View Full Version : #2 Cylinder is not firing

10-08-2008, 10:29 AM
I ran a cylinder balance test, trying to identifya miss, and got a code 20 (cylinder #2 not firing properly) code.

I have installed new spark plugs, new wires and checked compression. Compression reads 180 on that cylinder (compression in other cylinders ranged from 165 to 180).

Any suggestions?

Coilpack, injector, or injector wiring.

You can check the coilpack by swapping the plug wires for cyl. #2, and cyl. #5. If you still get a misfire code on cyl. #2, then the coilpack is ok. If the
misfire code moves to cyl. #5, then the coilpack is the problem.

Compression between the highest and lowest cylinders should not range, Healthy engines give a difference of less then 15lbs
