Ok, here's the update. 1993 xcab xlt 2wd auto
Bought with dead cylinder. Fixed, had a hole in exhaust valve.
Runs rough, change plugs-motorcraft-, rotor, wires, cleaned the oilpump.
This has been going on since I purchased the truck.

OK it has never run correct since I have owned it. Checked fuel pressure 34 KOEO, 40 KOERunning Checked the regulator attached vaccum pump and held 15psi for 1 hour.

Truck runs , and will get upto speed, but it surges and has NO power. A small uphill climb will make the truck loose 15mph.

Anyone got any ideas?
I am really ready to sell it and cut my looses.

..scrathing my head.
