ok so i got my new ecu fixed the alternator wires that broke up and drove my car. it drived amazing for 1 day, the second day it was driving good but then all of a sudden it started to back fire but the boost would fight through it. then the following day the backfiring got a lil worse..but still fighting throught the RPM's, then soon after here we go again, she starts to sputter as soon as i hit full boost! wtf is the problem now? why would she drive great for 1 day and then all of a sudden it would start to sputter like before
.
i've noticed that when i hit full boost my battery voltage would go from 13.9-12.7ish, its this normal? i didnt look at the battery voltage when my car was driving good for that one day so i dont knw what normal is. also i checked my plugs they werent fouled out. and just to rule out the coil packs im gonna switch with my boys 2j, but i knw thats not the problem. cause then my car would of been sputtering all along and not drive good for just that one day. im also gonna switch ignitors, but im pretty sure thats not the problem either.
HELP!
