Whenever I step on the gas the RPMs drops unless I ease into it, almost like it flooding. The RPMs will only go up to 2,500 RPMs if I try to go past that it plummets. Has new spark plugs and wires, a new distributor cap and router, new fuel filter.

Hi,

Have you checked the fuel pressure to make sure it isn't too high or low? Have you checked for engine vacuum leaks? Also, have you checked to see if there are diagnostic trouble codes stored?

Let me know. Also, if you haven't checked for codes, here is a link that explains how to do it. You don't need a scan tool on this vehicle. All that is needed is a short jumper wire or even a paper clip. Follow these directions and let me know the results:

What you described sounds like it is starved for fuel. That is why I'm suggesting checking for codes.

Let me know what you find.

Take care,

joe
