First Of All....

Well I must say, you have both been helpful...
It is nice to get fedback from people with intelligence!
<<<<I understand that you can rev the motor to 5000 rpm and it just stays there without going higher? Does this happen in neutral?>>>>
Perhaps you misunderstood the above statement. In nuetral and/or park .... I can bring the RPM's clear in the red. While freeway driving, however, this is where I notice the most power loss. Like I said, sometimes she'll drive like new (Hit the gas she goes smoothly and fluidly without a hint of lag). Most of the time, however, it is difficult to accelerate above 60/65 without literally flooring it. And when the RPM's do finally rise (enough to enable the tranny to downshift ... hence RPM's rise) it will shift quite hard and then immediately up-shift. It's as if it doesn't have enough fuel delivery to compensate for the load. I have checked for any air flow restrictions... NONE!
Compression is 185 +/- 3 PSI on all cylinders..
I agree>>> Torque convertor problems are generally not intermittent. If it's bad.... it's always bad!
It's almost as if one of my sensors has a short / maybe one of the wires. But visually inspecting everything that I can / I see nothing out of the norm. Wires are not kinked, burnt, frayed (Nothing Obvious).
I wonder if perhaps my computer is bad, however, Ford says it is good. What R your thoughts on this?
Also / I've never bothered replacing my ECC Relay or Fuel Pump Relay. Can these be bad or intermitently bad? Perhaps they aren't supplying full voltage 100% of the time?
I appreciate your input and any further ideas you may have!
One last thought.... my transmission has an aftermarket modulator. Not sure who makes it, but it is one that appears to be adjustable. I have checked with Ford. They apparently make two modulators for this tranny. Neither of which are adjustable (Obviously the one i have is after-market). Ford manufactures two... High Altitude and Non-Altitude. Non altitude is about $40 and High Altitude is around $170 I am told, however, that without the original modulator/ they have no way of knowing what modulator I had. Is this bullshit or what. Surely there has to be a way of finding out.
Anyway, my question is would the modulator affect the way the truck drives. On again off again power. RPM's not rising etc?
Thanks again!!!
