I was scanning my car last night trying to find a problem,then noticed my ltft's were spiking at +36.
Showing no misfiring cylinders,scrolled down,primary misfiring cylinder-15,secondary misfiring cyl,-15.
I thought that the highest ltft you could get was 16,and a big? for the number 15 cylinder misfire.
This pcm seems to be fried because the snap-on scanner has worked fine with the last 8 vehicles.
Also have extra pcm from a regal with same service number,but security is enabled and it would not
accept the security relearn.Thinking about running a ground to the anti theft pin and see if it enables fuel.
