so i replaced my spark cables, spark plugs, ignition cap and rotor. car was idling fine except when started cold when it would die a few times before staying on. i replaced the IAC and fixed that. the thing is one of the heater hoses started leaking an didnt notice it seems some of the hot radiator water splashed to the ignition and spark cables and now am having a lot of misfires on idle or while revving and also noticed that the intake is making a very loud not normal hissing sound. i replaced the throttle body with the iac the thing is that the throttle i installed doesnt have one of the vacum lines that the old TB had. i mean the vacum line at the front. i dont know if this is causing all this. but i would like some help. also could a faulty tb gasket be causing this? the one i used was in bad shape
