What about PIP(profile ignition pickup)? I think it's otherwise known as the pickup coil by most people. When I get issues like this I do diagnostics the hard way because I do not have a scan tool.
#1- I check for proper charging system voltage at the battery
#2- I check the engine vacuum, compression, and general engine condition.
#3- I check the power and ground supplies to the ECM
#4- I check EVERY SINGLE ECM input at the ECM AND at the sensor(tps, iac, egr, o2, map, ect, etc.). This method also checks the wiring between the sensors and ecm if you compare the readings at the ecm to the readings at the sensors. I also determine whether the sensors are bad OR reporting incorrectly because the mechanical element they are measuring is messed up.
The ECM is considered faulty after all of the above has been tested and found to be good.
Aww shoot, I'm getting back in the game again...
