where in your drive period?

As just a guess, the crank sensor is a known cause for random stalling.

Won't rev with brake and gas applied at same time. 0-20 mph pedal has to be on the floor to move, won't go over 75 mph

sounds like a clogged cat, if you try to drive it at night, the cat will be glowing red in no time if its that clogged.

Could be a bad MAF

You can also check the cat conv. with a infared temp gun if you have one or can borrow one from someone. You have to wait until the engine is at opperating temperature and then check the temp right before and after the cat. It should read cooler on the inlet side and hotter on the outlet. If it is the same then the converter is not working but is not clogged either. If it is higher on the inlet side and lower on the outlet side then it is clogged.
