Re: Won't go above 45 MPH

I had this happen on an '86 Trans Am - it was a blocked cat converter. It's easy to test, just drop the pipe - and go for a noisy test ride

BTW: eventually, it will get worse to the point that it won't run at all - especially after it gets hot. The cat will completely block off the exhaust until it cools down.
