new injectors on 1992 Allante
 

I installed all new injectors, it started right up, runs smooth, but now i have a very high idle. no codes, what could be causing this. I cancelled each cylinder on the onboard computer with no change on each cylinder. thanks. any suggestions??

vacuum leak. min air rate too high. If you block throttle body will engine stall? yes check min air rate and tps. if not vacuum leak.
