Car: 88RX, currently has a 3 prong throttle position sensor, with 3 wires coming out the side, going into the wiring harness.

 

I threw a japanese donor engine in there, it came with a 3 prong TPS* with no wires coming out the side, also note that the donor engine was probably an automatic.

 

Is there a way I can make this work, or any better ideas. I almost positive this is why the car sucks so bad right now. Its been sitting for a loooong time. thanks guys.

I would have reused the stock intake manifold.

 

Sounds like the manifold you have may be from an '86 car.

 

Still have the old manifold laying around?

I did reuse the stock manifold

Can't you use the old one with the extra wiring. Won't it just bolt in??

hmm, let me say this more clearly. I have the original manifold, and TPS on the car. That TPS is a 3prong with another set of wires coming out of the side(3wires, going to the wiring harness).

 

From a manifold which I do not have on my car, is another TPS which is the same, except for the wires coming out of the side, so If I put that one in, something somewhere would not be getting information.

 

I am open to any other suggestions to get this TPS problem fixed, buying a new one is out of the question. I just want to get my RX driving like it used to.

 

thanks

pics would help dearly my friend. I have like, a million intakes from NA MPFIs and turbo MPFIs so I can help ID something if need be, without you pulling it all apart on your car.

The 3 wires on the TPS itself are for the TPS signal. The 3 wires that come off the side to a seperate connecter are for the idle switch. I may have another one of these TPS's laying around here... but I'm going to guess that since my integrated TPS/idle switch 4prong unit on my Spider intake didn't work, that neither would the 3prong unit you have.
