rollingthunder1994 Posted January 10, 2005 Report Share Posted January 10, 2005 Hello all, question for anyone, I have a 94 STS whenever i let it sit for 2-4 days, the start it up. It runs a little rough and it smell like it's burning rich for a few minutes, then it smooths out. Do you all think it's time for a tune up? I brought the car in April. The person i brought it from said it was recently tuned up, but who knows. Or do you think it is just carbon built up. I know these engines are built to run. But i must confess i baby this car. The car never failed to start and it runs good. It's just that 2-4 day res period when it runs alittle rough at first, and then everything is okay.
