Galant Cat. Converter?

First question- do you ever smell rotten eggs when the engine is warm? If so you definately have a bad cat, and yes the whole thing just needs to be replaced. They are expensive, but they beat blowing the muffler up every thousand miles with unburned gasoline that pools in the exhaust. If there is no sulphur smell, there may be a problem with the cat, but there may also be a problem with the fuel injectors that are causing the O2 and cat codes to show while not setting an EFI code.

Well it might rely at the code you've got for the determine engine mild...however that vehicle must have two converters on it and $350.00 would now not be a nasty fee...the $50.00 Internet cat I'm definite isn't correct...I'm definite it is not OBD II and relying on how clogged up it's would motive large issues if you happen to force it's going to be pleased to reply any further questions, simply ask

put a vacume gauge on it open the throttle and then close it if the gauge hangs up slow to return to normal could be a pluged cat
