From the last time I tried with the engine running and spraying carb cleaner everywhere and causing a big mess. I did not really see a big RPM difference, maybe I was doing it wrong, maybe I was expecting too big a change and moved on too quickly, but nothing really came from it. I still suffer from a periodic hi idle (1500 rpm), sometimes it idles fine at 800. If it was a vacuum leak why did it correct itself and sometimes idle at 800 ? I have since removed the AAR and even swapped out the MPS with another one, no difference. Stock 1.7 FI
So the discussion for today is what is the proper method, tips and tricks to perform a good vacuum leak check.
I am tempted to make a DIY homemade smoke machine from watching youtube to blow smoke in my FI system and check it that way ??
