Fuel pressure regulator?
My problem is the idle runs extremely rich and it acts like its dumping WAAYY to much fuel into the engine. I mean this truck gets 10 miles to the gallon now.
It wasnt always that way.
My symptoms.... Lopes at idle, can't press gas pedal past 50% will die at idle under load. Will die on highway under 51%-100% load. Black smoke (fuel) Smokes really bad at idle.
It would do this in the past but it would only be episodes. Kind of like my truck having a period. Shes a fistey one.
Now shes completely biting my head off everytime I drive lol.
I took the vacuum line off the fuel pressure regulator but it did not change a thing.
Well now sense its been idiling rough the fuel pump doesnt shut off.
I can hear the intake sucking really loud at 50% and if I try to press anymore it runs rough and dies.
Weird eh?
So do you think its the fuel pressure regulator? The intank fuel pumps work.. The fuel pump works.....
I am going to pinch the fuel return line tommorow. And see if that does anything. I will update everyone. Untill then. all advice is sure welcome!
