Hey Everyone, I went through some major issues with my truck awhile back that I wanted to share with you. It is an 89 4.9 L6. I thought I would do the thing a favor and purchased and Accel 300 and the 375+ controller for down the road mods. I installed the equipment and the truck seemed to be OK but was a little shaky. I ended up taking her out and almost lit the thing on fire. Glowing red cat and all. Luckily I was able to limp it to the side of the road and let it cool down. I eventually got the thing home. So, a nice new coil and a multi-strike ignition. How bad could it be right? Well, turns out that this thing was mis-firing all over the place once I got it on the road. Accel says that the incoming and outgoing leads on the "Vehicle Specific Fit Harness" run alongside each other and should be separated. I was so disappointed with the system at this point I removed the system and kept the coil. The truck ran and still runs like a dream.

I am curious to know what is so affected by the RFI. Is it the TFI or the EEC? The module wasn't terribly close to either one but the wiring was in the general area. One other thing which was just silly was I tried some "Snake-Oil" pulse plugs to see if they actually did anything. The truck did the same thing that the Accel Ignition did. Everyone says it is RFI which I agree. I am just trying to figure out what I need to stay away from. I can't really stay away from the coil since the wiring goes right on it. I may just go to an MSD ignition and be done with it.

Any comments or info are appreciated.

Thanks,

Frank
