2000 Z3 2.0 Sudden onset misfiring with traction control light and EML light coming on. Happened as went over slight bump and noticed an odd smell ?burning which lasted a minute or so. Car starts fine but as soon as throttle is touched the same lights come on and she misfires. Whilst driving the misfiring is intermittent. She sounds perfect on starting up but trouble as soon as throttle used.

It sounds like you have a loose connection or wire somewhere, becuase you stated it started happening after you hit a bump which the jolt would cause movement in a component or wire causing some type of short or mis-connection to happen. I would check all wires, cables for loose or corroded connections, loose ground wires, especially battery and starter connections and tighten accordingly.

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 .

Why does my traction control and eml light come on Bmw e46 ?


I'm sorry Roger but you are going to have to get it to someone with access to the plug in diagnostic unit for Beemers.
there seem to be several things going on but when it coughs up the diagnostic info you may go straight to it?

Ok, my 2000 acura 3.2 tl egine light blinks and the tcs light stays on, also the engine has a slight shake at idle. Took to autozone to get the codes came back as all 6 cylinders misfire, multiple misfire,...


This is strange. The tcs is a traction controll error. If you are getting misfire codes and traction control warnings, then I would have your control module tested to make sure it is not having intermittent power issues to each component.

You must have the traction control system scanned for the fault code that is present when the light is on.

in each wheel you have a traction control sensor that feeds info to the computer. You may have pinched one of the wires. I also had the same thing happen and found that was the answer.
