Expertise
I take questions about domestic Chrysler-product front wheel drive cars and minivans for the years 1982-2000 based upon my experience and shop manuals. I don't have detailed information (e.g. manuals) nor expertise for Jeeps, trucks, SUV's, import vehicles, or for years more recent than 2000. I am available to take a question between 8AM CST and 9PM CST . If I am shown as "maxed out" try again later in the day as I add question opportunities one at a time so as to respond quickly, but I do have other responsibilities as well so may not be available for several hours at times. Try at 7PM CST as I will always be available for one question then. There are answers to hundreds of Chrysler questions at your finger tips: click on "view past answers", one of which may be to your question as well; or put a few key words in the "search for" box, above.

Experience
I have been a do-it-yourself auto hobbyist for 5 decades, and most recently have been concentrating on the various Chrysler Corporation domestic front wheel drive cars and vans. I have shop manuals and wiring diagrams for many models for the years '83-'00, as well as rear wheel drive cars for the early 80's. I enjoy analyzing problems that other Chrysler enthusiasts are having and sharing my information. Organizations belong to Group co-moderator of the Yahoo autos group The Chrysler LeBaron Club

Question
QUESTION: 2000 cirrus 2.4LT. 165.000 km car runs great but about 6 months age when driving steady at about 70 to I'm hr. the car hesitates had a tune up done transmission oil replaced even had the motor mounts replaced by a mech. that told me the old ones needed to be replaced thats why it hesitates $375 later he was wrong so we replaced fuel filter and the Idle air Control relay but it still hesitates,and if you come to a sudden stop it fells like it wants to stall,it has stalled a few times but it starts up wright away we did a diagnostic test and it showed no problems every thing was working fine

ANSWER: Hi Felix,
I would take a look at the function of the exhaust gas recirculation valve which is located in a small pipe that connects a line from the exhaust manifold to the intake manifold, near the throttle body. That valve could function well enough to not set a fault code, yet it could cause a stall when slowing down to stop. It is bolted into the pipe. It has a vacuum line attached to an electrically operated solenoid nearby.
But the item you want to check is the valve stem, located between the valves round top and the body of the valve bolted into the pipe. The stem is hidden a bit by a flange that is between those two parts of the valve but look inside the flange for a rod that has a circumferential slot. That is the stem. You can put a screwdriver tip in the slot and move the stem back and forth. An internal spring will help to close the valve. You want the valve stem to return to that closed position positively, to a dead stop. If it isn't doing so or seems sticky in its action then spray some penetrating oil like WD-40 on the stem where it enters the valve body, then work the stem back and forth until it move well and closes positively. That may be the answer to your problem as if the valve sticks ajar it will lean out the mixture and cause a stall like you describe. It will also cause a stall/hesitation if you step on the gas when cruising at highway speeds.

QUESTION: Should I replace this part, thanx for the quick response

Answer
No, I wouldn't replace this part unless it seems to have failed mechanically. My experience is that periodically you may find it advisable to lubricate the stem as I described. At some point the inside of the valve may be clogged up which even that can be removed with a wire or wire brush. So try the 'action' of the valve stem and see what you find.
