I was very happy to have brought my truck to you for diagnosis and repair. Unfortunately there are 2 more codes which registered in the computer and both of them are down stream O-2 sensors. I will have you shop re-diagnosis the problems after they are installed and check our what ever the computer tells us next. I hope we can find what the problem is and fix it once and for all. I have spent a lot of money at other shops and haven't been able to fix the problems as of yet. Thank you and I will bring it back in and have your mechanics ring it out again!Michael Heindl
