Dtc P0355

[roy]

Causing back firing and and a engine miss.

Did continuity checks from Pin 60(PCM) to Pin B (ign coil #5) = continuity
Did continuity Checks from Pin 56(PCM) to Pin C (ign coil #5) = continuity
Checked for shorts to ground for both Pins = No shorts.

I put everything back on the car, ran great till the third shift at redline . It started to misfire and back fire out the exhaust. Throws code P0355.

I double checked everything again I then even switched a coil , plug and plug wire just for giggles. Didn't change a thing it still gets P0355 ign control circuit.

I am guessing the PCM is the culprit since the ign control circuit is in the PCM (right or wrong). But before I purchase a new PCM anything else I should check?
The car is a 98 camaro with the 98 operating system still.

Sounds like you did the stuff to trouble shoot it. Peek at this link and see if there is anything else to check on that trouble code.

I'll rerun the the tests again tomorrow, but I think I will have the same conclusion.

Nice link, looks like a lot of dedicated work you put to it.

Thanks, most of the Helms manual is in there somewhere. Someone asks a question, we try and give them the info.
