Rough idle / surge / no boost
Just purchased a 2000 ssei w/ 107k miles. Car did sit for 2 years however. When I start the car only when its warm it idles really rough for a minute or so, sometimes with a surging idle which causes it to stall. I press on the peddle there is an extremely delayed response sometimes, other times it starts surging even worse. The car also doesn't seem to have the get up it should. I haven't really gotten on it that hard, maybe 3/4 throttle, but I noticed the boost gauge has never gotten above 0 psi. Any sort of suggestion to point me in the right direction would be great. Thanks.
