Ok I'm experienceing a funny problem an I need all the pro help from SM. I have read as much as I can find on SM about plugs and gap etc.
My problem is a misfire/sputter which only happens after driving the car for 20 or so minutes. It happens through all rpms and at idle. It does however stop when coasting in gear.
My current setup is 12 degrees BTDC and running NGK platnium plugs. stock gap with 12-13 psi. What is your opinions guys?

I also forget to mention I recently swapped from turbo to n/a cams. I replaced the valve cover gasket thinking oild was leaking out. But it was not. It is clean in my valley.

The problem is fixed.. :) It ended up not being plugs at all..... I did however change them out anyways. My number 2 cylinder injector clip wasn't attached all the way.... Silly me missed that, since I haven't touch my injectors at anytime while I owned the car. Probably A silly look over from previous owner who used to have 550cc injectors.
