Plugs were pulled and layed out in the order of which they were pulled. Front of the engine (left) through to the rear (right). Photo #2 shows cyls 1 and 2 Photo #3 shows cyls 3 and 4 Is this normal? What's going on exactly? I've not seen plugs fouled up like this before plus, the buildup on cyl3's plug (shown in the last photo) is substantially more noticeable than the others. #mazda #miata #NA #bpengine #sparkplugs #sparkplug #oil #combustion #fire #engine #checkengine #cel #mx5 #gatewaymiataclub #oilconsumption #coolant #antifreeze #ignition #coilonplug #coilonplugs #coilonplugconversion (at Stone Meadows Subdivision)
