Any you guys familiar with the fuel saver package offered at Monroe? They said my car needed it and it would restore much hp and save gas. Amongst other things they claim they do, they hook up an "I.V." to the car and it supposedly cleans the injectors. They said it was on sale and I can get it for $80. My owners manual doesn't mention it as a part of routine maintenance. Have you heard of this? If so, does it work and is it worth it. I don't have $80 to throw away.
