looking at your spread sheet on knock counts v. map v. rpm, I don't have knock counts in every cell but the very few cells that do, I am seeing upwards to 40 knock counts sometimes. This may be a dumb question but, the way I see it, I have something knocking internally, would you say I should take those readings into consideration that my engine is finally going out or that I'm overlooking it?
I mean it does have 319,000 miles on it now and I have never dropped the pan , change head gaskets nor pulled the motor. It just blows my mind that the truck starts up and runs fine up until it warms up, then it develops the distinct-able miss while I am at a stop light idling.
