Re: New problem as of yesterday, where to start?
I checked the vacuum lines and I found a crack in the hose going to the bottom nipple of the waste gate - exactly where it would cause a problem such as the one I was experiencing. So, I checked fluids, drained the catch can, re-lashed the one noisy lifter and took it out for a spin. It wasn't totally warmed up, but it hiccuped under just a little load a couple times, so I decided it wasn't a super idea to get into boost.
Could a bad spark plug or plug wire cause something like this? It's pretty random.
