Default Fuel Injection

I'm tryin to figure out if buying a brand of fuel injection cleaner from the store for like 5 bucks, is the same as paying them to do it at Firestone for 100. They say they do it differently and it takes a week to clear the **** out of everything. Suggestions?

well, technically, using the liquid fuel injector cleaner is only a temperary fix, when the holes in the injectors start getting gunky it reduces the spray pattern and can cause you to run lean eventually. I just went through that problem literally days ago. I had bought new sti pink 560cc top feeds but had to wait a week to get installed so i used the fuel injector cleaner for one tank and it helped for the time being but as soon as i refilled my gas tank with no injector cleaner i noticed a difference in throttle response and felt like my power didnt match how high my revs were. Id say either A. have a reputable mechanic give you either a full tune up ( spark plugs, fuel injector cleaning, ect) usually its best to change them all at once since they need to be maitenced at the same time, i think its 120,000 miles. or you can always get new injectors or have your stock ones modified to have a higher CC flow rate. Im pretty sure you get better gas mileage since they will be running at a lower stress %, ive been getting 5 extra miles per gallon since upgrading my fuel pump with a walbro 255l and sti pinks.. hope this helps
