Question about 1999 Ford F150 Regular Cab
Difference. if the weather warms up, truck runs fine. same problem for the last 3 years
SOunds like you are not getting dle enrichment during cold engine operation. Go to AUtozone or other parts store and they can run free diagnostci test for you to see if you hvae a fault code sotred telling you what is the problem.
Possibly injectors need cleaning. Buy a bottle of Techron Injector cleaner & add to fuel tank.
ALso, you MAF mass air flow sensor could be coated. Clean gently with carb cleaner. It is in air cleaner system or tube and has a small wire harness going to it. Good luck.
