idle screwed up
ok, so my problem is when i turn on the ignition the car starts fine and idles at about 1200 rpm and the oil pressure is fine
but...
after i drive it about 5-10 min. the idle drops to around 500 ,and the oil pressure starts jumping up and down, and i had the car stall on me at a stop sign at one time
and i just had the engine rebuilt not even 2 miles on the rebuilt engine yet...
what could be wrong (i rebuilt it myself and it was my first ever engine job ive doneim 16, so maybe i did some mistakes)(hope not)
does anyone have any clue as to what could be wrong i need to pass emitions after tomorrow so i need to do something real fast.
thnx.

i have a 2.8v6 mpfi 5 spd manual.
when i rebuilt it i changed the crank,bearings rods, rings, oil pump, cam bearings lifters ,dist. ,clutch, pressure plate , had the heads and clutch flywheel rebuilt. took me almost a year what can i say.....
i did some checks and i dont have a vacum leak (anymore) so my idle is at about 7-800 rpm...
but i found a new problem aswell, my fan doesn't want to start rotating so my engine reaches over 105 c after 10 min. after which i turned it off. i checked my relay is fine..
and when i connect a jump wire trough the relay with the relay diconnected the fan works. also the temp. sending unit on the left hesd is ok
i suspect the ECM but i need more input
