1996 Chevrolet 1500 Pickup Question: i have a vacume leak around my intake,is it the intake or what

Yes, it is most likely the gasket under the t-body! Idle speed to high?

Misfire cylinder# 2 possible low compression,, plug or plug wire this needs to be repaired first! Intake gaskets not known for vac. leak, check PCV circuit and 4x4 vac. circuit if 4 wheel drive you did not post! Good mechanic with a real scanner can find your trouble.

ya i could be wrong on the code its a 2 wheel drive i just gave it a complete tune up .all msd cap rotor wires ,plugs also,and as i recall the code was a miss fire but also said possible due to vacume leak,which i can hear without even opening the hood,
