Question about 1994 Toyota Pickup
Can remove oil cap or vacuum hose engine will idle down and run smooth. When it is surging the exhaust burns my eyes. When I remove a vacuum hose the exhaust is fine.
Sounds like an Idle air control valve or a positive crankcase ventalation valve(or pcv valve). use some intake cleaner in the air intake and take the pcv valve out and shake it it should rattle and move freely. mike
