I have been trying to solve my 15 miles to the gallon problem for quite some time. My frequency valve operates normal, (After a quick drive around the block I hear the buzzzzzzzzzzzzzzzzzz ugh buzzzzzzzzzzzz...) but just recently I have noticed white smoke in the mornings and terrible accleration just after leaving my driveway. It seems to clear up within 1 minuute of runing the car. The smoke only occurs when I give the car gas in 1st gear during this first minute, and it does lag badly. I am not leaking any antifreeze, and the car never smells like gas even though it eats it like it is a bottomless pit. I also have a slight grumble/rattle/scrape/not good sounds bad sound in the engine that I can only hear when I am outside of the car near the engine. This engine has less then 8000 miles on it and was purchased new from houston less than 3 years ago. I mention this problem again only because the white smoke thread just started and some people are experiemceing this accl lag as well. I would like to urge you to see how much gas you are using, maybe we are all in the same boat. The only idea I have is that my CO screw is out of adjustment, but I seem to idle fine, and it seems like a screw that far out of adjustment would idle real rough. Any other suggestions?
