Heh, yeah those multipliers can be a real bitch. lol. It's okay, I'm sure I've done it.

A bad TPS wouldn't cause significant issues with the operation of the engine... it's just a trim sensor. Worst case scenario you have a poor idle, fuel economy gets a little worse and your throttle response gets a little sloppy. You can actually disconnect the TPS and should be able to drive without noticing a huge difference.

Measuring resistance of the TPS isn't as reliable as measuring the actual voltage at the ECU's VTA pin. Should be ~.5v throttle closed and 3.5v throttle wide open. I remember from tuning these cars that the voltage should not exceed 3.48v at WOT. Vc should be at about 5v (around 4.8v measured at any sensor location).

I thought I already covered this but that must've been in another thread.
