my idle is really erratic and i have a bad exhaust leak. change my cat. today and still it stinks. i notice the idle got worst after a tune up, yes after. (oil change, spark plugs, wires, fuel filter, air filter) and i clean the motor with that foamy stuff. could the spark gap cause this problem? i'm using bosch spark plugs instead of ngk. when the car is cold and i start it up, it might die sometimes. then i have to start it back up and rev a few times. i got spark in every cyl..... any ideas? thanks in advance http://forums.freshalloy.com/ubbthreads/images/icons/confused.gif

catalytic convertors never just "go bad"...there is a reason. Therefore just changing it out won't help any, without fixing the problem that caused the first one to go bad.
