96 Chrysler concorde 3.5L, I have consistantly pull the gas after start or it won't stay started. As is the pcm forgot the idle. Once its warmed up it will have a rough idle and eventualy die. What...
I have a 1996 LHS, same 3.5L engine, loved the riding and smoothness when i bought it 2 years ago..... F@#$%ng money pit, a POS scam artist of a mechanic charged me 4200 for new front end suspension a year ago which is already shot again, after that i insisted on doing everything on this car myself. As i have no professional training nor do i have a stocked garage this goes without saying is a daunting task.I recommend buying or borrowing(local library) a Chilton and/or Haynes manual. The Chrysler Concorde is the same car different body style as my LHS, a Piece of something.. I'm in the midst of learning about the idling, as i have an opposite problem with too high rpms.
So far, i've concluded that some sensors only malfunction during certain conditions, i.e. cooling temperature sensor that activates fans, also can cause rich or lean fuel/air mixtures. It sounds to me like something is inducing a rich fuel mixture(high rpms) and your PCM (LHS' under air filter compartment) is overcompensating and has stored into its memory leading to a lean running car. I know it doesn't answer your question but hopefully it'll spark an idea. when i figure it out exactly i'll let you know.
