My '94 Kick has 87K miles. Starting last spring, it would mis-fire (stutter) for the first couple blocks, when starting off cold, at partial throttle. It doesn't seem to misfire at idle, low RPM or high RPM.
Then, a couple tanks of fuel ago, it would stall in 1st or 2nd gear. (Over half throttle, and when it's warm, it runs fine.) It stalls for 3 to 5 seconds, then takes off again.
The wires, cap, rotor, O2 sensor, sparkplugs, are all new. It only does it when cold.
The shop suggested I do a fuel filter change & "enginevac" (cleans out fuel injector, intake manifold and cylinder carbon). I also had them scope the engine with no results. I've run 4 or 5 cans of water-remover through the gas tank, so I don't think it's water in the fuel.
Now the shop is saying the new wires may be at fault. He's ordering wires and sparkplugs.
What do ya'll think?
