[QUOTE="rubior, post: 16891941, member: 204618"] Hey guys i was wondering if i could get some opinions on my issue, when you give it 3/4 throttle or full throttle it starts bucking, hesitating & backfires, & if your idling & step on it it literally cuts at 3000 ish rpms, hesitates & backfires & the rpms slowly go down, i replaced the spark plugs with ngk iridiums & plugs with new motorcraft plugs, i cleaned the air filter, throttle body, changed the frps & nothing, theres been 2 times where it backfires & the car turns off, & once you pick up speed easing into it, if im able to get it at 3/4 throttle it has literally no power, other than that the car runs & drives good, only misfires super randomly, sounds kind of bubbly, & it smells really rich, i dont know what to do or how to diagnose it, ive googled & honestly nothings been helping, [/QUOTE]
