CRC GDI Intake Valve Cleaner
Do any of you have any experience with CRC GDI Intake Valve Cleaner? Our 2015 Fit (84,000 mi) has the Ck Eng light on, and the dealer says it's because of carbon build-up. They cleaned the intake system ($300), and now they want to replace the injectors ($1,700). Looking online, this CRC product seems to clean the valves. I'm going to a good local mechanic tomorrow to see what he says.

Dealers I know like the BG induction service. Probably for padding their pockets, but maybe it helps.
Problem is that none of this stuff will help if the problem is that the injectors have actually failed. Sadly, that seems likely since Honda has a TSB for faulty injectors on 2015's.

being that there was a catch can craze here on fitfreak a couple of weeks ago, i was getting ready to jump aboard and ensure that my Fit too, was optimized for a long and healthy life.
so i was going to buy some of the CRC cleaner you listed. i try to research most of my purchases, regardless of cost. i was curious as to where the junk that would be cleaned off the valves would go. ...and came across some information online that stated the CRC may not be so safe to use. ideally you spray the cleaner into a vacuum line, it cleans the valves, the crud from your valves makes it way to the oil pan, and finally you change the oil with the crud in it.
BUT on its journey to the oil pan is where the cleaning method is flawed. though your valves are clean, all the crap that came off them is now possibly lodged between the cylinder and its walls, scoring and scraping them.
unfortunately i think the only way to do it right is have the head removed and have them blasted.
injector wise, maybe you can try a fuel additive and reset the computer. i periodically use the Lucas Upper Cylinder Lubricant in my car. Big bottle at walmart is super cheap.

The Long Term fuel trim also went back to -7% from -1.5%. When i got the car new, it was ard -7% to -8%
Performance wise, my butt cannot tell if there's any difference. My mileage is 25,500km and the car did not have any problem. I figure that prevention is better than cure so i purchased a can to try out.
If anyone out there has experience with the CRC cleaner, pls do give your feedback on your experience.
