I have a 1989 Winnebago Chieftian with a 454. Had to remove the exhaust air pumps due to leaks at the manifolds. Now exahust has a heavy gas smell. What can I do to correct this problem?

Install a decent set of headers and re-jet the carburetor. Your billfold will thank you!!

Or replace the Quadrajunk with a Edlebrock. The headers would be a good Idea but really won't benefit from them without duel exhaust or if you have a few buck get a Banks system.

I'm lost. I've gone to look for me. If I should return before I get back, please ask me to wait.

I'm no sure, do you have a carb or have throttle body injection? If carbed start with a good tune-up first,then clean out/or rebuild the carb, and correct the leaks, If its injected, fix the ehaust leaks for they will cause the oxygen sensor to read lean and add fuel.
