2008 Pontiac Grand Prix 3809 series 3 stalling
To make a long story short a couple months ago i replaced the crank and cam sensor then finaly resolved a similar feeling issue by replacing the ICM. There are two large threads on here about that work if you want to refer. After the ICM was changed the car worked great for about a month maybe two. Then it started sputtering yesterday very much like what happend before then it stopped and wouldnt start yesterday. It turned over but wouldnt start. I met my daughter today to look at it. When I started it it started fine but stalled 30 secondd later. I jossled the wire harness to the icm and strated it again then proceeded to drive it home while my daughter followed me. It stalled several times om the 20 minutes ride home where I never went over 25 mph. It didnt seem to have power at times and could stall at any moment but luckly i made it home. I thought for sure the icm was bad again bc it felt the same. I put the scan tool on and i got different codes this time. I will post scrren shots. On a side note she has developed a leak in her exhaust system someplace bc its a little loud not to bad.

Its a different code then i had last time though. https://cimg0.ibsrv.net/gimg/www.gmf...f73dc6f8de.jpg |
i was surprised by all of the codes except p 1350 so im not sure if they are related to the stalling issue or if they are just other issues that happen to be comming up.
|
I have a life time warranty on the icm from AZ so I may just swap it since its quick and easy.
|
Some other screens for the scanner that looked high
|
Any thoughts. Clearly the engine is the 3800 v6 series 3.
I had a typo in the title of myoriginal post. Car sometimes will crank with no start, after a while maybe a day it eill start but stalls and has no power and eventualy willcrank with no start for a while.

I took out the duralast ICM and swapped it for a new one and it has ran fine for the two test rides I did. |

Im not an expert on that but i did ensure i had good ground atbthe harness going into the icm and i removed, cleaned the bolt for the ground thatbis mounted to the frame.

Its been running fine for about a week and all I did was swap oit the ixm again. Is something else causing the icm ro fo bad or was it just a poor paer. The first one lastsd one to two months before it dies.
Thanks |
Not sure I understand this part:
