I have a 2003 Pontiac grand prix...I've lost power, it won't go over 30mph, it doesn't shift thru the gears smoothly. The service engine soon light goes off and on, more so when I'm trying to gas it. Its seems as tho it's 'being choked'...like not getting gas or air. So far, I've flushed the ******, changed the plugs, wires, air filter, fuel filter. I suspect the problem is a clogged cat convertor. I've been told that the exhaust can be opened a little near the cat to allow air to flow in....that should confirm if the problem is the Cat or not. I'm testing that theory today.

I had a similar prob where I needed to hit the gas to start my car, turned out the throttle body was all gummed up, after fishing it out, problem went away..
