I've got a 1990 Dodge Dakota with the 3.9 V6 in and have a real weird miss at high rpm. I checked and replaced the plugs,wires and coil and distributor but still it keeps showing up. I don't see it during normal driving but only if I put it in park and rev the engine up. I was trying to trace it to a cylinder by putting sparkplug test lights on three cylinders at a time but all I saw was a dimming of all three of the lights when the engine starts to miss almost like the entire ignition system is dampening. Does anyone know if there is some kind of rmp limiting programing in these engines?
