too high of an idle, I would think would be the least of your worries, I would check to see if you T.B.I gasket isnt sucked in or blown out, they are notorious for this and can cause hi idle conditions, yes it is computer controled , based on imput sensors to the E.C.M. and than outputed to the idle air control valve, this is a valve mouinted to your tbi unit and has a pintle that moves in and out to obtain correct idle , air leaks , etc, the best way to check is with a scan tool and monitor Iac counts , if they are high, than the computer is telling it to be high, if the counts are low and the idle is still high, the computer is telling iac to slow down and something else is causing high idle ... good luck on both problems, I hope to hear you didnt crack anything detromental.
