Okay guys, I’ve exhausted all my research and I’m completely confused as hell now on my issue, where to really start, troubleshoot and how to actually narrow it down to what it is.
A few weeks ago I did a pull in my car (because turbo of course.!) and my check engine light came on. Went and got it scanned at autozone and it said there was a wastegate actuator solenoid malfunction. Tried to do some research on it, read somewhere that it could be the BCS was shot. Can’t find any anywhere online to replace it.
The current issue I’m having with my car is confusing because, I don’t know if it’s my BCS or if my wastegate is possibly stuck open (or closed, even?) Driving the car normally I don’t have any real issues. Boosts fine at 5psi and 10psi. And just normal cursing on level roads my gauge is reading -10psi (vacuum).
Here is my concern. When I’m driving down hill at all (regardless of speed) and when coming to a stop, my gauge reads -20psi (vacuum), and when I really let on the gas to full boost (15psi) it’ll get up to 15 psi, but only hold it for a few seconds it will begin dropping to anywhere between 11-14, sometimes gradually from 15psi to 10. A few times it hasn’t even reached full boost and only gets to 10psi.
On top of the positive boost issues that I’m having, when I give it the throttle there are times that the car seems like it isn’t even doing any acceleration! (the RPMs will go up, but the car hardly accelerates when this happens. Which hasn’t happened ALOT but is still happening nonetheless.) I don’t think I have a boost leak because that’s the first thing I thought of when I first experienced this (haven’t bought a boost leak test tool yet, but it’s in the cart. Just waiting till pay day or taxes come in.) and checked all of the lines and hoses and they all seem to be fine.
Where exactly should I start other than the obvious blt (when I get the tool)? I can’t track down any replacement BCS’s at the moment and I have no idea to find out if it’s the wastegate/actuator.
My car is completely stock other than a turboXS BOV. Thank you in advance my friends.!
