 89 f150 hesitation and stalling
I have an 89 f150 w/5.0 eng. It starts and runs fine for about the first 15 minutes and then will start to hesitate and then stall. It will start back up, sometimes taking a little longer than others. It will idle fine with no problems. Fuel pressure is solid at 35 psi. The coil and fuel filter just were replaced along with rotor on distributor, cap looked fine. Switching between fwd and aft tanks makes no difference. It has these 3 error codes that im not sure are linked to my problem 25,33,44. I would appreciate any help that anyone could give me. Thanks |
