97 Lumina 3.1 POLICE PACKAGE misfire cyl 1. Here is what I have done so far.
1. New wires
2. New plugs (started getting the misfire after changing the plugs)
3. New coil pack
4. Checked compression 180PSI
5. All new injectors (should have tested electrical system first)
6. Checked cylinder 1 wire harness to injector, getting a steady light (not pulsing) Would that be a PCM issue? I'm assuming if the LED test light lights up on that circuit than I should not have an open in the wire right? Thanks in advance
