Fuel injector symptoms for bad, faulty, dirty, clogged, or leaking injectors are :
Leaking Injectors will cause:
- Increased Fuel Consumption
- Poor Idle
- Fuel odors inside and around the car
- Hard Starting
- Poor Emissions
- Oil thinning, which can lead to catastrophic engine failure
- Hydro lock, which can lead to catastrophic engine failure
External injector leaks is a fire hazard and can not be fixed.
Injectors leaking externally due to a cracked body must be replaced.
Fuel injectors are resilient and does not often need replacement. Before you buy expensive new or refurbished fuel injectors let us help you take care of your fuel injector problems. Our OEM approved ultrasonic fuel injector cleaning service is the only injector cleaning method that will guarantee reliable results. If you ship your injectors to us for cleaning we will return your cleaned injectors back to you within 24 hours after we received them. We will not charge you for our time spent on the injectors we were not able to restore.
Diagnosing a clogged injector is not always easy because it acts the same than a bad coil, a broken spark plug wire or a bad spark plug. One or more cylinders are not firing.
Old fuel, carbon and residue inside the fuel cause fuel injectors and or their filter baskets to become clogged. A fuel injector is considered to be clogged if the amount of debris or gunk inside the injector or filter basket has built up to such an extent that it does not allow fuel to flow trough.
Once the injectors itself or the filter basket becomes clogged no amount of intake or fuel rail induced injector cleaner will resolve the problem. The only and most effective way to deal with a clogged fuel injector is to remove it from the engine and have it professionally cleaned.
Dirty Fuel Injectors:
Fuel injectors are considered to be dirty when the hydrocarbons and additives which all forms part of today’s fuels, together with engine gunk and carbon, cause the injectors to become restricted. Fuel injector flow rates, atomization and distribution are affected and this can cause all sorts of drive-ability and performance problems.
Although there is some quality “pour in fuel tank” injector cleaners that might help to keep your fuel injectors in good shape the only true and tested way to clean fuel injectors properly are and have always been to do it outside the engine and with the proper cleaning equipment. This process is inexpensive and has saved people our customers thousands of dollars.
In most cases dirty fuel injectors does not have to be replaced with expensive new fuel injectors. Your old injectors can be reconditioned to operate at the same level as new ones.
Faulty fuel injectors:
Fuel injectors are deemed to be faulty if they do not operate as designed.
Clean Fuel Injectors:
Fuel injectors are considered to be clean if and when fuel delivery, atomization and distribution are within 1% of the design specification of that fuel injector.
Bad fuel Injectors:
The coil is bad (resistance is out of spec or none existent)
Broken Pintle, ball or disc
Broken Return Spring
Bad Pintle or Ball seat
Pintle or Ball seized to the body (Rust etc.)
Leak in the actual injector body
The injector can not be recovered.
We do not charge for the time spent on bad fuel injectors.
