I picked up an 88 5.0 w/ aod recently. When the car is completely cold, it starts every time but will idle at like 400-550 rpm's it's amazing the car doesn't die, but it keeps going. No throttle response at this point. After about 3-5 minutes of letting it sit like that, then it immediately bounces up to about 750-800 which is where it should be. Then the idle just stays right there. I went out and watched the fuel pressure gauge yesterday during all of this. Fuel pressure sits right at about 40 while the idle is low. Then it drops to about 33 when the idle finally jumps to where it should be. What would cause this and how can I correct it?
Car has aeromotive adjustable fpr. Timing set to 10 degrees. Car was swapped to mass air by PO, but they screwed it up. First, they put in an A9L instead of an A9P. Still has an aod trans and matching O2 harness. they did run the 4 wires from the meter to the correct pin locations, but they did not move the wires from 51 to 38 or 11 to 32. Could the mass air have anything to do with this?
