I finally figured out what was causing the problem and what code 28 stands for.
The problem was with one of the coil packs on the electronic ignition control moduel. After making several calls I found out how to test them.
- with both wires of one coil pack at a time. Start the engine and look for arcing across the two terminal posts. If it does not arc then the coil is bad. The Coil can still fire a plug, but not with enough juice to create a good spark.
The code 28 refers to the abs system onboard. On of the wheel sensor sences a wheel spinning at a different speed than the rest of the wheels.
