The previous owner put the GT40 heads on the car when changing the head gaskets from when i believe the owner before him blew one using nitrous(the line is still in the car). That is what I'm betting on anyways
So ever since i bought the car it hasn't ran great. It runs rich all of the time, I'm getting about 10 mpg with the factory 3.06 gears. The real problem tho is that until it gets some heat in it if i try to pull off nice and easy the engine cuts out and bucks several times. it sounds like i get backfires out of the axle dumps when this happens as well as the smell of fuel which leads me to believe i am intermittently losing ignition at low rpm with load until the car is warmed up. To avoid this i must pull off at a decent rpm(2.5-3k) and let the clutch slip until it really gets rolling(I heard "Bad driver" jokes for days the first time my buddy witnessed me slipping it while cold) once it warms up it runs substantially better. The bucking problem no longer exists and it pulls decent aside from the fact it is pretty fat. Backfires(made you jump kinda backfires) through the exhaust are common on power shifts even when warmed up. I'm throwing all the EGR codes but the only performance code I'm throwing is Cyl 8 failed balance test. I hope to investigate cylinder 8 this weekend.
I don't know a lot about Ford's EEC so i am hoping someone here may be able to help me connect my dots. What sensor feedback or ignition component could cause ignition to cut out when cold? I haven't dug into it yet but i am hoping cyl 8 has a stuck injector which may explain my fuel consumption but wouldn't explain what i believe to be a loss of ignition when cold.
Any ideas? The engine has been abused and has had many hands on it before myself, I have a 5.8 in the works but until it is finished i was hoping to dip my feet into autox with this 5.0. but right now aside from some exhaust fire on power shifts the car is not very respectable lol
