Oskar is running better with a good amount of Iso-Heet. It's running smoother but isn't completely fixed. My grandfather seems to think it has an exhaust leak, so obviously I'll check that too, considering inspection should be relatively soon. Still think it has a vacuum leak so I need to look for that too. Anyone know how much it usually is to have your car hooked up to one of those machines that sends water vapor through your vacuum lines to look for leaks?
