My TBI is starting to get BAD gas mileage and every once in a while it gives a little hesitation and then goes. I am converting to TPI in a couple of months so I just need to know who suggests what as far as fuel injection cleaners

 

get whatever is at the store but do it on a full tank, doing it on an empty can can eat rubber fuel lines. Have you checked your O2 sensor or spark plugs?

My bad gas miliage was from an old o2 sensor.
