2000 Chrysler Sebring Q&A
2000 Chrysler Sebring Question: Can idle be set too high and cause a racing sound in the engine?
For the last few months, when driving the car, the engine sounds loud as if accelerating constantly. The car has less than 80,000 miles. The mechanic checked everything and reported the car was fine, but it has not sounded so loud and like the engine is "racing" before. - BobbyKayL
Have the wheel bearings been checked? Has the mechanic gone for a TEST DRIVE WITH you , to verify the symptom you are noticing???? - ziptie12
Bobby, my best guess would be that your IAC (Idle Air Control) Valve is acting up. To be sure, you really need to have a shop look at it with a live-data scan tool. Otherwise, just replace it and see what happens next...Idle and timing is usually not adjustable in todays vehicles. - your.mechanic
Bobbykay....If the sound increases as you go faster but your RPM's are not jumping up as well...the problem to address is more than likely the wheel bearings. They will hum louder and louder at increased speeds and can cause some vehicle vibration at high speeds. Fully agree with ziptie, especially since you had a mech. look at it already. Test-drive is to check wheel bearings. - csubak30
I had problems with my 2004 sebring. Sometimes it sounded like the engine would briefly sierge on the xway. At times it would stall at a light. No mechanic could figure it out. I took it to the dealer. It was a MAP Sensor. - knpierce
