Car is a 90 5spd sc
I got codes (Key On Engine Off)
22 - MAP sensor out of range
67 - Improper signals from clutch switch?
I got these codes from the (Key On Engine Running)
42 - 02 sensor "rich"
33 - EGR valve position
77 - operator error during dynamic response portion of engine run self test
74 - brake on/off switch action not detected during dynamic response portion of engine run self test
alright let me clear this up...
my map connector is broken so its not connected, the harness is just resting there. 02 sensor is getting some weird readings because i have an exhaust leak. the egr was removed by the last owner. the last two codes were because i didn't lower the e-brake when the scanner beeped... my fault so forget codes 77 and 74 there usually not there i messed up this time
also, the car will not go into boost, as soon as it goes into boost on the boost gauge the car starts bucking, fuel pressure is 42psi with the engine off, and 38psi with the engine idling. As soon as the gauge goes past 50psi the car bucks, I can get the car to make 12psi of boost and 60psi of fuel pressure if i floor it but the car bucks really nasty and i have to let off the throttle so it won't stall.
also, i just noticed that while the scanner does the egr test the exhaust leak seems to go away for a couple seconds, then once the test is done the exhaust leak comes back. anyone know where the egr valve is located?
