Hello fellow supra fans,
I have already posted this question on mk2 (yahoo groups) but I just thought that I'd go ahead and post it here too since I still haven't been able to solve the problem.
I need to pass smog and I can't because I am having a problem with the timing check connector on my '84. When the connector is shorted, nothing happens. The smog guy tells me that what is supposed to happen is the idle is supposed to change, the timing is supposed to retard and the check engine light is supposed to come on.
I have tried shorting the connector both before and after the car is running as well as before and after the ignition is turned on. The check engine light never comes on otherwise, so there are no trouble codes stored in the ECU. I have replaced both the O2 and TPS sensors, I have used a multimeter to check the connectivity of both wires coming out of the connector itself [one to the ECU and the other (ground) to the intake manifold], and I have checked and tested all of the fuses and relays.
I am really lost here as to what to do next. I don't have a load of money or patience to deal with a mechanic around here. Keep in mind that I am in California, so there's no way that the smog guy will let this little problem slide. I had no trouble passing the emmisions test or the visual inspection. This is the only thing that is keeping me from passing. The car runs great otherwise and I'd hate to have to give her up.
If I am missing anything or if you know what I could try next, please let me know.
Thank you,
Dan
