I just bought an 88 f250 and the guy I bought it from said the ip was turned up and this thing is loving the fuel is it as simple as just turning it back down or is there more to it

yeah you can just turn it down, turn it down a wrench flat at a time and then drive it again. but since fuel delivery is entirely based on the metering device in between idle and WOT, you can get the same effect by sticking your foot in it less. drive it like one more RPM will make you asplode and ignore the people behind you for the best mileage.

Alright man thanks I will take the lead out my boot

If you arn't getting black smoke when you floor it, then the IP is fine turned up. A little black smoke for a couple of seconds is OK also.

 

[Fs2m5a0rt]

This dude rolls the black smoke and I mean roll

 

[drinkypoo]

If you're making black smoke any time other than a little at start or a little when under heavy load (e.g. uphill with a load) then something is wrong, either timing excessively advanced, fuel turned up too far, air filter clogged, or some combination thereof

Yea I'm going to try backing down the fuel abit I think the guy might have went a little happy with it
