ok, well i havent driven the car in two months and the last time i started it up was about a month ago. i decided to start the 7 up today, well it started and it could barely idle. Oh its also about 5°F where i am. Seems that when i give it gas, it revs up but the revs pulse on the way up. It also emits a big cloud of bluish smoke on the way up but it smells like premix oil. is it the extreme cold thats doinbg this? i know my air intake sensor is going bad, could this be the problem? thanks -alex
