Fuel Injection Cleaner
I read that Chevron Techron Fule Injector Cleaner is a good product.
Do they sell this in Chevron gas stations?

There are two types recently.
Shell 93 gas is blended with it in the Northeast US.

The bottle says it may be beneficial to repeat this treatment twice in row.
I did not add any fuel treatment for 1-2 years, Should I repeat?

If your car is rough are you throwing any codes or need to change your intake air filters? When was the last time you replaced your spark plugs?
I replaced the following:
Fuel filter: Jan-15,2011
Oil and filter change: 26-Mar-2011
Spark plugs change: 26-Mar-2011
So, after this current tank is also finished, should I put in another bottle of this Techron at next fill up?
