Hi. My name is john.
I just bought a 2005 Pontiac Grand Prix base. It has lots of add ons including an engine swap. It wont pass inspection because of the check engine light. Everything is triggering it.
The previous owner did all the work or at least paid for it. My mechanic needs me to find out what kit was used to convert the engine. I cant find that info. What can i do to save myself thousands in labor to have him go through the car and possibly try to fix it blind? Please help me, lol. I appreciate you reading this. Hope you can help. Thanks
Just wanted to add that it is a V6 Supercharged. Not sure the origin or year of the engine. My mechanic wants kit info to get a manual to follow the conversion kit process and try to find where the conversion went wrong. The electrical is where the problem is. Car runs and drives fine.
