5.0 Stalling Help
I have a 1986 f150 with a 5.0L fuel injection. It has a major stalling issue. Was wondering if any one had some ideas? When you accelerate, up to about 1/2 throttle, everything is fine. It will get up and go just fine. Floor it, it stalls like it is starving for fuel, let off the throttle, it recovers fine.
It will surge so bad it shakes the whole vehicle.
Went to the dealership,
they have no way to check that old of a system.
1: starts and idles fine, no roughness associated with clogged injectors.
2: idle control soleoid works normally, and resistance value normal.
3: new tank pump, high pressure pump and fuel pump relay installed. direct reading guage shows normal pressures and when flooring it, pressure recovers great.
4: throttle position sensor responds normally and resistance is correct.
5: truck starts and runs down the interstate normal, just don't floor it.
6: code reader says everything is bad basically, excypt the self check on the computer.
7: unhooked EGR valve, no difference. resistance value normal.
I am at my wits end.
Any ideas?
