Lumpy six
I tried posting in the 80-86 forum but thought I’d try here.
1982 F150 I6. runs uneven with light throttle. Has had a new carb, EGR valve, intake manifold gasket, PCV valve, plugs, leads, rotor and cap. Took it out today on the highway and it felt a bit lumpy. After 15 mins, switched off and it dieseled a bit, first time it's done that. Got home and checked the timing, 6* BTDC as it say's on the under-hood sticker. I moved it to 10* BTDC and it ran awful, tried it at 8*, no better, so I moved back to 6*. Didn't go lower as it didn't idle too good. Any suggestions would be greatly appreciated.
