First, I have zero history on this car as I just bought it. It was running a little rough, missing.
I installed new AC Delco plugs and wire set. Cleared all codes. After starting it up and letting it come to temp, I got check engine light. Pulled codes: p0300, p0141, p0603.
I tested the ignition coils and got the following results:
Primary - Secondary Resistance
.2ohm - 5k ohm
.2ohm - 5k ohm
.3ohm - 5k ohm
.4ohm - 5k ohm
From the reading I've done, I'm getting that it should be .5 to .6ohms and 8k ohms on the secondary. Is that correct? If so, then is it a valid deduction that all of my coils are going out on me?
Lastly, is it a fair to say that it is possible that the random misfire could be causing the O2 code p0141 because fuel is not being burned correctly?
Thanks in advance for your input/help! cal
