When I stab or roll into the throttle I have roughly a 2 second delay before the car will really accelerate and build boost at that time the millivolts drop to <100 like 050 or 060. After the delay is goes right to 22# and mv is 700-800. I have replaced the TPS,IAC, and o2 sensor all with Delco parts. any ideas? It seems to act like no fuel, also have just replaced in tank fuel pump fuel filter and pressure is set at 42.5.
