EPC Issues

Another cheap option I forgot to share and given that you did your CC not long ago is to use CRC’s Intake Cleaner. A few of us are testing this and have added this to our maintenance regime (every 5K miles). If the cause is a bit of carbon in the flaps making it get stuck or not opening within range, this could help (I can’t assure it but worth a try) to clean up some of the build that you might already have.

As I mentioned it’s not that expensive and easy to do:

I'll have to take a look at that too. Do you spray it into the intake with the engine running? Is there a thread somewhere on this stuff?

No thread that I’m aware off, all the steps are explained on the can, the engine needs to be running at a constant 2.5 or 3k as I recall and you spray in bursts post MAF, basically loosen that MAF hose so you can spray in.

Obviously this will never substitute a carbon clean, some of us are just curious to see what it does... and technically it should remove a little bit of that loose carbon that we should have after 5K, 10K and so on after the initial clean. In any case I already decided that I will follow an every 25K miles carbon clean maintenance schedule.

I use something similar, but I got it from BG products. Its a little chamber that you pressurize and injects a cleaner post MAF just before throttle body. You inject it once the engine is up to full temp and you let it run at idle with bursts up to 2 or 3K then when done drive the bejesus out of the car and not long after change oil. I plan to do this on every oil change as I cleaned valves about a year and a half ago and want to see if this will help prolong the time between carbon cleans. It totally could be snake oil, but starting with clean valves I thought it would be interesting to try and see if any change is noticed.
