UTEC failing... check proper grounding otherwise swap UTECs.

 

I ran a diagnostic test again and now I have a P0442 code which is a small EVAP emisssion control leak along with my P0037 code which is my bank 1 downstream O2 sensor. I tightened my gas cap just in case. So if it comes up again this weekend then I'll have to figure that out as well. I was thinking maybe it could be my fuel filter but probably not since the issue goes away after a couple minutes of driving. So heres the list:
1) UTEC is bad
2) Spark plugs are burnt to s**t
3) fuel problem i.e. fuel filter/pump

I'm going to take the picture of some of the spark plugs this weekend and post them. Most likely I'm just going to replace them.

Has anyone had a problem with a HALTECH going bad on them like the UTEC has done for many others?

 

Bad 02 sensors cause all kinds of issues, get that fixed. You should replace the plugs, but still post pics so we can see what's going on. Also we don't have fuel filters... it's a sock around the fuel pump basically...

 

well im trying to upload the pictures on here but it's not letting me. Something wrong with the website.

 

well there we go. I took a picture of all of them but these are two difference plugs I believe and they are the worst of them that I noticed. The rest of them are still burnt but not as bad as these. Thoughts? I was also wondering if I had to retune my car if I got 2step colder plugs. Wouldn't it be harder to start my car with 2 step colder but in return perform better than these 1 step colder plugs?
