Mini Cooper S Engine Management Light

The following are descriptions from the Mini-Cooper S owner's manual.

Service Engine Soon "?If the warning lamp comes on
either continuously or intermittently, this indicates a malfunction in the emissions-related electronic systems."

EML light: "Engine electronics ?Malfunction in the engine electronics. You can continue to drive with reduced engine output or engine speed."

Triangle circled by an arrow: "Automatic Stability Control plus
Traction (ASC+T)/Dynamic Stability Control (DSC)
?Indicator lamp flashes: System active: drive and braking forces are regulated.
The indicator lamp stays lit: ASC+T/DSC switched off with button or defective. In the event of a defect: please have the system inspected at your MINI Dealer."

First, inspect the belts to make sure none failed at high RPM. If one broke, inspect any cable or hoses in the plane of the belt to see if there was any damage (e. g., a ripped wire in the ASC+T/DSC system). Second, get a readout of the engine error code. (If you get indications of a major vacuum leak including rough idle, look for a blown head gasket.) If you get something else, please post the results in a comment so we can go to the next step.

I changed the spark plugs and spark plug boots in my 2003, GMC Envoy XL SLT, 6 cyl, 4.2 L engine. Now it starts up smooth but when you turn on the heater or AC the engine idle drops and the engine runs...

engine soon light starts flashing off and on , this indicates a severe misfire which could damage the catalytic converter .There a few different thing's that will cause this .Plug wires , plugged fuel injectors low ,fuel pressure , If the check engine light is on or flashing ,DTC"S -diagnostic trouble codes will be stored .Have it check , most auto parts stores will do this for free ,an be glad to sell you parts .

Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.

(1995 Cadillac Eldorado) - Service Engine Soon light is on.

If this problem just started I would try to get a jump on it. It will be easier to track down if the light just started coming on. Otherwise other problems may come into play and the mechanic will need longer to sort them out. At around 70.00hr.Cheapest fix is to try and drop in a set of plugs. Good luck.
