So I was driving my rx7 the other night and was climbing a hill and progressively losing power til the car stalled and cut off by itself.

After it sits for a while it can turn on (pretty rough start) runs for maybe 20-40 seconds then cute off.

I decided to check my TPS. With the car on but not started, voltage at tps would range from 1.3 to 4.6 based on throttle position.Or vice versa on the other wire.

Does this mean my TPS could be bad and if not what other things could it be?

Please help.

 

out of gas?
which way are you testing the TPS?

 

S4 or S5?

 

It's a 10th AE so s4

 

It's not spark because I can start it, not fuel got that, so I would think it's something with the throttle being that it starts and idles rough and cuts off

 

afm good?

 

Check your thermosensor amd verify it has a good connection and is getting voltage (this is the sensor on the back of the water pump)

 

fuel filter.

 

If the car dies while idling, then leave the key in the on position and see if the main relay is still in the closed position or not. To do this measure the B/W wire in the check connector near the lead coil which has 3 or 4 wires as it should still have 12 volts. Also, measure the B/Y wire at either coil as it should also have 12 volts.
