So I have a 97 ka24de with a fully reconditioned head, cp pistons, reconditioned rods, new crank/bearings, new oil pump, new water pump, blah blah blah basically a built ka. everything has about 100 miles on it

about 3 days after dropping the engine back in the car it started to bog out at idle. only happens once the car is warmed up and driven. Once u leave first gear the car starts acting normal again. I took out the Idle Air control valve, everything seemed to have been working good, but i cleaned it out anyways. I replaced the S14 MAF and its still bogging out.

what can this be?
 
it could be voltage to iacv also
or fuel pump voltage...
if all other checks seem good
 
this may be a dumb answer but after you replaced the maf did you unplug the battery? maybe your car used to compensate for an old maf and when you replaced it, ur ecu still compensated. try that if you didn't already.
 
are u tlking like when u come to a stop your car dies when warm if u just drop your clutch and let it coast it will shut off

cause if so my car has the same setup and it also does that lol
