I m guessing some kind of throttle body glitch,I don't know.It has to do it again to investigate further. How many miles on the engine? I highly recommend you pull the intake manifold and check the amount of carbon that has built up on the backside of your intake valves. Direct injection only motors are notorious for carbon build up, and it can cause the intake valves to stick creating all sorts of fun side effects (backfires, misfire with no codes, etc). Maybe do a compression test to ensure the rings are good as well. It sounds like you may have dislodged a stuck/sticking intake valve when you released the negative crankcase pressure (opening the oil cap with engine running). Here is an excellent video: LINK I linked it to the time in the video pertinent to you, but I highly recommend the entire video. |
