Going to do this in a few and have 3 questions.
1. If cleaning do you have to use compressed air (I have no access to it). Will MAF or carb cleaner work?
2. Do you have to replace the O-rings if just cleaning them?
3. I was going WOT and car lost power/shuddered and idled rough, I turned car off then on and all was fine and no codes, I am guessing Vanos.
