When I get off the throttle, there's a certain point where the car just jerks forward, after which if i squeeze back on the gas it the car will jerk backwards when I go past that same point on the throttle.

I'm pretty convinced that my TPS is misadjusted (or am I completely off base here?)

Anyway, I searched the web, the archives, and the FSM, but I still can't find the test connector (I can only find a yellow 2 pin connector near the airbox?) and there are many screws near the throttle body, so I can't tell which is the correct adjust screw. Car is running perfectly other than this minor annoyance so I'm afraid of screwing everything up if I turn the mixture or idle screws instead.

Does anyone have any fotos of these items? Google found an article on fc3s-pro.com that looked like it had those fotos, but the site is down!

 

Spot on. Depends if you're using the two-lights method or the ohmmeter method. I prefer the latter because the lights are really just used to set the emissions controls properly. Find the TPS plug (follow the wires from the TPS to the 3-pin plug) and insert the DMM probes into the back of the plug. You want the brown and black wires. Set you DMM to resistance. It's on the front of the TB close to the TPS. If you push on it you'll see the TPS plunger move. Using a screwdriver (and without pushing on the screw) turn it until the DMM reads 1.0 k-ohms. Open and close the throttle a couple of times and check it returns to the same setting.

 

Hmm...OK looked at the parts diagram from fc3s.org, looks like the part that has a black plunger to the bottom front of the TB is the TPS right? With the plunger getting pushed to the left as u squeeze on the gas?

Will go and try to trace the wires from that tomorrow.

 

That's the one, has 3 wires coming from it. The test connector is floating around near the air flow meter area, it's a green 3 wire plug, only one over there.
