Lack of power!!

I have finally gotten the idle problem fixed and the timing is on 0. Problem now is that when truck shifts to 2nd gear I notice a lack of power and then it will pick back up. It never did this until I rebuilt the dist and put it back in. Should I advance the timing? How would I go about it?

No mention of a model year or engine size...that would help alot in determining the correct timing. There should be an emissions sticker on your hood or radiator support that has this info too.

93' GMC 4x4 w/5.7. It shows the timing but it still doesnt seem right.

0 with EST Bypass disconnected, right?

yea I unplugged the wire to set it. not sure if it is in timing or could be something else. not showing any codes. fuel mpg is still down quite a bit

With the EST connected, the timing should be around 20 BTDC with the engine at idle. What is yours at?

If this was not the case before pulling the dist, I would double check all connections and vacuum lines to make sure everything is hooked back up.
