WILL NOT OPERATE WHEN PUT IN DRIVE OR REVERSE, CRANKS IN PARK

2002 Ford F-150 • 157,000 miles

Truck has had two ignition coils replace in past 3 years. Has been running rough when going from low speed to higher speed the levels off. Now cranks easy and sounds fine with 2500 rpms but when shifted from Park to drive or reverse, idles down to less than 1000 rpms and dies.

Try cleaning your throttle plate on both sides and iac hole with choke cleaner, the plates get gummy and sticky and will do that.
