Were the spark plugs oil fouled? If so it can be a valve cover gasket, oil would be leaking into your spark plugs.
they are overtorqued.
To my knowledge, Cadillac will not be producing the Cadillac DTS for the year 2012. The Cadillac DTS will be replaced for the 2012 year with the Cadillac XTS. Hope this helps!
The "DTS" as in Cadillac DTS stands for DeVille Touring Sedan. The Cadillac DTS replaced the Cadillac DeVille. The Cadillac DTS was first produced in 2005.
Absolutely not!The last generation of this model was produced between 1993 and 1996 and it was the largest production car made in the USA.It was replaced in 1997 by the d'Elegance trim line of the Cadillac DeVille.Ultimately,in 2006 the Cadillac DeVille nameplate was replaced by the Cadillac DTS,the current flagship of GM's Cadillac luxury car division.
yes there are aftermarket solutions for this
check that your sparkplugs are not cracked and that your wires are fully on your plugs
Valve seals If the oil is on the top of the plugs, there could be valve cover plug tube seals to change.
If they leak, break or stop dampening the ride
locksmith or have new locks installed
we would need more information but most if not all bushings can be replaced
Located n the fuel tank.tank has to be dropped to be replaced
How about the plug cables? Check connections at distributor and harness, and they should generally be replaced at the same time as the plugs.
