Motor magazine July 2003 has a excellant article on finding vacuum leaks using a general purpose smoke machine. According to the article they run between $1,000 and $1,300. A little expensive for the backyard mechanic but affordable for any professional garage. If you have vacuum problems and take the car to a garage make sure they use a smoke machine to check for vacuum leaks. Dave Sontos vin 02573 [Non-text portions of this message have been removed]
