So is it possible that someone put that thing in my car even though it's for much bigger GM cars? I guess I would have to go to a scrap yard and find a Chevette and take all the vacuums and the switch to put them in my car?

Ok I can get you a copy of the vacuum diagram for your car but I need to know does it have a/c, power steering and manual or a/t transmission.

Thanks! : )

The car is automatic, no a/c, no power steering.

Thanks a lot for the diagram! I have one question though. Is the thing on the right an A/C compressor? (My car doesn't have A/C) : S

I don't get that either as the diagram is suppose to be auto trans with no ac and no power steering. Strange.

Gosh! I forgot to mention that my car is a Canadian car! I guess that's why I kept on finding the 2-3 or 5 ports TVS! I checked on a vacuum diagram website and for Canadian vehicules, the TVS has 4 ports! Now the trick is to find one somewhere.

Yes true.

So. I've changed my switch and the idle smoothed itself a bit (?) Except for the egr valve sticking once in a while, but the torque converter still wont lock-up when the car is warmed up.

It probably the lock up solenoid.
