Low speed hesitancy...

[pwrplay]

Yes, I know this subject is not new and I have seen many posting around this subject. But every one is different and doesn't quite fit my truck's behavior. As many of you know, I have one of the highest mileage 5G here (90K) and she's been just about perfect in every aspect. Lately, I've noticed a peculiar behavior after starting my truck (cold or hot). When I put her in gear and creep off standstill (1-2mph) to maneuver around parking lot or my driveway, the throttle hesitates as if like a switch turning on and off. This makes it very difficult to drive slowly. If I put more gas in, everything is ok but I'm going faster than desired. After driving for a few minutes, starting off a stop will be normal again. If I shut it off and immediately drive off slowly, same hesitation occurs. According to all the other posting about hesitancy, is this pointing out to a failing injector(s)? Confused...

I just came across this thread whilst searching for info on a similar issue I am noticing with my Ranger. Did you happen to figure out what the issue is/was?

Thanks, I'll keep that in mind if it gets worse. It doesn't seem to happen all the time right now.
