And as a quick version...had an emissions light on...was going to get the MIL eliminators, but it went away after a couple of tanks of gas, so I assumed it was a bad tank of gas. THen I changed my oil for the first time today (went to 5W30 Mobil 1 from 10W30 which the previous owner used...had a spare case in my garage....used 6.5 quarts) Any ideas would be appreciated as well, but I'm sick of that light controlling my life and would like to be able to see what it is telling me, regardless of the problem.
