1990 5.0 EFI, manual trans...all emission controls except PCV gone. Have tricked most so that engine warning light stays off. 70mm mass air flow sensor, 65mm throttle body, 24lb injectors, X3Z computer.

Receiving the following KOEO codes:

81: Air Diverter solenoid fault, intake air control circuit fault / air injection diverter

82: 1) Air diverter solenoid circuit fault or supercharger bypass circuit fault (no supercharger) 2) Integrated relay control module

85: Canister Purge Sole4noid circuit failure.

Any way to get rid of these codes? Could any have anything to do with bucking/jerking at low-speed, low enginge load conditions?


Continuos Memory Codes:

14: Ignition profile pickup (PIP) circuit failure

29: Insufficient input from Vehicle Speed Sensor (VSS)

33: EGR not opening properly (duh)

Cheers, Dale

With resistors as proscribed on forum. One was EGR Valve Positision Sensor and another was a resistor across a rectangular two-prong female connector. At one point the TAD/TAB were fixed, also. I'll have to check those.
