Just finished my 318 rebuild on my 87 D150. Comp XE268 cam, Eddy 1406 carb, long tube headers, factory ignition, torqueflite 904 automatic.
Have driven the truck over the last few days and it runs great. Pulls hard through each gear. Was driving it around last night, putting it through its paces. Everything working as it should. I'm finally heading home and slowing down to turn on my street and it stumbles a little. Like a slight lurch. Was probably doing 15-20 mph. No backfire, no odd noises. It was just the engine skipped a couple beats and then kept going. Chalked it up to a fluke and parked it for the night.
Yesterday I leave for work, truck starts perfect. Warm it up and leave. The skip is back and it happens all the way to work. It would usually happen at lower RPMs in each gear. A couple of skips and then everything back to normal. I get into the throttle more after it would happen and it would pull good and hard, never do the skip again until I was under light acceleration and load.
Does it sound like an ignition miss? Its so isolated to a certain point of driving that I find it hard to believe its that. But I could be wrong. Maybe a transmission slip? Fluid and filter were replaced during rebuild as well. I'm lost on this. It was running so good and now this problem has showed its ugly face out of nowhere. Not sure where to start
