Warm Engine Missing, Intermittent
Okay, I need some suggestions before I go into the shop again (that is if it doesn't heal itself on it's own). I have a 94 YJ w/2.5L 4 banger. 131K miles. I just had a new head installed. New Plugs, Cap, Rotor, Coil, Fuel Filter, oxygen sensor. TPS Adjusted, throttle Body Cleaned. Cool Air Intake kit installed. The jeep runs fine until it gets warmed up. Then it "misses" (Shudders)at acceleration and cruzing speed. (It does not stall, idle is smooth and only backfired once) Mostly but not always this happens at around 2500 to 3000 rpms. It's acting as if the timing is off just a little so that it won't take the fule at those few occasions when this happens. Do any of you wise folks have an idea what to check next? PS: The head, plugs and TPS was done first by a shop then I did the rest over about a month with no effect as each was done. I probably should start over and check the plugs unless you have other suggestions.
