Im experiencing a problem with my engine. this happens constantly. It feels like the engine is loosing or chooking on fuel. If i keep it at a steady rpm while in neutral u see the rpm fluctuating. I have changed the fuel filter, fuel pump, plugs and wires rotor and cap! I donno what else to do! Can anyone guide me to a solution! Or have an idea what im talking about? Thanks!

is the ecu throwing any codes?
vacuum leaks?
o2 sensor?
check on those, hope that helps

What year is the motor?

What was done to it?

Just swpped it recently?

All vacuum hoses checked....all electrical components changed and double-checked....tightened, torqued...no breaks in the wires? Or ceramic houseing of the plugs?

All sensors checked? properli installed?

Ignitor, distributor components checked? In working specs?

I just have bolt ons on it you know ur usal i/h/e. Everything is pretty much stock, except the new fuel pump! The engine light is turning on, i think it might be the o2 sensor, but then again i have to take it to the shop to get it downloaded.

you can check the code yourself...o2 sensor is dtc 41....there is a blue plug under the dash by your ecu....put a paper clip in it so that you connect the wires (complete the circuit) and then turn car on for a second, the check engine light will flash your code. Long blinks are the first number short blinks the second so 41 would be four long blinks followed by one short.
