Excessive Fuel Consumption after fuel injection cleaning?

sounds like he wrecked injectors...replace them...you may be able to get rebuilt ones

my fav on line store is rockauto.com...lowest prices..i swear it

It all depends on exactly what they mean by cleaning the fuel injectors. If their just going to throw some fuel injection cleaner in your gas tank then NO that is not reasonable and is a ripoff! But if they're going to physically clean the injectors and inspect the entire fuel injection system then maybe it's an ok price but once again it all depends. My suggestion is just go by some fuel injection cleaner at an auto parts store or Walmart and buy two and throw them in your tank, two because it sounds like your car has never received a fuel injection treatment. The two should be good enough. If you feel your car shaking in the morning when you first start it that usually means injectors are dirty. But if you don't feel anything then don't worry about it. Try the injection cleaners first then go back to the garage if your not satisfied. Their really not that expensive about around three dollars each ten dollars for the better brand. It's better than spending ninety dollars and especially if all their doing is throwing some fuel injection cleaner in the tank, which you are more than capable of doing yourself. Hope this helps!

How long has your check engine light been on (how long have you been ignoring it)? That will point you in the right direction as to the real problem of why your fuel economy has allegedly become so bad. It would also run like complete crap if it were running that rich.
