Default Re: Ruff Idle ,Huge Loss of Power

I had accidentally interrupted this thread in the middle with my hesitation issues and apologize, but have been following it and with some advice here and just some old school stuff finally got around to looking into my stumbling / hesitation issues. If felt like an old fashion mis and so I hooked up my timing light to each plug wire. Been awhile since I had t he timing light out. I went down the line up with cylinder 1 first then 2 etc. Sure enough once I got to plug 5 the light started shuddering, not the constant pulsed flash of the first two cylinders. I kept going and sure enough 8 was acting the same way. So upon some research the WSM etc. I saw that it is the same coil that sparks both cylinders, so pretty sure I found my issue. I haven't started to start the operation yet, but have all new coils and wires and also decided to splurge and get new FIC injectors. I had used them previously on a 91 ZR1 I had and was really happy with the response. I am looking forward to getting started, It has been too long.
