03 eclipse, 4 cylinder, everything stock. The problem I am having is loss of power in all gears when gas pedal is pressed hard and medium. When gas pedal is pressed lightly, acceleration and power is good
somehow I was able to fix the problem. I put the car into Park and then rev'ed the engine several times. I saw the RPM's stall and drop a few times and then kick back up. To verify everything was normal, I drove around the block and everything was fine.
the stalling also happened when I was driving. I could be at 20, 30, 50, or 65 mph and soon as I hit the gas pedal medium or hard, it was like the engine didn't recognize I was hitting the gas. There was no jerking or weird noises.
