What codes are coming up? Is there a simple key off/on check engine light
blinking code procedure for you 4.7L guys? Just knowing the code isn't always
the answer as some of us have seen. Too bad you don't have a scan tool - if
you did, you could read all the sensor readings at the time of the check engine
light as the PCM stores them. A big help.
Keep the info coming and I'm sure you'll get some more responses.
Anybody know if the later models are still using the JTEC PCM design? If so -
unless they changed the code alot - I very seriously doubt that "Engine too
cold for too long" was the cause of the CE light.
