Make sure you didn't mix up a spark plug wire.

i think you have a loose vacuum line, check the parts that you took apart, or the area that you were working on for a lose hose

I didn't find a loose hose, but i think i'm gonna replace the vacuum hoses within the next couple weeks anyways. I started it, the idle is kind of rough, the engine runs pretty well when i'm driving it, i get good boost, but haven't tried to engage the second turbo because when i hit the gas, the oil pressure guage rises almost exactly at the same time and speed that the rpm gauge rises. i'm not sure why this would happen...it starts out at about 60psi, then if i hit the gas it rises to as much as 115psi. Maybe i didn't tighten the oil filler neck enough? idk, anyone have a clue?

check the map sensor hose...

The cars at home right now, I'm gonna check the maps sensor friday, then i'm gonna replace all the hoses with silicone ones and ties, that way i can recheck all the sparkplugs, make sure the wires are in snug, replace my torn throttle body/uim gasket, and if there are any air leaks that will fix it also, so my next post will be a week from today........
