I spent a lot of time and money with all the easy fixes several forums suggested. In the end I had to find an automotive repair shop. AutoMasters listened to everything I had changed and even called me to verify what I had done because electrical problems can be hard to find. In the end, I would've saved a lot of money just taking the vehicle to them in the beginning. I waited a week to do this review to see if it was truly fixed and it is. Runs great and I have no check engine light. Very professional and I would recommend.
