'01 Tracker cylinder misfire

[sprintwrench5556]

'01 Tracker 2.0 check engine light is on. Code reader was #3 cylinder misfire. I replaced the coil pack on #3 cylinder and all plugs, cleared the code. The engine still runs like is has a misfire. Check engine light came back on reader now reads multiple cylinder misfire detected but. Any ideas? I also done a compression check all cylinders are as follows #1 185 #2 195 #3 195 #4 195. Changed the fuel filter and removed the fuel injectors cleaned them w/ aerosol spray cleaner. Still no change. I adjusted the cam-shaft position sensor, the engine misfire has let up some but not completely. I've cleared the code but don't know if it will come back. HELP!

have you changed the plugs and made shure they are gapped correctly?

Use a noid light and make sure you have power to this injector. Use a stethoscope and listen to the injector make sure its working properly.
Ohm the injector and compare to the other injectors.
Pull the plug wire put in a spark plug ground the plug have someone else crank the motor. Make sure its sparking maybe a bad wire between the coil pack and spark plug.

If the misfire is still on cylinder 3, roll the injector to another pos.

Misfire is now a rolling misfire between all the cylinders it is no longer just #3. The code reader now reads cylinder misfire detected it is no longer cylinder specific. I have now retarded the cam position sensor all the way the misfire is no longer read by the computer but the engine is down on power.
