1. Unequal compression. Valve clearances might need adjustment. Get a compression done if all others checks out ok.
I agree this would be a last resort since I parked one day and a few days later the problem occured.
2. Faulty Throttle Position Sensor.
That could be the problem. I got 5V for the baseline but I could not get a reading with my Voltmeter with the engine running so will try that again.
3. Low fuel pressure.
Possible but when I took the cap off and turned the key on. Fuel spurted out 6" in the air so there is some pressure.
4. Bad spark plugs, wires, distributor cap, rotor, ignition coil.
I did recently replace the coil when it died on me while driving, but cap, rotor, plugs and wires does not seem to fit the profile.
5. Valve timing out of sync. Was timing belt replaced?
Don't know the history of the belt but again seems unlikely given the suddeness of the issue, which would indicte more of an electrical/electronic issue.
Is the Check engine light showing? Check engine light goes out as it should. No codes when jumpered.
Was anything done prior to this happening? - Just the coil.
You are leaning to the throttle position sensor as opposed to any other fi sensor? Like O2 sensor or MAP? Thanks for your help.
