Replaced crankshaft position sensor but still ran just as bad, maybe worse. Disconnected battery, ran good for a day then back to bad with check engine light on. Goes on and off but still shows code for crankshaft position sensor when the light is on

Yep, the sensor is not the problem, the computer is telling you the camshaft is not in the correct position while the engine is running, here is a guide to help you fix it.

The code for my 2001 PT cruiser is P1391. Changed crankshaft position sensor-not fixed. Cleared coats using OBD scanner. Ran good for about a half day then back to bed and check engine light coming on again

The P1391 code does not specifically mean the new crankshaft position sensor is bad. On this Chrysler system, P1391 means the PCM is intermittently losing either the crankshaft position (CKP) signal or camshaft position (CMP) signal. I would replace the sensor pigtail and then clear the codes. Here is the part for $15

let me know what happens.

It is not bad, just align the wires with the new connectors and cut the wires to match them up. make sure the connectors are orientated the same. You can use crimp connecters, should work just fine. Let me know if you need my help.
