Here is what I did at lunch time,
I run a KOEO test and got two codes:
#222 Distributorless Ignition System Loss of Right Ignition Monitor(IDM Signal)
#327 EGR Valve Position Circuit Below Minimum
#327 also means EVP/EPT Circuit Below Minimum Voltage
Is #222 Pointing at a bad ignition coil?
Is #327 Pointing at a bad DPFE Sensor? From what I learn so far this is the only place that the PCM gets feedback to check the pressure differential which is reflected as a voltage change.
I was told that the ICM Ignition Control Module "must" have the four screws for good ground. The one on my truck only has three. Could this be also shown as #222?
Thank you again,
