Hi, Guest
Check for VAC leaks.
At the back of the intake, there is a rubber tube going from a hard line on the side of the engine. That hose sometimes colapses and gets a hole in it. It is for the PCV... if that is busted you'll have all the same symptoms. check ALL vac lines, but this is my #1 suspect.
Also... Good time to also examine and check PCV and boot around oil separator...
