HELP falling on its face
#1
Exclamation 
hey guys

so the cars been in the body shop gettign the last finishing touches for the big show this weekend it my cars first debut of the season. 1 major problem has arised and maybe you guys can shed some light on this for me

last november i pulled the motor out of the car and such to figure out some issues with leaks. well i never did take the motor apart i left everything as is just replaced a VC gasket and new power steering pump and alti.

fired the car up last week (no exhaust just downpipe) and the car ran and idled awesome. went yesterday and the car idles and runs great until it gets warm (a few mins) then starts leaning right out to max and started to run like a lumpy 5L

changed the plug yesterday and it helped a bit but not much.
vac is a consitent 18-16 psi. fuel is bang on 30 psi, oil varies as the car gets warmer. idles stay around 900-1000rpm. even when the car starts to go lump the revs dont budge which is odd to me

we let it run for a good 5 minutes amd it seemed to be ok so a buddy of mine gave it some gas and the A/F was a good 13.5-15.5 sweep then the second he left of the throttle the car fell on it face and i got ----- across the A/F gauge and then slowly came back up to 14.7ish

car has a hesitation when crusing but the second you give it gas it takes off like absolutly nothing is wrong with it. then take your foot off the gas and it falls on its face

any ideas guys?

iv sanded all the grounds and fixed some grounds, changes my plugs, checked for vacuum leaks. all i can think is o2 sensors possibly?
