Just went through this last week end. Had to get the book out and follow directions. Did not help much, I think the head gasket let go between 4 and 5. Pulled the compression tester out, 140 at 1. 138 at 2. 140 at 3. 30 at 4. 30 at 5. and 140 at 6. Truck has been a daily driver for the last 2 to 3 years. All at once this started running rough and now waiting for time to pull it down. But yeah, we put the wires on wrong a couple of times.
