I have been having a problem with my Ranger since I got it two years ago that I haven't been able to pin down. The truck will sometimes lurch like it cuts out for a second when shifting gears, or letting off the throttle and accelerating again. It runs fine after warmup and on the highway, etc. But I can reliably make it do this by letting it idle for a while then driving it. Stop-and-go traffic will do it, too. This didn't occur really at all when it was cold during the winter.
I was thinking maybe while idling something gets heat soaked, maybe a temp switch related to the emissions control system that then makes an adjustment. I haven't seen any overheating or anything like that.
Could it be something with the catalytic converter? Or bad fuel pump/vapor locking? I have a fuel pump that I got on sale on my shelf, maybe I'll just put that in and see what happens.
The truck is a 1983 with feedback carb and 4 speed. Has anyone else experienced something similar? I haven't been able to find a diagram of how the emissions control components really work and what they do. I suppose nothing like that exists as it probably would have been a trade secret or something back in 1983.
