I have a 90-91 Crx Si with an ls swap. The car is running off a p75 that the previous owner wired up.

The car is throwing TPS code but runs perfect. TPS is the only check engine light.

When I change the green and yellow wires, the light goes away but then it won't allow me to accelerate half throttle!

I tried a few other combinations, but they didn't allow the car to run, or did the same thing and not allowing half or full throttle without kicking back.

Which combination of wires did I miss?

Thank you for reading and your help

 

Oh, this is the only check engine light, so I can't attribute the problem to anything else

 

And its more of a stall than a studder..

It just falls on its face everytime at half/full throttle, then when I let off, it will accelerate again.

I had a similar problem a long time ago, and just had to get a new TPS

 

You can check the sensor with the car off.

Put key into ignition to ACC position.
Use a multimeter and check the voltage at the sensor.
You should see ~.5 VDC at idle, and ~4.5V DC at WOT.
As you move the throttle butterfly, the voltage should increase smoothly as you slowly open the throttle. If your sensor a "dead spot" which means you need a new sensor



Yellow = 5V DC
Red = Signal
Green = Ground
