just a check engine lightAny codes (CEL)? Loss of power can be alot of things, low fuel pressure,vacuum leak,etc
by doing this, what would it prove?Un bolt the cat from the manifold and go for a drive
your gonna wanna get the codes pulled . this could lead you right tojust a check engine light
Actually great advice. A lot of people want to throw parts at it first. Keep it simple and try the free stuff. I've seen this plenty of times as well. The newer expeditions are real bad about it.If your catalytic converter is stopped up, which it sounds like it is, um bolting the cat will allow the engine to breath. The only reason I say do this is because I seen this a thousand times where a customer would come in explain the same thing you said. Then tell me that they replaced all kinds of s**t and you tell then it is the cat they are like that is not possible. So just undo the two bolts at where the header meets the cat and go around the block.

first off, im i-car, and ase certified, and worked in a honda dealership for over 4 years, then on to a cadi dealershipOk first of all you just don't go to the damn auto parts store and pull the codes on the 88-91 civic. Second of all yes there are alot of kids on here but you should think before you speak. Some of us are ase master techs who have got more time on a ratchet then you do siting in the seat of a car. You sure as hell did not give this person very good advise so the best thing to do is keep out of something until you can give positive advise.
