I haven 87 z-28 with a 5.0L v8 in which the throttle linkage kept sticking, so that i had to "tap" the gas to keep the RPM's down. One day after driving for a couple miles i tapped it, and it just fell to crap. The engine now stall if i don't press the gas down, and intially while pressing the gas pedal it will die and then shoot up. I would think these are the symptoms of a vacuum leak. I can not visibly see any holes in the manifold gaskets, and all tubes appear to be in place. The service code came up as 44 which is "lean exhaust". Should i replace the O2 sensor? gaskets? fuel canister? air pump?
