So I’m having issues where my plugs foul after about 30 miles of driving, and cause the car to break up in the low to mid rpm range and getting less than stellar mpg. I believe I’m running too rich because of the major carbon build up on the plugs. Its a fresh rebuilt y8 with with less than 1500 miles. It has skunk2 intake and tb, comp cams QuickTyme 105100 stage 1 camshaft, 4-2-1 headers with cat delete, stock mid section with a axel back muffler. Everything else is stock. Now I’m untuned for now (saving up for a s300 and tune session, they ain’t cheap lol). But my major question is, will putting a 1 step hotter plug keep me from fouling plugs until I can get it tuned? And if so what recommendations would anyone have? Any help will be greatly appreciated and thanks in advance!
