- Pretty deep subject.
- See if it shows any codes 1st, Turn key off and on 4 times
- without starting the engine. This will cause the power loss
- light to start flashing codes. Ezxample:
- Flash.....flash..........flash.....etc. The long pause is the
- separator for the tens digit. The one demoed is code 21. The
- sequence is over when it flashes 55.
- ..
- Now, the problem you describe could be several things, Throttle
- Position Sensor, MAP sensor(located ON computer behind passenger
- side kick panel), Air temp sensor(located on intake manifold in
- middle top). Those are most common, also possibility of carbon
- build-up on the valves although this usually causes cold
- drivability problems.
- Check the codes and let us know what they are.
