Looking for the least expensive way of fixing it myself
SOURCE: won't start after intake gasket replacement
ase mechanic here. this has happened to me too, try checking your wiring again, it is very easy to mix up the back three cylinders. and on the coil remember number six is the middle coil. from left to right its 523614

This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck

Sounds like either the intake is still leaking or your head gaskets are gone too. Are you certain it's gas also?
