hi! I have a 1991 f350 7.5 Dually automatic and it’s running very rich and i’m not sure why
I’ve changed the spark plugs, spark plug wires, fuel pressure regulator and a few other things
a little back story: i got this truck with very low mileage 87,000 and one day the battery was dead so i jumped it it started but the rpms started to dance would stall from time to time. it hesitates really bad and if I hold the gas it’ll jump and go it won’t go over 30 mph please help in anyway you can!
thank you -Joah
So this started after the battery died? If yes, then it's probably the ECU re-learning parameters.
okay I was thinking something along those lines. I've just dumped so much money into trying to fix it myself that I'm just going to take it into a shop. thank you for the help I plan on asking how much itll be to replace that! again thank you!
