I gotta quick question. I have a 06 Cobalt SS 2.4 Auto. Randomly my traction control light is turning on and my car is shifting hard as ****. Not in a good way. Then it will turn back off randomly and work fine. I cant seem to figure out whats causing this. I have had computers hooked up to it to see what it will pick up and cant figure out anything. Any Clue?

Here are my mods just in case:
Eibach Springs
Corsa Catback
Header Downtube from CA
B&M Shift plus

Body stuff...grills headlights blah blah blah


Any one have any clues on what could be causing this? there is no ABS lights coming on nothing. Thanks for the help

 

Wheels?...you got the stock or custom.....could be an ABS sensor loose...any work done on the car lately?

 

Yeah mine is doing the same. Right rear wheel speed sensor is throwing the code. Havent looked into it yet though

 

stock wheels....has done it since got the car. only a few times before 50000 mile mark. does it every day almost now. I have had to replace a hub but did it before then....no codes either

 

Take the B&M Shift Plus out of the loop and re-check for the condition.

 

Alright, now I got a code...It says cylinder 4 misfire....changed plugs and swapped coils...still doing the misfire and t/c light. My plugs look burnt around the base of the white part. (Cyl 3 and 4 for sure...didnt take out 1 or 2) The Plugs arent that old. still look good but just have a brown ring around the white base. Throttle body is pretty dirty...not sure if that could throw just a cyl 4 misfire or not. I did have a jet mass air in but I put the stock back...no change. Any idea?

Oh yeah....it looks like the heat from my header has melted the plastic cover over all the wires to my coils....the wires themselves arent burnt..just that crappy black cover.... Please I cant figure this out.
