Help, I have a 2001 pt the engine is missing and sputtering so i put gas dry and gas treatment in and have ran the motor for about a hour with no change. Pulled the computer codes and got codes 1684 and 1391 so i changed out the cam sensor,reset the computer and restarted ran good for a minute and the same two codes 1684 and 1391 cam back. Thanks for any help

Default Re: engine trouble

P1684 does not indicate a problem; it's only a status, which indicates that the PCM memory has been cleared within the last 50 ignition cycles.

Fault Code P1391 Intermittent Loss of CMP or CKP

You replaced the Camshaft Sensor and the problem could be that OR the Crankshaft sensor.

Did you use a Chrysler sensor or from an aftermarket parts store?

It's from o'reilly, but also it seems to get worse when the engine is warm and has ran for a while.
