Sweet thanks. I got rid of the Cat. However that didn't solve my problem. If you Wide open Throttle it, it bogs and spits and sputters. If you baby it, it seems ok. I have replaced plugs,wires,cap and rotor, new fuel filter, fresh hi octane gas with Lucas fuel injector cleaner. Purge valve checks out ok. Its only got 39K miles on it. Is the accelerator pump adjustable? I took it apart and no tears. What else am i missing?
