camaro 22

My car don't really have power in OD unless I floor it. Same thing in D while cruising around 2K unless I hit my brake and give it gas again. The exhaust even sounds funny, kinda like hesitant. What do you guys think this could be?

Fuel filter and pcv may need changing. Since you got a K&N "oil" air filter. It could possably be that you got "oil" on the mass air flow sensor by way of the oil air filter. I read where people get a stumble on acceleration, similar to what you're describing, and they clean the mass air flow sensor with "QD" and it then runs as it's supposed to.

You may also want to check you spark plugs and the spark plug wires.
