Saw this service is available at dealer...uses intake pressure equipment system. Costs $129.
Has anyone here used this service for intake valve cleaning? If this just goes through the injectors, then it's not going to be any good for DI intake valves. I know the DI cars are prone to deposits there. Yeah..I know about seafaom..so let's just keep *on topic* with this system.
Thanks...

 

I have not tried it but doesn't sound like a half bad deal, whatever makes the longevity better of our vehicles

Attention:
GM does not support cleaning injectors on any engines that are not listed in this bulletin. Engines other than the ones listed in this bulletin that diagnosis indicates having restricted injectors should have those injectors replaced.


Looks like it's not for LNF..DI application.
