"... this is a gas engine and it only has the pump in the fuel tank. You're right about diesel's thou, they have 2. "
 
In addition to a diesel Rabbit with a pump for its injectors, I also had two BMW 2002s, and remember that the 2002tii had a separate mechanical fuel injection pump (Kugelfischer), and I thought perhaps the old Rochester fuel injection system for Corvettes had its own pump.
I did not realize that modern fuel injection systems only needed one pump in the tank.

I put the car in a heated garage today to work on it. Didn't get to do anything on it, but when I drove it to the (30 deg) garage, it was running so bad, I took side streets incase it stopped. When I left the garage and the vechile was warm (60 deg). It ran rather normal ( although when I blocked the wheels and put it in gear before I left the garage, the car would bog down and I actually had it floored and it wouldn't build power) - I did notice that if I sprayed starting fluid across the intake, the car would surge forward. Definately a gas problem. I took all the injectors out and inspected the screens at their inlet and they all looked v-clean
 
I'm thinking it's a vaccum leak, MAF/MAP, or Coolant Temp Sensor issue. I would lean toward the first 2 before the coolant temp sensor.

I will check the vaccum again while i'm having the problem. I did install a new combonation intake manufold pressure/temp sensor into the intake a few weeks back, but saw no difference

unplugged the trans computer, put the car in gear and with light/medium acceleration, still had the problem. - RPM rose smoothly to 2000rpm and then fell back to 500rpm kicking and sputtering as I continued to accelerate.
I pulled the timing belt cover and everything looked good, (installed 40,000 highway miles ago). good belt, tight, timing marks aligned, no loose, bent or chipped pulleys. cam sensor (which was replaced) looked tight and positioned correctly.

Same problem with the trans in neut or park. A little harder to notice without the load on it, but I can make it happen
