97XLT ohc v6 loping idle/no power

[WORKIN' FORD]

Hey guys. I'm in a jam. I use my truck for work, and one day, while at a job, my battery died in my X. I jumped it, and not even half a mile down the road, the motor started to run poorly. My first problem is that it lopes in idle between 700-1000 RPM. My bigger problem is that it has no power. Climbs hills doing 6-10 mph floored! Dealer had it for a couple days, and replaced the spark plugs and MAF sensor. After three hundred dollars or so, I felt they were wasting money, especially that i had replaced the plugs and wires not too long ago, and took the truck back. I had replaced the battery for a start. Things that I have checked are camshaft pos. sensor (no reference voltage with KOEO??/sensor reads approx 500 ohms), crankshaft pos sensor (voltage on both pins 1.5V??/sensor reads approx 450 ohms), spark plugs look good, pressure checked the exhaust (no blockage). I had also checked cyl 1 timing with a timing light just to watch the spark pulse. It does seem to miss every now and then. I've looked at fuel pressure only as far as the pump comes on and the valve in the fuel rail sprays ok. I'm pressure checking it this weekend. I'm thinking that a fpr may be faulty? I've swapped the computer and the new one does the same thing. No CEL. :frustrate

Any ideas? My head hurts and I could really use some help here. You guys seem to know quite a bit on these ford motors. I deeply appreciate any help you could give me. Thanks in advance.
