Pontiac Problems? Ask a Mechanic for Answers ASAP
Welcome I'm Chris aka Moose
PIC 4343B is a NHTSA number not a GM number so it was impossible for me to cross reference that number through the repair guides. The only TSB that comes up involving code P1125 is the one below, is that what your asking for?
-----------About me and Just Answer------------
I am in my upper 30's, have a wife and 2 sons. I farm, fish, hunt, build, and coach youth soccer. I work on anything with an engine, been to many schools and classes through my 12 years with the dealership to get trained and certified. I try the best I can to share what I know and or have access to with my customers. Please consider I base my questions and answers to you, solely on the information you give me since I am not there to see, smell, hear, touch, or test. I try my best to be here everyday starting at 3pm central. Rating an answer is required. Please let me know if your not pleased prior to rating or if you cannot rate me so I can try to help a different way. God Bless and have a great day.
Sorry you were not pleased. I can only look up the TSBs by the number GM uses not from the national highway traffic association.
