ok here's the deal, 94 xlt 4wd pretty much all stock with 110k. it has run like new until about a month ago. I went up to chicago to pick up the 91 sport. It towed back just fine, however ever since then when I'm sitting at a redlight it feels like it's missing on a cylinder every couple of seconds. It's just fine when you're accelerating and driving normal. Sitting at a stop light though after about 10 seconds she'll start to give a little kick every now and then, never a steady pattern. She has been well maintained, the plugs and wires were just changed about this time last year. I checked the plugs, they look like they're at the halfway point. The only other thing I can think of is the EGR. Anyone else have any ideas???

One possibility is it could be the IAC on it's way out.
 






dang:( I've put over 60k on this truck without any problems. I'm gonna go ahead and change the plugs. Does anyone know how to check if the EGR is actually working. I know the IAC is easy to change, but I'm gonna try and make it the last thing on the list, just seems funny that it would go out after a towing episode, but could be pure coincidence.
