Well, at first I thought we found the problem of why my car was running bad:
thats the first o2 sensor... caked with carbon. heated it up with a torch to clean it. im not sure if it was heated enough though. anyways, even worse:
We figured it must be shorting out and causing my car to run like crap, and causing my spark plugs to look like this:
It seemed like the problem was fixed after we cleaned the o2 sensor and put electrical tape around the wire with exposed metal, and completely re wrapped it. But after driving for about a half hour, the car started running bad again.
Im not sure if this has anything to do with it, but before, I remember my car would always get to 190 degrees. Now, my car never gets to 190, its always between 175-180. What is normal? Could it have anything to do with my car running like shit?
