dealership fuel injector cleaning

has anyone ever taken there truck in and had the dealership clean the fuel injectors? I am having a problem with mine right now and wondered if anyone had done this and what difference did it make? Was it worth the money?

Re: dealership fuel injector cleaning

I've seen it done outside a dealership and they tell me it improved performance quite a bit, back to factory spec anyway.

I would think that it would be better to first run fuel injector cleaner in the gas tank a couple of tanks before spending some monely like that.

What kind of problems are you having with your FI?

Re: dealership fuel injector cleaning

I have ran injector cleaner through the tank a couple of times and have not seen any change. I am having a hard start problem both hot and cold and the engine is running rich. I have checked or replaced everything. The O2 sensor, fuel pump is less than a year old, checked all of the ignition system, timing, ect ect. The only thing that I can think of is that I may have a leaky poppet valve and cleaning the injectors might help.

Re: dealership fuel injector cleaning

I've had the service performed on one of my Toyotas and it worked great. The idle was rough and the cleaning smoothed it out really nice and got rid of a nasty sputter on acceleration. With this service, they disconnected the fuel line and hooked up a special canister and ran the engine for a half hour or so until the canister was empty. In my experience the off-the-shelf bottles of fuel system cleaner don't do anything to a vehicle that already has issues. It only *seems* to keep it clean if it's already clean. I'm not sure how much the service is on Chevy's, but it was $99 and money well spent.
