New to the site. My 2005 has been burning a lot of oil. I have already come across the air cleaner problem and the fact that they just burn oil.
The real problem I have is from a dead start and then WOT the car will jump up then drop to nothing and back to WOT. I didn't look at the tach but I am guessing around 1800-2400 then 600 and back up and down. It also seamed to do it from a smooth 35 mph, and going WOT just didn't feel right ??
Drives fine for my wife. (Light foot)
90K miles 3.6 L RWD
No codes show up with my Accutron reader
Bad fuel pump wouldn't show so fast I don't think ??
fuel filter ??
Throttle position ??
I will post a Video if it will help.
onlygm, I have a 06 STS V6, 48k. Was burning a quart of oil every 760 miles under Cadillac test. There test is they change the oil, I drove 2000 miles. Under warrenty the piston rings were replaced. Done some reseach and found out the new piston rings are not the same and have a differant part number. 30,000 miles later uses no oil. Unless you rering the engin, buy stock in oil. Danny
