91 C1500 5.7 idle miss
Truck does not sound the same and miss began yesterday. Plugs 2 yr old. New coil (Accel) tps, ignition control module, idle air control in the last couple months as preventative maintenance. Replaced o2 today. Truck idles bad. Egr 5 years old. When I disconnected the timing wire to check timing, truck almost died so I could not complete. Any suspects?
