Changed the plugs and wires on my 2000 Explorer and now I have a horrible popping noise coming from the intake area. The plugs and wires are tight, so it isn't arcing that you're hearing. Could I have pulled something else loose getting the old wires out? I'm clueless but I need to get it fixed. Thanks.

Got it; nevermind. The manual I was using (Haynes) had the plug wires and cyl #'s all wrong.
