you guessed it, the tune up did not fix the problem. that was not really a problem for me because i know things. i was able to figure out my new old car had a vacuum leak at the number one cylinder. i could fix it myself for $23.00 (the cost of the gasket). this repair is a bit of work, so i got a price from a real mechanic, and the price was $400.00. the big mechanic book that real mechanics have, says it should take 4 hours to make this repair. so, here is the deal; there should be another book for guys who think they know stuff
