Default Rough Idle, Warm A/C, and Cam Sensor Issues!

Hello all, I have a 2003 Touring Edition, and I have been having a grand time playing detective with some issues. I'm hoping they all point to one fix, but maybe someone can help me out.
In March of this year, I replaced the Cam Position Sensor per an engine code I received about that time. Things were going great, and a couple weeks ago I replaced the plugs and wires in an effort to get rid of some sluggish acceleration. I used Champion platinums, and also replaced the ignition coil, all with parts purchased through my local Car Quest. Since that time, I have yet again replaced the same sensor and STILL get the light and the RPM limit. This is where it gets interesting. I seem to get the engine light only after the A/C has been running. If I leave it off, everything seems fine. Additionally, the A/C air blows warm at red lights and the car shudders very badly.
I took her to the dealership yesterday, and naturally couldn't get the light to come back on, so after tightening a few belts and a diagnostic, I got her back just for the light to come on no sooner than I left the parking lot. I am not anxious to take it back to the dealer, my wallet kind of hurts. Any help would be much appreciated!! Thanks!

Welcome to the forum. First you need to change the Camshaft sensor AGAIN, but this time only use a genuine Chrysler part not an after market auto store brand.

Second, you need to find out if your radiator fan is working on both speeds. That's the number one reason why the A/C blows warm.

What does that mean - radiator fan working on both speeds.?

The answer is quite self explanatory. The fan has two speeds, unless it's a turbo.

It's your first post. How about introducing yourself and say something about a problem your having. Kind of rude to just stick a line into a forum out of the blue.

I had the warm air idle issue on my 2007 a while back and it was the fan. Sounds weird, but if the fan isn't working then the idle gets rough and the AC blows warm when stopped. Crewzin was one of the people that told me about it. He is very knowledgable.

Hello all! Are you still around rfurey15? I am literally having the EXACT same problem with my 2005 PT Cruiser convertible... Replaced the cam sensor and it worked for exactly a week... And, today the check engine light is back on when I turned the AC on... It happened almost immediately. It was 100 degrees today and I felt like I was melting on my 30 minute drive home from work today. I also have already spent hundreds of dollars and REALLY need your help to tell me what you had to do to fix yours! If anyone else knows... I'd greatly appreciate it!

Thanks again!!
