What happens to the fuel injectors when they go bad?
Two things make injectors bad, they get plugged up which can be fixed or they go bad internally or electronically and this cannot be fixed. Injectors that are shorted or bad electronically must be thrown away. The real problem is when injectors are subjected to “hot soak”. This occurs after you have driven your car and the motor is fully warmed up, then you shut the motor off and let it cool down. During this cool down time, any gasoline residue remaining is being baked on the injector tip. The miles driven between “hot soaks” is the difference between having to address an injector problem at 50,000 miles or so and being able to double that mileage. Consequently, someone who drives 100 miles then shuts the car off (which equals one “hot soak”) is much less likely to have injector problems than someone who stops and turns off their engine 10 times in the same 100 miles. If you insist that your injectors are cleaned, by far the best way is to have them removed and cleaned and balanced by
