Question question: i just removing smog and a/c

well i just got done removing the smog and a/c and plugged the 2 vacuum lines, and when i started my car the first time it stalled, but the second time it was fine.. it also seems to kinda idle a little lower, but once i drove it around the block and turned it off and tried to start it again, it started right up but had a little hesitation like if it were to stall and but it didn't.

any ideas?

The EGR vacuum is fed off of the upper intake manifold. Cap the vacuum source on the upper intake and you will not have a leak.

The exhaust gas ports on the back of the heads need plugged. You said you plugged the tube instead of the heads, make sure that bolt is sealed and not leaking. Also, I hope you plugged the tube coming from the H-pipe that feeds exhaust gas to the cylinder heads.
