Hey guys/girls, so first things first im new here so my problem MIGHT have been solved already, it would be great to get the answer sooon though

Basicly, my problem is this. I have a 2001 DTS it started out running great but then it started over heating (needle passes center mark) and the car would start smoking..smelling alot like burning oil/coolant.
Got that fixed after changing the thermal stat and it started running normal again
However, the car still smokes, the smoke smells somewhat like coolant and the coolant level IS infact going down. Along with the coolant going down the oil slowly does too. :hmm:
And NOW the check engine light came on, as the car stops too, you can feel a slight misfire so though came in..we changed all 8 spark plugs with brand new bosh platnum 4's..yet we can still feel misfire and check engine light is still on :helpless:

Some Questions!!
First of all, is it normal for t he car to run with the temp. Right in the center?
Secondly, does anyone have ANY idea whats going on with my car and how i can fix, or reduce this problem?

THANKS , i know its alot to read but it will help me TONS

Some people fall for hype, others stick with what consistently provides good service.

2001-DTS, Please go up in the black bar ^^^ and study the entire Cadillac Technical Archive. Then go a tad lower and read the FAQ in the narrow blue bar. Then go down to Discussions: Engines; Technical Tips and read through all 9 pages of posts. Practically every question you may have is already answered in there.

Depending on your driving habits (all city, slowly) and if you overfill the oil (past the halfway mark on the dipstick), the engine can consume as much as a quart of oil in 600 miles. Some members get 1,500 miles, some get 3,000, some 4,500; depends on the engine, the driver, and the usage.

For some insight into year 2000+ Northstar parts and ignition systems, go up to Albums ^^^ and click on mine - the red 2002 STS.
