David it sounds like maybe you might have had your ECU go bad, but I'm not sure.

No , no joke ! a leaking gas cap can cause a code for the evaporative emissions system and turn on the check engine light . This EVAP system stores fuel vapors in a charcoal canister that the PCM - engine computer will purge at certain times . But that doesn't happen that much . Most of the time it is other componets That cause the leak ! Plus there are other thing's that will turn on the serviced engine soon light ! Your vehicle can set hundreds of DTC'S - diagnostic trouble codes . If the light is on there has to be codes stored or a problem with the instrument cluster . Your best bet take it to the dealer !

If you have a traction control light on or an abs light on the all wheel drive won't work right. All the wheel sensors and speed sensors have to work right.

FOR ONE THING CHANGE MECHANICS ! HE SHOULD HAVE FIXED THE PROBLEM, YOU MAY HAVE A SERIOUS BRAKE ISSUE ! IF LIGHT IS ON IT WILL NOT PASS INSPECTION ! YOU MAY HAVE AIR IN SYSTEM, NEEDS BLEED ! FLUID COULD BE CONTAMINATED , NEEDS BLEED OUT, REPLACED W/ FRESH FLUID ! ABS REQUIRES THAT THE REAR BRAKE CIRCUIT OPERATES BEFORE THE FRONT BRAKES, THIS PREVENTS SKIDDING, THE PURPOSE OF ABS BRAKES, CORRECT ? MASTER CYLINDER HAS SEALS, CONTAMINATED FLUID AFFECTS SEALS, BRAKE LIGHT WILL STAY ON UNTIL PROBLEM IS RESOLVED !!! REAR BRAKES IF SHOES NEED ADJUSTED, CLOSER TO DRUM ! THIS WILL HELP, BUT BLEEDING OUT ALL BAD FLUID & AIR IN SYSTEM IS PARAMOUNT !!!!!! BRAKE LIGHT SWITCH MAY NEED REPLACED, PROPORTIONING VALVE WHICH SEPARATES FRONT FROM REAR BRAKES , IS OUT OF BALANCE, THE VALVE NEEDS TO BE @ A NEUTRAL OR CENTERED POSITION, COULD BE STUCK TOWARD EITHER BRAKE CIRCUIT, MORE FRONT THAN REAR, UNDERSTAND ? THINK I COVERED YOUR ISSUE, PLEASE RATE MAY ANSWER ! THANKYOU,

the coil packs are bad,start it at night and open the hood and look for sparks

If it is a V6 fuel injected then either your injector heads and fuel lines may be clogged, go by a container of cleaning fluid for your injector heads, not the one for fuel lines. The one for injector heads will clean both. just pour it into your gas tank and let it sit for five mins then start your vehicle and run for five more mins. Let me know if this solves your problem.

Why bother buying something with a problem?
Get the owner to take it with you to a transmission shop and get their take on it and potential cost. Then get that knocked off the price if you really really want to buy it. My advice is that there are thousands out there, why buy a dog?

Could cost between $1400-$1800

If you open up the hood you will notice that there is a screw holding in the lens from the top. After you take that screw out there should be a sliding lock mechanism on either side of the lens. Pull those up and it will release the whole lens. Pull it out, replace the light and then put the lens back in.
