At this point the car revs up and down when starting. Going into reverse it will accelerate on its own, hitting the brake usually makes it run rough then die with the esc off light coming on. CEL is always on. Going forward the car will run for a few seconds then the esc off comes on with limited power. Have replaced: accelerator pedal, map and maf sensor, tps, pcv valve, input and output speed sensors. Trouble codes: p2173, p2106, p1295, p0300, p161b, p0507. The codes make me think its an intake or vacuum leak but I have sprayed and sprayed and cannot find a leak and help would be appreciated.
