I have notice that the gauge of oil pressure on my LT1(m6) is acting weird, when the car is hot, the oil gauge isn't consistant, like it moves a bit up an down at idle, at the same time I hear the flowmaster muffler pop a bit( don't know if the sound like that) the same ting happens when I am at a traffic jam, an I give just a bit of gas 25% or less on the pedal the oil pressure rises but, the gauge goes just a tad up and down.. and the car doesn't revs as smooth as my a4 lt1

I am hearing a sound like a exhaust leak..or plugs cable burn...

can it be an exhaust leak

the plugs an wires are new ac delco, (maybe one of them got burn by a manifold?
