CPS Issues

[sumter_f-250]

Hey guys. Last week, my CPS finally went in my truck. I replaced it with a used one that my friend gave to me as a spare just incase (thankfully!). So it ran fine until today. I went to go get dinner and came back to the house with no problems. When I went to leave for the store, it didn't want to start up. So I checked the batteries and connections visible on top of the motor to make sure there were no loose connections. So, I figured it was the CPS again. I went to Autozone and replaced it with a grey replacement CPS. When I started it up once installed, it didn't seem to idle right. When I took it for a test drive, it seemed to sputter as if the CPS was going out again....but it's brand new. Any ideas what may be causing this?

Thanks.

Get one from a ford dealer or international dealer,
some of the ones you get from auto parts store are crappy, some people have gone thru sevreral until they got one that worked good from a auto parts store.

You might check the harness connector while you're at it. If you think it needs a replacement:

Camshaft Position Sensor (CPS) Connector (repair connector with 12” pigtails for CPS)
(Ford) 7U2Z-14S411-SA (96-97, also shows WPT-899 on package)

Cheers!
