obd0 swapped b16 89si hatch, starting to have a slight miss all the time really noticable at lower rpm's (1500-3000) i can beel it and hear it slightly, and every once in awhile while taking off it will sputter like its low on fuel... that doesnt happen often though... thinking maybe my tps? and i put reman axles in it and they lasted less than 2k miles, started grinding/clunking so i replaced them with brand new (not remans) and ever sence then its still made the same vibrating noise as with the other axles, it only happens when i let off the throttle and it did this before with the other axles from the start also....
so i have brand new axles 90 teg, good int shaft 90 teg, brand new upper lower ball joints and upper controll arms, anso new tie rod ends.
all that and i still have a vibration described above. oh and the miss at low rpm's..

 

anyone got any ideas whats going on?
