hey guys, i was driving down the highway and all of a sudden when i went to pull a hill the car started missing and shaking. its missing bad on multiple cylinders. but yet doesnt throw a SES code! it does it when its both in open loop and closed loop. it is running really rich and is missing, i just cant tell if its missing because its so rich or if the missing part is causing tons of unburn fuel to be passed through the engine. i cant drive the car because it does it idling and all other speeds. it happened instantly so it makes me think something just failed but i cant figure out what! ive tried the coil wire, coil, map, and maf. still no solving the problem! please someone help me with some ideas.
thanks in advance ive got to get this fixed as its my daily driver
