Over time, your vehicle’s fuel injectors will need cleaning. Contaminants in fuel will clog the injectors partially or even completely in some cases causing poor performance and fuel economy. When this happens, you need to have them cleaned or clean them yourself.
Symptoms of clogged fuel injectors include:
- Poor fuel economy.
- Poor acceleration.
- Engine hesitation.
- Increased emissions.
Treatments For Clogged Fuel Injectors
Fuel Tank Additive
This is the cheapest way to deal with clogged fuel injectors but is only effective with slightly clogged injectors. You will add an additive to your fuel tank, fill it up and drive it normally. The additive will contain strong detergents that will clean your injectors as you drive your vehicle. In tank fuel injector cleaners are readily available at auto parts stores, gas stations and grocery stores. Expect to pay about $10 for a bottle of cleaner.
Check prices on fuel injector cleaner.
Pressurized Fuel Injector Cleaner
If you have some automotive skills, you can look into using a pressurized cleaning system. This type of cleaning requires that you disconnect the fuel system and hook up a can of pressurized cleaner to the fuel rail. This method is not highly recommended because the high levels of cleaners and solvents can be damaging to other engine parts.Expect to pay about $30 to $50 for a pressurized cleaning system.
Off Engine Cleaning
This is the best method for heavily clogged injectors. Your injectors will be removed and then professionally cleaned off of the vehicle. A shop will need to handle the cleaning of the injectors, but you can save money by removing them yourself if you choose.Expect to pay about $40 per injector for cleaning. This price does not include labor costs for removal and installation.
Fuel Injector Replacement
This is the most expensive method to cure clogged fuel injectors and is in most cases, not necessary. If your injectors are extremely damaged though, this is the rout to take. Expect to pay $100 to $200 per injector for replacement, not including labor.
