ok, I thought I’d post this here instead of the engine forum. So last week my 81 d150 with the slant six and lean burn started to chug, well the truck was parked from Thursday till this Monday so I took it out and noticed that it was chugging along I took it on the hwy and it wouldn’t go over 70km/hr. I changed the plugs,cap,rotor,fuel pump and filter check the timing and it still won’t go over 50 now, when I floor it it spits and sputters and backfired and even seems like it dies but as I lift my foot off the pedal it sounds fine, what is going on here? I’m pulling my hair out guessing. If anyone needs a video of it running to see what I mean text me at+18078614536 and I’ll send you a video
