Question about Chrysler Cars & Trucks

Open Question

Why is car idling up and down after I start it, like 20 minutes after driving it somewhere?

My car starts idling up and down, up and down, after I start it when I will be going back home from somewhere. In other words, like if I go to a store or something, I will shop for maybe 20 minutes. Then when I come back out and start car to leave or head back home, the idle is all over the place! 1100 rpm's in park, 900 rpm's in park, 1200 rpm's, 600 rpm's, 1100, 800, 1200, 700, 1000, 600, 1100, 800, etc, etc! Back and forth while in park. And when I put it in drive, with my foot on the brake, not moving, it still does it. When I take off(slowly) it's still doing it, kind of real light bucking a little tiny bit, and it just doesn't take off exactly right, not like it did when I left home, it's back and forth with the surging and stalling so to speak. 1100 rpm's, 600 rpm's, 1200, 800, 1000, 500, you get the point I'm sure. Sorry. It's just up and down, up and down, it's crazy because it don't do it before I leave to go somewhere and it idles like a kitten purring at home before I go somewhere! It's like 10 or 20 or 30 mins after I have shut it off that when I go to start it again, it starts the surging and falling, back and forth. It does have brand new factory plugs and new NGK wires. Its the 2.5L, 1st gen, 2000 Chrysler Sebring Conv with only 94k miles. Thanks for any info! Thx a lot.

SOURCE: 98 Isuzu Trooper stalls on cold start, idle issues..

I had the same issue on my 99 Trooper.

It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.

I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.

They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.

Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor

The total cost to me was $345.00, and I definately don't feel gipped.

SOURCE: 1993 (2.0l 4 cyl) Ford Probe Wont Idle when warm.

Josh, Did you output the car's diagnostic codes before you reset the computer?
Just to confirm: your car has the "FS" engine - 1991cc double overhead cams?
built on the Mazda "GE" platform?
does your car have an "engine check light" or "MIL" on the dashboard? if so where and what does it look like and what does do ? ie: comes on when ignition is turned on & goes out after engine starts. or comes & goes out after x seconds. etc etc
are you 5sp manual or auto trans?

does your car have a diagnostic plug with a flip open lid just behind the battery near the front left suspension tower?

2004 Nissan Altima 3.5L BATTERY LIGHT went on during 15 minute drive. Next day car "died" while idling after a 20 minute drive. BRAKE WARNING LIGHT & BATTERY LIGHT on prior to full electrical failure.


Start with checking the alternator voltage with a multimeter. With the car off check the voltage in the battery which should be holding 12v charged less if flat of course then start the car and test the battery again. If the alternator is good you should be getting a reading of 14 to 14.5 v if it's the alternator it'll A) not put any charge into the battery or B) be a very low voltage being anything under 13.5 v

Engine dies while idling, then car won't start for a few minutes


One possibility is a blocked fuel line or filter. It basically runs out of fuel and you have to wait for it to come through slowly. The other possibility is the ignition system is losing spark as something heats up. You have to wait until it's cooled down before it runs again.

Immediately after I start my '07 Corolla the idle speed is around at 1,400-1,600. This generally happens in the morning or after work. When that happens if I I let it idle for five minutes it goes down...


This idle condition is normal for a cold start, the computer is controlling the idle for proper fuel burn. It is not necessary to wait five minutes for the idle to come down. Allow about one minute before putting into gear and driving.

Car stuck in idle


Trying disconnecting the battery again this time for 10 to 15 minutes. Then reconnect and see if it clears the problem.

1996 Camry 100 km stalling


You have one of two very common problems.
Number one may be a stuck open EGR valve
Number two would be a failing Idle Air Control valve (IAC).
Try this: Open the hood & locate the EGR valve, close to the firewall, behind the intake. Find & take with you a small hammer. The next time that it happens, open the hood & tap on the EGR valve. If it is sticking "open" the tapping may dislodge the carbon particles that are keeping it open.When the EGR valve is open, exhaust is getting into the intake at idle, and this will def stall out the car.
There is no repair to the IAC valve, it would need to be replaced if it is bad.
One of these two scenarios will cure your problem, I see it every day.
