Question about 2003 Ford F150 Regular Cab
Engine pulsating whtle idiling in park no light or code need help
I had a similar problem for some time then finally had a code which was lean fuel from air being sucked in through the manafold leak beyond the injectors.
It turns out that there is a TSB for a manifold leak which requires a new intake manafild gasket and bolts.
Luckally I had an extended service agreement or it would have cost me hundreds...
