I purchased this car 3 months ago and have been driving it as a daily car since. One day I was running errands, after leaving a store I got in the car and it would not start. I sat there looking over the engine and could not find anything obvious. After a few cranks I got it started by pumping the gas, even though the car is a EFI. The car got me home but didn't have power above 3000 RPM's as a matter of fact it was like the engine hit a rev limiter. I replaced plugs, wires, cap, and rotor that day. I also since replace the mass air meter, MAP sensor and the computer. I'm getting spark to the plugs. It takes a while to start but after 3 minutes of warm up it will idle without and help from the gas pedal. After 5 minutes it will rev all the way to 6000 without hesitation, but as soon as I go for a drive it acts like its misfiring, and has a hard time to go above 3000 RPMs. The car is completely stock and is an automatic. Do you have any ideas?
