My gf has a 2001 Subaru Legacy GT. It's a great car but lately we've been noticing that the acceleration has been dying down a bit. For example, before we could punch it and it would fly on the highway. Nothing like a Porsche but good acceleration. Now we have to floor it for a while (12+ secs) just to get it up to 60-70mph. My dad said to put a bottle of injector cleaner in the tank because the fuel system might need to be cleaned out. We grabbed a bottle at Wal-Mart, but I'm not sure if she added it yet or not. My question is, if the bottle doesn't do the trick, and provided there are no wierd noises or fluids coming out of the car, what might the reason be for the noticeable decrease in acceloration? Thanks! -Emt1581 Wanna kill these ads? We can help!
