I am still trying to solve this misfire on #1 issue and would greatly appreciate any advice or information. Thanks in advance!
I have run the engine with the 'plug in' for the coil unplugged but leaving the #1 coil and spark plug in place though unplugged from the car's power. This should protect the coil from being damaged. There are three wires going into that 'plug in'. The black ground wire is grounding properly, the red wire is under power without interruption, but the smaller yellow and black wire is dead. Should this wire be under intermittent power to determine the firing of the spark plug? If so, then I've likely got a break somewhere?? Also does anyone know the ohm (?) level of this wire and whether it would be sufficient to light up a regular circuit tester? Maybe there is power there, but insufficient for a circuit tester to read??
Thanks alot
