Help spark plug change gone bad
So i changed my plugs and plug wires on my 1998 f150 4.6 v8 tonight... And not it runs like crap. Rough idle and when i turn off the motor i hear a wheezing sound coming for the engine. I checked the boot and plugs to ensure they were all on and tourqed. The plug are tourqed to 100 lb in. Im at a loss it was idling slightly rough before the change but nothing like this.
Any ideas before i drop money on taking it to a shop would be greatly appreciated.
Thanks in advance

Update
Ok folks update here.
So i checked and rechecked everything firing order plug tourqe intake system and nothing...
So i go and ask the guys at oriellys and there was an oldtimer that asked me what plug i put in it. When i told him autolites he said get the crap out of it and put motorcraft in.
At this point i am willing to try anything. Low and behold file is smooth and wheezing sound stopped. I will take a longer test drive in the morning but for now it looks like it really was the plugs.
