Question about Oldsmobile Bravada
I read your problem.
I have some ideas about that.
You are right, The pressure should stay olmost the same.
But, I'm , involved in problem with aftermarket fuel pump.
I recomend A/C delco or Carter. fuel pump.
Check the Pressure regulator, that goes in the rail of the injectors. Inside of the intake, Some times is leaking.
Check the EGR valve, The carbon make the valve no close correctly, Take it out and check the pivot, they have to stay close.
Check the ground in all around of the car, speciallity the one on the frame rear , for the fuel pump.
If after all you still have the problem, Disconect the transmission seleniod connector, and put in drive, if the problem go out.
check for short cicuit in the wires and connector a transmission..
Is there more thing, but I hope this help on someting.

If wiggling the wires cured the code, then one of the wires is broken inside the insulation. Pull on each wire one at a time. look for the colored insulation to stretch, this will be the broken wire. For the other car that wont rev up, this is a common when the catalytic concverter is plugged up. This will also cause MAF codes, and in turn, TRAC OFF light.
