Either a vacuum hose leaking , or a bad intake manifold gasket. Spray engine cleaner directly onto the intake manifold gasket while running. Spray good and if you hear a difference in the idle, that is the problem. Also spray all vacuum hoses. This is the easiest way to check.Good luck, let me know how you make out or rate this solution

Possible vacuum leak at EGR or PCV, or even at the intake plenum gasket is where I'd check first...accordianman

SOURCE: 97 chrysler concorde 3.5 bad accel off idle , ok on high end

check your air intake control switch: it is on the manifold and, is attached to a flap inside the intake; this switch's flap should be easily moved by the air from the aircleaner and, tells the engine computer that you have the right amount of air coming into the engine for fast acceleration if it fails the engine computer will not know the amount of air available to sustain rapid spark speed lastly check the installation of your air filter I have seen very dirty ones and, some inserted upsidedown there is an arrow that should point to the engine

SOURCE: 97 chrysler concorde high idle around 2k in park

if anything is the out of position the least bit there would be a code thrown and you would have had a check or service engine light come on. not knowing if you have checked that or not,there could be several things it could be. without knowing all things you have done I dont want to start throwing things out at you to replace. that could get expensive.

It may be caused by a vacuum leak, make sure to check all your hose for cracks and/or hoses that may have popped off

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.

High idle o n a 1996 chrysler concorde. have change the tps and the idle air control valve. i think its a vacum line but i dont know which one. which one s effect the idle


High idle is usually caused by a vacume leak. First place to check is the cold air intake manifold. All hoses, throttle body, and sensors. Throttle Position(TPS), Mass Airflow(MAS), Idle Air Control Motor (valve) IAC. Controls Idle speed

A malfunctioning throttle system can cause both a high idle as well as an engine stall.

A dirty air intake or cracked air intake tube is often the culprit.

High idle 1300 rpm chrysler concorde 3.5 1995 after i changed 6 injectors


If the injectors are OEM for that motor then it sounds like your idle got knocked off or was adjusted to compensate for the old injectors getting worn and clogged. Look for you throttle cable at the intake manifold. Where the swivle is for the cable there is an adjustment for the cable. It should be a little round nut or screw.
