Intimidatorz34 Posted July 13, 2004 Report Share Posted July 13, 2004 Just wondering if anyone had a clogged cat and could describe how your car (3.4 preferably ran) I am thinking this is my problem because there is a lack of power and some lag when laying on it, and during idle and when backing off the accelerator while braking the engine shakes. Because there isnt a misfire or anything of the sorts. Quote Link to comment Share on other sites More sharing options...

Tru2Chevy Posted July 14, 2004 Report Share Posted July 14, 2004 Punch the cat with a screwdriver and see if it helps..... - Justin Quote Link to comment Share on other sites More sharing options...

mfewtrail Posted July 14, 2004 Report Share Posted July 14, 2004 Tap on the catalytic converter w/ a rubber mallet or something that won't dent it, if it rattles, the catlalyst material inside has broken up and the cat needs to be replaced.
