I went to the beach in my truck the past weekend and had some fun on the sand w/ my truck (of course) but when I hopped back in it the next day my service engine soon light was on, been on ever sense. I looked around for a while and found that I have a missing header bolt, I knew I heard an exhaust leak! Anyways, I that whats making that Service engine soon light come on?
Thanks for yalls help.

 

A exhaust leak could definately be your problem. It can cause the O2 sensors to show a lean condition. Get another bolt in there. After several driving cycles the code will go away if that was the problem.

 

Thanks a lot, getting a new bolt will be a lot faster than getting a diognostics check!

Thanks again.
