Sounds like you have had a battery go dead or replaced. If that is so you need to have a throttle body service performed.

    My 2002 JGC is doing the same thing. It has had a dead battery recently,and a new battery installed. It ran fine for about 2 weeks then started idling erradically (600-1500 rpms) and then a week later began stalling intermittenly at stop signs. 2 questions...#1 ,what is relationship between having a dead battery, or a new battery installed and the throttle body...#2 how do you perfom a 'throttle body service'? Ok one more. Is a 2002 4.7 a TBI engine?

06 monta carlo LS traction control light comes on but there is no ABS light on.I also noticed that when iam cruising down the highway the car's tac is jumping a little and the car is jerking


Engine misfire ! If you have a diagnostic scan tool hooked up ,a professional grade . Can see misfire counter , which would show which cylinder is misfiring . A misfire would cause your jumping and jerking problem . And this would cause traction control light to come on disabling the traction control .

Check engine light----speed control


Sound like a problem with the vehicle speed sensor; if your check engine light is on, then I suggest scanned the computer to know exactly what fault code is stored there.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.


Thank you for using FixYa, have a nice day.

You need to have the alternator checked. The tachometer runs off signal from the distributor, but can be indirectly affected by the charging system. It may be as simple as tightening the alternator belt, but I would guess that the alternator itself is going bad. Alternators that are marginal in charging ability anyway (old) may just go bad under the load of charging a fully dead battery.

I gave a jump to my 1993 400 sel now the abs and asr dash lights will not go out and the speed ometer does not work


Check fuses, you are not supposed to "jump" MB thats why they have forever roadside assistance. You charge battery while disconnected and reconnect to start.

My speed ometer stays stuck then jumps around is it a sensor or electrical


1) Remove the rear wheel speed sensor from the axle housing.
2) Connect a Digital Volt/Ohm Meter (DVOM) across the two sensor terminals and record the reading.
3) The reading should be between 0.8 and 1.4 k Ohms. If not, replace the sensor.
thanks mate!!!!!!!!
