I HAVE AN S13 SR20DET BLACKTOP SWAPPED INTO MY 72 DATSUN 510. AS FAR AS MODS GO ALL I HAVE IS A TURBO MANIFOLD, TURBO BACK EXHAUST, FMIC AND INTAKE AND THATS IT. STOCK EVERYTHING ELSE. WELL THE OTHER DAY I DROVE MY CAR IN THE RAIN AND SUDDENLY MY CAR STARTED MISFIRING. TURNS OUT THE NUMBER ONE CYLINDER TOWARDS THE FRONT OF THE CAR IS NOT GETTING ENOUGH OF A SPARK OR NONE AT ALL. IVE REPLACED THE COIL PACKS ALONG WITH THE PLUGS AND STILL NOTHING. ANYBODY HAVE ANY INSIGHT ON THIS
