Default 2005 pt cruiser

I just replaced my crankshaft position sensor and my camshaft position sensor.
When I first drove off after replacing them. The car ran great. 10 min later it was missing up again. It bogs down when I excellerate. Just like the codes said. I changed the sensors. Is there a chance there's a wiring problem. The car runs great when its cold. When it warms up it start doing same thing it did before. Is there a chance there could be a bear wire or something that's causing this. Anyone had anything like this????? Let me know.

See if the wiring to the crankshaft sensor is rubbing on the half axel.

I will do that. thanks. I don't know what else it could be. It has to be a wire somewhere.. That's as good a place to start as any. Maybe I will get lucky and that will do the trick

Never had this problem with a PT, but...

Does the problem actually come and go with the engine getting up to temp? A friend had a Jetta and those were notorious for having bad temp sensors. The car would run great cold, but when it got to closed loop, the temp sensor was all over the map and it was hit and miss.

Open loop is generally rich, it also might be something making the car prefer to run rich. The ultra-gauge and most of the scanners should tell you if the car is in closed or open loop. I would keep an eye to see if that is where the car falls on its face.

Of course, first you should check your wiring. That is always a good idea.

What are all the engine trouble codes?

Have you reset the codes with an OBDII Scan Tool and got the same codes to come back?

How many miles do you have on it?

Has the wiring harness been repaired previously from the crankcase, camshaft to the PCM?
