I think my tps connector is bad...

I have had a lot of idle problems on my 87 TPI Camaro..305 Engine..

Today I was going to check the TPS voltage. It is a brand new TPS sensor.
I put a jumper fire from the terminal in the middle and measure with voltmeter between that one and ground..I got around 0.54 to 0.56 volts..

If I just touch the tps sensor wiring harness a little bit with my finger the volt goes up to 4.5volts...and then I mean just a little bit with my finger...I guess this is affecting my driving because when engine runs and car shakes from driving it would affect the volts??..

Don't you think I should replace the connector??..

 

Going to chime in on this one, should be good

 

yep I would replace the connector. The voltage should not hop around when you touch the plug.

 

I have tried to change the TPS switch and that worked out okay...The TPS switch was new but somehow I have manage to destroy the metal pins inside the TPS so I guess they were touching (short ground) each other..

My car works better now and I have about 0.56 volts on the TPS at IDLE..
