hey guys i just bought a 93 civic dx it was converted to stick and swapped with a d16z6 well bought it for $400 of some kid and it was smoking like a crop duster so i pulled the motor and the rings were fried prob from the straight pipe exhaust he had on it so i traded the exhaust to some dumbass for his stock 96 ex one. I rebuilt the motor we bored it 40 over shave the block and head and port and polish on the head so i put it back in and it would warm up and stall out so we adjusted the throtle cable for now to get it running. well it revs up and down when i hit 1500 rmp and is fine before and after that someone said clean the iac so i did still does it and i also don't hear the vtec pop and the gas mil sucks. im just trying to find the prob before i blow it up cuz its my daily driver i don't have anything els to drive thanks for any help.
