• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

P0335

I have a 2008 Grand prix with the n/a 3800, I keep getting a code for p0335. It mostly happens when warm, first start of the day car runs good no codes but if I shut it off when it is warm and try to start it, it starts hard usually 3-4 tries. I have put a crank position sensor and checked the wiring for continuity and damage, everything looks good. Pulled the igtion module off and made sure everything was clean. I am looking at replacing the module but hate to spend the money if it is not the problem
