Howdy, from AZ. I'm new here. Need to know how reset my pcm?? Just bought a 2004 Town Signature CREAMPUFF / 102,000 miles on it.. Programmed 2 new key fobs and the car went nuts. First rough low idle, then HIGH revs, back to low rough, HIGH, low, etc. No brakes, shuts off. BEAUTIFUL CAR needs help !!! Thanks to all.
 
You can reset the PCM by disconnecting the battery for ten minutes, but that's not going to be your problem.
You most likely have a major intake (vacuum) air leak, probably between the intake and the vacuum booster, but it could be elsewhere too.
 
You are RIGHT Sir !! Found the pvc hose going into the intake cracked, almost broke off. Brittle from the heat.
THANK YOU SO MUCH..... F I X E D !!!!
