Chrysler Repair: 01 lhs: idles rough when warm

Question
After engine warms up, my 201 chrysler lhs idles roughly and is hard to start. Any ideas?

Answer
Hi Jay,
The best approach is to seek a fault code number which may be stored in the engine controller.
Turn the ignition key: "on-off-on-off-on and leave on" doing that in 5 seconds or less elapsed time. Then watch the odometer window to see the mileage reading be replaced by a 4-digit number(s) preceded by a P. Let me know what you find and we'll go from there.
Please read the PS (below) and respond to it.
Thanks,
Roland
