did you do a computer code check?

 

[viper94bite]

original code was p0303 after coil pack and ignition control replaced it says p0302. compression checks at 150ish for all cylinders.

 

[melsg5]

code P0302 may mean that one or more of the following has happened:

Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer
