if the cat rattles it is broke up inside. you are describing a dead cat converter. jimt > Hi guys, > driving from Pittsburgh to New Jersey, I ran into the following: first, sudden loss of power, especially up hills, etc---pretty independent of which gear your in. Later, power returns, but engine is very noisy---like a car without a muffler (although perhaps not quite that noisy). Other than that, the engine seems to run fine now, and the noise, it seems, can only be heard from the outside---that is, with the windows rolled up, driving on the highway, you don't notice it. Roll down the windows, or get out the car, and its VERY loud. > > My thought was: some ceramic in my catalytic converter broke up, at first clogging the exhaust, but then breaking free and letting more exaust through---thus returning the loss of power, but muffling the engine noise less. Does this sound right to people? If not, what should I be looking for? And if so, I can just drive it like this until I have to pass an emmissions test, right? And how can I try to find a cheap cat? > > Thanks very much for any help. Oh---and the van's an '84 manual. > > Another thing I noticed---there is still "exhaust" coming out of the tailpipe, but you wouldn't know it if you didn't stick your hand right behind the tailpipe---it's not black at all. > > Thanks again, > Wes > |
