Fuel Injector Cleaning

[Overdrive]

Ok JFP, I'll ask the follow-up question here, just out of sheer curiosity:

If someone brought to you their very poorly maintained Boxster, after striking them with a rolled up newspaper, would you likely use this treatment on it to cleanse the fuel system?

Not exactly what you are asking, but a better option IMHO

Why don't you remove the injectors and send it for a proper cleaning?

In the past I had used RC Engineering (about 4 times, different cars) and had excellent results, they clean the injectors on a ultrasonic tank with a solvent solution, back flow them and flow balance them.

Perhaps you can find a closer location that offers a similar service

You will end with a very smooth running engine, last time I paid about $22-24 per
injector.

Gilles,
This is great… I did not know this service was available. I have purchased new injectors for rebuilds but did not know someone would clean and analyze old injectors at such a reasonable price. Thanks!!

Injector cleaning and refurbishing firms typically do a fine job as long as they are good, and local, otherwise the car is tied up for several days, which is why they don’t work well for shop’s unless they are both very close and offer quick turn around. Otherwise it is usually cheaper to just replace the units with rebuilds or even new.

First, I never hit customers, even the ones I don't particularly care for, with rolled up newspapers or anything else; bad for the shop's image.

Use of this type of system would depend upon the issue involved; these cleaning systems are designed as a "last resort" type cleaning, but will not do anything for an injector with a mechanical issues (bent or pitted plunger or pintle, damaged seats, broken return springs, bad seals, etc.), or electrical problems (connectors, wiring, dying solenoid, etc.); it is designed to clean gummed up but otherwise fine injectors. Quite often with an underperforming injector, it is not dirt that is the problem; it is mechanical or electrical fault which requires replacing the unit. Because the materials of construction change with injector vintage, some injectors do not like to be exposed to the concentrated solvents used in these clean outs, plus the system does not clean just the suspected problems injector, so using the system because injector #3 seems dirty results in #3 being happy, but injectors in #1 and #4 now leaking because the solvent attacked the internal seals. This is why I suggest using these systems sparingly and only when nothing else works, you could easily end up with with an unintended result.
