Track light My car jerks forward terribly right when i first take off because the track light comes on saying "trac off" this isn't caused by me turning it off, it just turns on randomly.. hasn't done it in a long time, then i had my tires rotated and it started back up (as I thought it would).. when that light is off it drives normal.. any ideas on how to fix this or what might be causing it?

number 4 misfire check either plug or coil --as to jerking if vehicle is not running correct [misfire ]it will not drive smooth trac light --it can be related to the misfire or check abs and brakes and power braking will set off traction control and puts a strain on brakes and c/v axles

Power for the brake lights go thru the turn signal switch before getting to the light bulbs.
Do you have power in and out of the brake light switch and the turn signal switch ?

I can't tell for sure not knowing what the check engine light is on for. When it comes ,on it means the computer has detected a problem with a sensor, or with the emissions coming out the tail pipe. As you described the car lurches forward when put in gear, I would highly suspect the IAT (Intake air temperature) sensor. It is located in the air snorkle, coming from the air filter box to the throttle body. It has only 2 wires going to it, and It is generally caused by bad connections at the sensor, or a broken wire going to the sensor (quite often in the connector body itself). It would be best for you to have the check engine light code scanned. You can usually have this done at a large auto parts retailer for free. They range from P0110 - P0114. If so it is very unlikely to be a faulty IAT sensor, usually wiring related.

I comes on and off when ever I start the

the trac.control is disabled if the check engine light comes on repair the engine problem and the trac.control should work

check the inlet hose for the air from the air cleaner assembly to the throttle body.there is a sensor mounted on the hose.make sure the sensor is not loose at the base or a poor seal.it can be sealed up with silicone .there may also be a crack in the hose flex part.a vacuum leak in this hose will cause the traction control light to come on and erratic running.when torque is applied,the engine moves, and a leak appears.
this problem fools alot of mechanics into checking the abs and traction systems.

I can't give you an explanation for why the car is telling you to check trac. control but i can try to give some help on maybe fixing it. Try - turning on the car, turn the traction control off, turn the car off, turn the car on. Then turn the traction control back on and push the system check button. That should i guess "reset" the trac control system.

Now the noise from the front right of the car is MOST LIKELY the air compressor pumping air into the bags. (i own a 97 Continental but i've never had a problem witht the trac control)

take it to a shop and have them run a diagnostic on it so you know for sure whats wrong whether its the trac control or the transmission

You may have a bad sensor on the steering shaft. Scanning the Body Control Module (BCM) should tell that the sensor is bad.. Replace worn or shorted sensors or components.The lights will turn on if an electronic oproblem is detected but the ECM

Trac is the control that doesnt let your tires spin when they are not making contact with the road. Just by having your emergency brake on will light up the trac light. It also come on with your abs. If you driving on a slick road and you jam on your brakes and the tires slide a little mine will say low track on my car.
