-No apparent leak showing from DIY smoke test. (Does system need to be pressurized?)
One random drive I was randomly hitting decent boost, then never hit again. Which made me think the boost solenoid was acting up the whole time. Replaced it, but did not solve my issue.

*Currently after all those fixes, I still have rough idle, and no boost.

My LTFT seems a lot better?
Do you think my MAP sensor needs to be replaced? I've read it could cause lean issues although I have cleaned it thoroughly.
Could it be coil issues? Spark plugs? Although my issue is a lean code?
Thanks  |
Hello Canadian fellow!
Decent compared to your other logs but still horrible unfortunately. It looks like it's taking a while to build boost and won't go past 10.
Have you taken a look at your Wastegate Actuator? Or have you been hearing weird rattles? I suggest you take a look at it and even connect a manual vacuum pump directly to it and see if you can actuate it.
I used to be Stage 2+ and randomly during last spring noticed that my car was slow. Took a log and I was way off boost. Could also hear weird rattling when I let of gas. I checked the usual chargepipe and other connections for major leaks but nothing. Next step was to test my wastegate but I didn't even need to. Quick peak at it and well I'll le the pictures speak for themself.
I hope for your sake that the actuator is not rusted off like mine, because it was near impossible to change while not removing anything major. Or maybe I just suck.
