When you notice a loss in power while stepping on the gas and when there is a gas leak from injector seals or injector you can expect that its time to replace the fuel injector.
Your car manual would tell you how many miles you should get before the fuel injector should be replaced. Remember to get the seals rings and holders also replaced along with the main fuel injector system. A fuel injector that is not replaced in time can cause damage to other parts of the car such as fuel.
Every time you crank and run your car the fuel injector will be used to provide the engine with the power it needs to perform. The fuel injectors on your car will typically last between 50000 and 100000 miles. The length of time that the injector lasts has a lot to do with the type of gas that is used in the car and how often the various fuel filters are changed.
If one fuel injector is bad should I replace them all. It is quite confusing when youre faced with a situation such as this you get stuck between changing all the injectors which would cost more or just change the faulty one. Its a dilemma situation for many drivers not just you.
A similar situation is when an ABS sensor becomes faulty. There are at least four ABS sensors in a car and when one fails it. The fuel injectors on your car will typically last between 50000 and 100000 miles.
The last thing that you want to do is ignore the warning signs that the fuel injectors need to be replaced due to the damage it can cause your engine. As a recap one of the culprits for the misfiring engine is a faulty fuel injector. You may need to replace it if it is found to be bad.
A car generally has one fuel injector per cylinder. So the question is if one fuel injector is bad should you replace them all. It is better to take your car for a thorough and professional fuel injector cleaning every 30000 miles to ensure that you dont have to replace it sooner.

When your truck starts to white smokeblue smoke and miss and carry on the injectors need to be replaced or new tips installed granted the injectors are only 35 bucks a piece at your nearest parts house. Basically you need 45 lbs per hour of fuel per HP. So the formula above is Flywheel HP 5 lbs 8 cylinders duty cycle in this case 80.
The 57 injectors are rated at about 30 lbs per hour with the 58 psi fuel pump. The 61 injectors are about 34 lbs. Duty Cycle is the KEY factor in the equation.
Answer 1 of 7. Hi Joseph Replace or clean them only if necessary. Or just leave them alone.
The cost to replace them might drastically drain your bank account. There are some things to consider. Follow car manufacturer recommendations.
Determine if the injectors are affected by contaminatio. Clogged injectors can usually be repaired if you catch the problem quickly. Sometimes a fuel injector is completely clogged because of years of neglect or a lack of regular engine servicing.
If this is the case then a refurbished replacement may be the only option. If the fuel injectors cannot provide the right amount of fuel to the engine then the car will run into problems each time it must ignite or combust. Running into starting issues and performance issues like staggered acceleration are common when fuel injection system problems arise.
Noticeably decreased gas mileage. Failing fuel injectors will produce noticeably diminished fuel efficiency or lowered gas. Should you replace your common rail injectors after 100000kms.
We have proved many times over that injectors just arent as delicate as originally thought. The mere act of restoring cleanliness and lubricity to injectors confirms their durability. Restricted If a fuel injector becomes restricted from clogging even if it is as little as 10 of the entire aperture the airfuel ratio in the engine can become lean leading to what is known as a lean misfire.
This is when either the amount of fuel or the amount of air becomes off ratio making the fuel harder to ignite and combustion difficult. If you dont want that either install a oil vent tank or relocate the breather line. Injectors in our 24vs dont usually fail but they do wear to the point where pop pressure will be significantly lower.
When that happens they should be taken into an injection shop and shimmed. Costs me about 230 CAD to have it done and have them pop tested. Joined Sep 3 2003.

Never seen it done quicker then 4 hours heard of it taking a few days. One reason is that if youre going through the effort of removing an old part 176k miles old putting the same part back on isnt usually the best idea. Another reason is that sometimes injectors fail due to debrisgrit in the fuel system which means your other ones are on their way out.
Especially if youre paying somebody to do the work. If not its a matter of how much your time is worth to you. Th average injector lasts 150000 - 200000 miles for a decently maintained truck.
If it were mine and it had more than 150000 on it Id change every injector on the side of.
