Thanks for the reply. Yeah, it's driving me crazy. I think it's fixed and then out of nowhere, it starts doing it again. Hopefully the new intake will eliminate the issue. I'll also have the other piping checked while I'm there. Hopefully we find a solution.
No not yet...first they blamed the dv relocate so I removed it and nothing changed. I did find the TOP coupling to the intercooler had popped loose, I fixed that and instantly ran better. Was ok for a few days then started doing it again, but very randomly and not nearly as bad as before, and only after it has been driven for a while, aprox 30 minutes or more, and again not always which is what baffles me because its hard to pinpoint it.
I'm monitoring it and hoping it gets worse so they can actually find something wrong lol.
