Post by: sidekick101 on February 24, 2007, 09:43:43 PM

i need to get a new o2 sensore for sure because the threads are gone and it popin out. but  i went to put it back in tonihgt and the manifold was glowing red. i knwo thats not normall. i check the back and shes blowing out fine? any ideas? would a new manifold/ header get rid of this or would i just write a header off if i bolted a new one on. HELP!!! please

If your not running it hard up a hill it's running lean, look for vac. leaks or a bad egr valve or your sucking air into the exhaust some how or your down pipe collapsed inside or your cat could be plugged ect.

i don't think its a plugged cat because it still flows fine out the back. but the o2 sensor does fall out so maby thats making it heat more then normal?
