Hi Forum,


This is my second technical querry - the first was answered very quickly and accurately - vacuum leak fixed to brake booster.


I am moving on with this winter project - this 97 XK8 starts and 'hunts' while idling (stumbles, revs up, smooths for a moment - repeat). During the speed transitions, I can hear clicking - I believe it to be the VVT selinoids? Should I hear them click?


Anyway, just pulled codes, cleared the codes, then pulled them again (without turning on engine). I get P0123 and P0223. (I also get P1000, but I think that indicates that the car hasn't been driven since last clearing?)


The jtis says that the two p-codes have to do with the Throttle Position Sensor. Sure enough, when trying to verify the connectors, I see that three of the four wires that go to the connector have pulled out (quite possibly my fat hand fishing around for vacuum lines). The black wire is still connected. I searched jtis, but I cannot seem to find wiring diagram and connector diagrams.


Can someone direct me to the proper pinout of the TPS? Looks like I will need to solder the wires to the connector and try to clear and collect codes again.


Thanks!
Jamie
