misses at idle, no driveability problems
89 F250 4x4 5spd runs and drives great. New plugs/cap/rotor about 2 months ago, wires looked good so I left them.
In the mornings I get in, start the truck, let it warm up a bit then drive 25 miles to work. When I get there it will idle but theres deffinitely a miss, a stumble at idle. If I give it just a tiny little gas the stumble gets more pronounced until the rpm get high enough to hide it.
Never stalls or fails to idle, on the road it feels normal at all rpm ranges and loads, no bogging off the line.
Can try the plug wires, won't hurt but I doubt thats it.
I've read here that the coils on these were a little weak, any way to check?
Other thoughts/ideas, thanks, Matt.
