i lifted the car up and put it on stands and i took it up to 70MPH i kept it there 4 about 3-5 seconds and it suddenly shut-off some one had replaced the ignition control module and did not put any electrical grease i guess it burned out i installed the one of my other camaro and put grease on it and it started so im guessing the other one blew out do you think it was due to it not having any grease or could it be that my ecm is not functuning correctly.
