We have emission checks annually. My ‘95 911 failed the first two years, spent $1000 each year for my mechanic to get the numbers barely above passing. A Mech that works on older cars (356s) said to run a full tank of 91 ethanol-free gas through it. Refill again with the same and then make sure it is nice and hot and then get it checked. Passed with flying colors for the last 4 years. I know, completely different engines, but it’s the cheapest thing to try for a Pre-ethanol car. YMMV, I know mine does.
