ok i said a few days back, thatmy cat was glowing red and ideling really rough, well i gutted my cat, and it runs a lil better, theres nomore glowing, but its still ideling bad, its kinda ideling low, and it kinda acts like its missfiring a lil bit, and i can deff tell its lost power... does anyone know whats going on?

 

sparkplugs ( could not be gapped right or need new ones ) could be crosswired. check to see if the gasket is leaking. tighten up exhaust bolts. check all the basics first.

 

ok ill do that, but someone tld me that gutting my cat will mess up my O2 sensors and my car will never run right again, this isnt true is it?

 

No it won't. The only O2 sensors that have to do with how your car runs have nothing to with emissions or the cat. The O2 sensor after the cat will be upset and throw a code, but that is it.

 

oh ok, but does anyone know about my first question? oh another thing, my car shakes more now, the hood and everything

 

how old are your spark plug wires? they could be arc-ing if they are old and have small cracks. if you have not changed them very recently then do this....
either wait till night/dark out or open the hood and cover it with a blanket so you leaning in to engine compartment is dark, then start the car and take a spray bottle with water in it and spray all off your spark plug wires... if they are bad and arc-ing then you should see little blue flashes and if so, get some new wires and be sure to wire them correctly and run the wires so they are not touching anything hot!
