I was told by my smog only station was to add the Techron and fill up the
tank with gas.
Then drive it until you need to fill it again.   Fill it up with gas and
then take it in after a
1/2 hour drive.     Whether or not this helps I'm not sure.   The 85 caddy
I was driving to do
this ended up needing a new cat and 2 mufflers.......

I'd say try the chemistry experiment first and then replace the more
expensive items if
you have to...
