This light has NOTHING TO DO WITH MAINTAINENCE, what it means is that a malfunction has occurred in the electronic fuel injection system or the engines electronic emission control system, there are well over 200 such faults that trun this light on,when the light is turned on a fault code is set in the memory of the computer that controls the system, to find out what this code may be you must have a shop test the system, this is called an OBD2 fault code test, you may also have it tested by any Kragen or Autozone Parts store for free in most area's. This willgive u a code but not any info oon how to fix the problem that turned on the check engine light, for that u need a qualified technician

The gas cap dets wet and the light comes on

I just had a similar problem with a mustang.. The baffel in the gas tank had broken loose.. So the gas would slosh around the tank.. I could hear the baffle in the tank moving when i would go around corners.. WHEN I WOULD MAKE A RIGHT TURN THE ENGINE WOULD DIE.. ONE OF THE THINGS THE BAFFEL DOES IS KEEP THE FUEL PUMP SURRONDED WITH FUEL WHEN CORERNING..

Ford Mustang service engine soon and check fuel cap lights are on

Check fuel cap light will not immediatly go out upon replacement of the fuel cap. Might take several days. You could go to a local autoparts store and have them read the trouble code (for check engine light) and reset it. If it was indeed the fuel cap the light should stay off after resetting it. Most autoparts stores do not charge a fee to do this.

A wrench symbol came on in my 2005 Ford Mustang what could this mean

The wrench light is NOT the check engine light! It is a failsafe warning light and usually when it comes on there is a problem with the "fly by wire" throttle. The wrench light will not be caused by leaving the gas cap loose. You could try disconnecting the battery for a few minutes then reconnecting. If this is no help you have no other choice but to take it in for service.

Engine and tire light stuck on

The easiest and cheapest thing to do is disconnect the battery for at least 60 seconds. This will reset the computer and should reset the lights.(NO this dosn't harm anything except you will have to reset your radio stations) Most of the time it can take a day or so for the lights to go out once the battery has been disconnected.

Misfire on 3

Misfire on 3 could mean bad plug or bad wire...or the distributor cap has a bad spot in the 3 position. Time for a tuneup. Get all new cap, rotor, wires, and plugs. Should be around $100.
