It means your transmission is slipping, that happens in a lot of mercury mystiques.

How to know your automatic transmission is working fine


Auto. Transmition when giving trouble will not change up until R.P.M. has gone over 2500 rpm. Should should change up between 2000 and 2500. When changing it down (pushing accelerator to the floor) it should do this imedietly. Isuzu Troopers have a power button on the console between the front seat's this is for trailer pulling and when it is on.(power light on in Dashboard) then it takes more R.P.M. to change up allowing for trailer weight.

2000 accord v6 engine idle goes up and down after start up


I am having the same issue after I changed my battery today. Upon doing some research it seems like there is some way of aiding the computer with proper idling. I haven't done it yet... plan on going to the dealership where I got the battery, but from my understanding you disconnect the negative line from the battery for a few mins, reconnect, and then apply gas at 3000 rpm for a few mins until the fan kicks on. AND this will help reset your car to proper idling. Good luck

Idle too high on a 06 cobalt


when you clean it make sure that you hold the butterfly open so you can get the spots clean that need it. If there is anything in the way the butterfly will not close. Just a small bit of dirt will do this .

98 Cavalier 2.4L engine stumbles at 2000-2500 rpm


Could be a short in the wiring for the O2 sensor.   I currently have the same issue only my car finally threw a code after two days of it acting up.  Code 106.  Changed the MAP sensor and it now throws 108, MAP sensor high voltage circuit.  Ah the joys of cold weather and broke down vehicles.  But I know that you wont always get a code with a short.  Let me know if you fixed the problem.
