I checked for arcing at night. No arcing. I rechecked and set gaps on the new plugs I put in.
The p2308 code is an error in the ignition coil #3. Coil #3 fires cylinders 2 and 5.
Erased the code. Then I flopped sprk plug wires from another cylinder for the number 2 wire.
I get the same p2308 code come. I did the same with the 5 cylinder wire with the same results.
So I am pretty sure its not the wires, plugs, and coil (which is new).
I checked with a TEST LIGHT the control wires for all three of the coils with the engine running.
Pin #1 (brown/orange wire) control wire for coil #3 LIGHT GLOWS CONSTANT. I think this is wrong.
Pin #4 (dark blue/tan wire) control wire for coil #2 LIGHT FLASHES - I think this is normal.
Pin #3 (dark blue/dark green wire) control wire for coil #1 LIGHT FLASHES - I think this is normal.
Since the control wire glows the wire must not be bad or grounded. I think the pcm must be bad.
Probably a good bet the computer is bad and should be replaced?
I don't know. Is there anything else I should check? The pcm is expensive. What do you think?
Any suggestions on replaing the computer if you think I should?
