Interesting Tick
 

A few days ago I replaced my plugs.. had to for the nitrous..went to the NGK TR6 plugs..they are still gapped at .052

But I'm hearing a odd tick when I'm sitting a light.. I know the tick when I first start the car up and let it idle, but I'm in drive and its sitting there doing this..

When I changed the plugs, I found my..last one on the passenger side...wasn't even plugged in, I had been running on five cylinders for quite some time probably..

So..any idea what this could be?

Maybe my wires aren't snapped in on the plug all the way?? Tighten the plugs up some?

Not an exhaust leak is it?

it very well may be..i popped the hood and listened sounds like its on the drivers side..my exhaust hangs pretty low at the H pipe..and since i lowered the car..i've been scraping quite a bit...
