Has anyone actually used this cleaner and has it removed DI valve deposits? Just curious...
I did try this in my DIT Forester and it seemed like SOMETHING happened, but I don't have internal before/after pics.
I went ahead and tried it because the plugs I had replaced during the LSPI recall (at 40kmiles) looked fairly dirty.
I tried to spray it in past the MAF sensor with the airbox open and did not do a good job, as I had to clean the MAF the next day to get the car running properly. Everything went fine during the application and my daughter did not have to do anything to keep the engine from stalling. After the 1 hour soak, the car belched big plumes of white smoke for a while...but the car also hesitated severely twice AND I got a nasty ball bearings thrown in a coffee can sound when that happened. Had some hesitation issues for a day after that until I cleaned the MAF sensor, now the car is running great. Not sure if the nasty metallic sound was due to the cleaning or the dirty/fouled MAF, I never want to hear that again!
I guess I would have to figure out how to spray it into the throttle body if I wanted to use this cleaner again, I had a stupid idea about pulling the MAF sensor out and spraying through the opening for it but realized the car will probably not run very well with the sensor hanging out in free air!
I figure the massive white smoke must have meant something got cleaned, as I did not see it during the initial application (it was not just the cleaner itself being combusted). I have no proof of that supposition, though.
