I've searched under "hesitation" and got too many different scenarios. Here's my problem: I just bought this '96 (4.0, AW4) well, after it warms up to operating temperature, when stabbing the throttle I'm rewarded with a momentary bog or flat spot, it'll do it idling or moving in gear. It similar to the way a caburetor (remember those things?) with a bad accelerator pump responds. However when it's still fairly cold it's crisp, 02 sensor? (these things stay in open loop until they warm up, right so, the 02 sensor wouldn't come into play until then?) I don't know how long or how often it's been doing it as the Mrs usually drives it. I haven't picked up a repair manual for it yet........Hans
