Just wondering that fuel filter and injector cleaner stuff you pour in your gas tank really works....my filter is fairly new but I'm sure my injectors aren't perfect anymore, I just turned 38k miles.....

 

For about $5-6 you can get Redline SI-1 or Chevon's Techron (not Progard) from Pep Boys. They work pretty well to clean up the injector but don't expect miracles.

For $20 or so, I've heard that BG 44K is real good. It's what pros use. It's a drop in the tank bottle.

However, if your injectors are real dirty, you might as well have a mechanic clean the injector for $60. They connect a canister to manifold's vac port to clean the injector and then drop a bottle in the tank. It's not a bad deal by today's high gas price standards.
