I own a 2000 Chrysler Concorde with 2.7L engine. Just recenly my car stopped shifting past 2000 rpms while driving. No matter how fast I go the rpms will not go past 2000. It also hesitates, or jerks when accelerating. Any ideas on what the problem is? I had my car scanned and was told I needed new speed sensors. Had these replaced and car is still having the same problem. Please help!!!

Im not sure what road speed you are traveling at but when the engine can't breath it won't be able to rev. See if you have an exhaust restriction (the cat).

i second the cat converter, even though i have seen the sensor do some really crazy things. the car is six plus years old. you didn't mention the miles on it but if it's not over 85,000 there is a secret warrenty that covers the cat converter. call a chrysler arbutrator (i know i spelled that wrong) and find out. thats all the info i have.....hope this helped....vandragon

Suggested Repair

The owner later reported the fault was a timing belt missing teeth, which caused the engine to jump time. Before that, replies suggested rescanning after the speed-sensor replacement and checking for a restricted catalytic converter.

Conversation Summary

A 2000 Chrysler Concorde 2.7L would not rev past 2000 rpm and hesitated or jerked under acceleration. Replacing the speed sensors did not fix it. Replies suggested confirming which speed sensor was replaced, rescanning for codes, and checking for exhaust restriction from the catalytic converter, including a possible Chrysler catalytic-converter warranty. The owner later said the car was fixed after finding a timing belt missing teeth that had jumped time.
