Engine Power Loss After Car Is Warmed Up
Major loss of power after car has been good and warmed up. While car is at idle or revved the Tach is showing wide swings in RPM even with no motion of the pedal.
When vehicle is cold runs ok, sometimes a little rough but not bad. Full power.
Allowed vehicle to run for over 45 minutes last night at idle, died on its own, car sat approximately 20-30 minutes. Started wth no issue, ran rough at idle, lots of motion on tach. Took it for short drive approximately 2 miles total. During the last mile I had no power and was lucky to be headed downhill and then on a flat street. Vehicle died as I was pulling into garage.
Replaced:
1. Plugs
2. Wires
3. Cap
4. Rotor
5. Fuel filter
6. Fuel pump
This problem has been getting progressively worse with the problem starting sooner and the power being less and less. However it seems the power loss is ONLY when the car is warmed up.
Any ideas?
