Tach sprung to life, most other things were resolved, and more importantly MY TURBO CAME BACK! I had forgot what it felt like! I'm assuming no power to the EGR somehow disables the turbo (even though it's vacum based?
)
What's odd is that the car was not smoking at idle before and now it's smoking a decent amount, as well as blowing out some nice sooty smoke when the turbo kicks in (I missed that too
) But how would the EGR affect anything at idle or before the turbo boost kicks in?
