Is it good idea to replace all 6 fuel injectors?

I had to decline the recommended replacement of all 6 fuel injectors since the cost estimate was about 2k, which is more than the car is worth.

What happens if you have a bad fuel injector?

Meanwhile, an injector that is leaking internally or stuck open will result in an engine that runs rich (too much fuel). Your car’s engine must receive the proper amount of air and fuel for complete combustion.

What causes a fuel injector to leak over the engine?

So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.

What to do if your fuel injector is clogged?

Once the injectors are clogged or restricted, an injectable solution will need to be introduced into the system. Fuel injectors do often contain a small filter which is easy to replace if the injectors have become clogged, which is much cheaper than replacing them.
