Periodic rough idle when warm
My 95 4.0 has had a periodic idle issue for quite a while. It seems it may be getting worse. Here is when it only may happen:
Vehicle is fully warm. I shut it off for about 1 hr or so and when I restart it, it shakes and misses in idle. It will idle fine after I drive it around or if I rev the engine for a while when still parked.
This never triggers the "check engine light".
New fuel filter, plugs and wires.
