so i'm running out of options ... and I still dont know what is wrong !!! VERY frusterating .. and I dont want to do this anymore !!!!
I spent about 3 hrs today on the "check engine" and I'm almost ready to admit defeat ..

I have talked to a buddy of mine (All Toy , in Kamloops ) and he got a rig in there shop , basically with the same symptoms .. he asked me to let them know whats up !!

anyway ..

I got the new/used MTM O2 sensors .. and as I suspected . the wire length is different .. so hence the part # change .. (I guess) installed = NO differance .

checked wire harness integetry between MASS and computer = contenuity OK on all 5 wires . Harness is good .

also checked computer values as per "diagnosis" in manual ..THA + E2 pins .05~3.5ohms @20*C all with in value .
suggest pins are ok .. I didnt get to operating temp. and check values .. lost hope here >

I'm realy lost here now .. and almost ready to give up !!
considering removing the check engine light bulb , and compensating the TPS .. or something stupid like that !!!!
