Ive had the car stumble a couple times and actually shut down on the highway once. (it restarted itself) and the check engine light came on. When I checked for codes I got 1-4-4. I have cleaned up the connectors for the power stage and FI resistor pack and replaced the FI relay below the radio. I'm just wondering if anyone else has had this problem and what the fix was, I really dont want this to happen again while I'm fighting rush hour traffic.
Car is a 93 945t
