Got a 93 300SE that I recently replaced plugs, wires, rotor, rotor cap, coil and fuel filter. All done in effort to hopefully eliminate an intermittent hesitation. Ran fuel injector cleaner through several tanks of gas. Bought and applied some CRC MAF cleaner. Helped some, but hesitation would every now and then reappear. Then the weather turned unusually cold and I haven't seen a hint of hesitation now for a couple of weeks. Had it continued, I was going to replace the MAF. Opinions? Thanks!
