so your car runs like crap but if you let it cool down it "fixes itself"
you have a code set for an o2 heater circuit malfunction
did you address that problem yet?

Camarokid08731 12-13-2008 05:53 PM

no i havent yet but the 02 circuit wouldn't make me loose my tach signal but ill have more info in about an hour on the issue im currently under the car on my sidekick

id be willing to bet its the crank sensor. after awhile sensors get old and a common occurance of a crank sensor going bad is seemingly random stall outs and ignition problems. once an old crank sensor gets hot it ''blacks out'' and loses functionality until it cools back down again and ''wakes up.''

Ok i fixed it turns out that when i installed the headers a few months back the harness for the crank positon was next to the header. the header melted the harness. so i re wired my harness cut out the bad section and re wired it. then wraped it in heat resistant tape.

told you it had to do with the headers.

they absoultly suck on these cars.

Put some new O2 sensors in the car as well. If you had to hit the sensors hard to break them loose from the manifolds you most likely damaged them. And if they're the originals with 90K miles they should be replaced anyway.
