Start truck rough idle very low, eventually shuts off. Checked plugs were covered in black soot. Rebuilt engine five months ago, rebuilt transmission in December. New plugs, cap, rotor, wires, rebuild TBI kit, TPS, IAC, fuel filter, fuel pump, ect sensor, fuel pressure regulator, timed correctly at 0, get codes 15, but that is heating issue, gets fuel no problem, spray pattern seems good and wide. Just wont idle. Checked for leaks over and over, none. Checked wires all good, I know it is something minor but seems major. As soon as it starts less than 30 seconds it is dead. New distributor and module. I am really lost here, but wont quit I have invested too much money and time. It ran perfect two weeks ago then some bone head idea I got was to install a adjustable fuel pressure regulator but it wouldn't hold pressure. The gauge was leaking so I went back to stock but now it wont stay idle. Just before it just shuts off now. I did get to drive it and it had no power what so ever. Now it just starts and runs really rough or shuts off in 10 seconds.
have the same problem?
