Injectors issues

Does the car have problems starting? Low or poor car idle? The engine does not reach full power or RPM? Does your car die, stall or lose power while you are driving? Is your engine misfiring? Is your car leaking fuel or do you notice a strong smell of petrol in your car? Do you notice increased fuel consumption?

If you are experiencing one or all of those symptoms, your vehicle is very likely to have a common fuel injector problem. You came to the right place!

  1. Dirty Fuel Injector Problem. An injector is considered to be dirty when fuel residues together with engine gunk and carbon, create a build-up that restricts the fuel flow rate, atomization and distribution of the fuel through the injector. This is a common problem and it happens periodically on all vehicle makes, regardless of age! We have even encountered this problem on a relatively new 2013 Mercedes C-class injector.
  2. Clogged Fuel Injector Problem. Fuel Injectors can clog from the build-up of foreign objects, most commonly rust. This is normally the case if the car has been sitting idle without maintenance for a long period of time. Should this be the case, the injector will not be capable of supplying gasoline to the intake manifold.
  3. Fuel Injector Does not Open or Does not Close. Fuel injector Leaks. If the injector has a faulty spring it might not open and thus allow fuel to circulate or it might not be able to close- causing the injector to leak gasoline.

OUR MOBILE DIVISION, THE INJECTOR REMOVAL SERVICE CAN ASSIST YOU ON THE ROAD!

There are situations in which a diesel injector cleaning job will not fix a broken injector. Don’t worry! Our vehicle repair centre, as well as the mobile mechanic service, have a stock of genuine injectors purchased directly from the manufacturer that can replace your existing one so that your car drives smoothly again and that you don’t have to worry about an injector issue in the future.

WARNING! A lot of the injectors get stuck and hard to remove due to carbon build-up, corrosion and electrolytic reaction between metals. Although most of the OFFICIAL DEALERS and also a small number of GARAGES can service a bad injector problem, 99% of them will NOT be able to help if the injector is stuck. This requires hydraulic hi-tech equipment that is very expensive to cover most vehicles. This means that:

  1. Because they cannot remove just the injector alone, they will need to take the whole engine apart and replace the parts (cylinder; head) that keep the injector stuck in place with new ones;
  2. You will have to cover all the costs associated with purchasing new parts and labour (up to £3,000) which in some cases can write the car off;
  3. You will not be able to use the vehicle for a significant period of time until the work is completed.

OGS MECHANICS and its division, INJECTOR REMOVAL SERVICE are London’s injector removal specialists, our latest hydraulic equipment allows us to do the jobs that others cannot. Therefore, if you have a seized injectors issues, we can save you at least a few hundred pounds from having your engine dismantled and the cylinder head replaced.

Here you can see how we use our Hydraulic Injector Removal Tools to remove a stuck injector:

Top signs that you have a fuel injector problem:

  1. Inconsistent or Abrupt Engine Power. An inconsistent fuel supply can cause a car to fluctuate between low and high RPM, making the engine to deliver power in chunks, rather than smooth.
  2. Engine Misfires. This happens when the fuel injector is clogged most of the times, therefore there might be a second or two when the injector might miss out to supply fuel when it’s expected to, so the engine’s performance will be compromised. Should this be your case, the engine requires immediate servicing before causing other damages related to overheating and pre-igniting the fuel mixture. We would even recommend making a booking with our mobile service in this case to reduce the risk of an engine breakdown on your way to us.
  3. Rough Idle (Uneven Engine Idling). Surprisingly enough, a problematic fuel injector will also cause problems not only when you are driving, but also when the vehicle is running idle. Instead of running smoothly, because the fuel supply is not constant or powerful enough, the engine will be rough and irregular.
  4. Leaking Fuel. As mentioned previously, if the injector is stuck open, this will allow fuel to leak – instead of being sprayed. The fuel then flows in the manifold in the form of drops weakening out the engine’s efficiency and making it to lose power. This can sometimes be smelt even inside the car.
  5. Reduced Gas Mileage. A faulty fuel injector will allow fuel leakages either through cracks in the body or broken internal springs. Therefore, your vehicle will waste fuel, every time you turn the engine on.

Much to our surprise, 3 out of the 4 fuel injectors came out in one piece, but as you can see there is a lot of corrosion on the injectors due to the ingress of water, corrosion is also visible on the electrical part which can short-circuit the injectors.
