i have a 1992 9000 turbo 5spd w/tcs, and its been acting up,, alot recently

the physical symptoms are as follows, its run rough, can start hard, and it lags out under hard acceleration.

on further testing i found these codes in the computer
12224:Air/fuel mixture to rich
12111:incorrect air/fuel mixture while driving
12251:????
12112:Incorrect air fuel mixture at idol
12223:Air fuel mixture to lean

it seams pretty clear that something is wrong with my mixture, i also test volts at my o2 sensor while it was plugged in to the car running (i exposed the wires).

only one of the white wires read any volts when checked against ground. (was around 5 volts)

i've checked all my vacuum lines and connections, they all seam ok,

Ive tried a second jetronic ECU from another 92 turbo, nothing changed
I put a new ignition switch in, nothing changed:

Could i have bad wiring to my 02 sensor? if so how do i test it?

townsends page said to check the ELCD system, what is this and how do i check it?

what else could it be?


any help/advise is good help/advise

best luck
