Please help me figure out whats wrong with my 03 g35 with 120k on swapped engine.
Recently replaced spark plugs, coil packs, valve cover gasket, and oil pan gasket.
Idles around 1k rpms sometimes lower sometimes higher but only as high as 1200 rpms after replacing coil packs and new plugs it still misfired. After turning the car off and taking out the Maf sensor and putting it back in the cel turned off but its still misfiring. Also sprayed for vaccum leaks what else should i look for?
