sputtering, backfirign in downpipe?
Hey guys, i have a b16-T with a 2.5 turbo back, tuned on hondata, @ 8.5psi
Lately when im driving the car seems fine unless i accelerate past 5k.. at WOT, the car will run fine up to around 5k which is usually around 7psi at that time and the car bogs and it sounds like the car is backfiring but the noise seems to be coming from in the engine bay. IT also isnt one loud noise.. but several sequential noises almost like loud sputtering.. other than that the car's overall driveability is fine. i tried to ease the motor above 5k rpm and i did then i opened the throttle up and it happened again only this time at around 6.5k rpm.
I occasionally get a primary o2 code but ive been running without o2 sensors for some time now with no problems. With the o2 code I also sometimes get a tps code.. this i usually just clear while moving by killing the ignition then popping the clutch.. could the tps be the source of this problem?? thanks

sounds like possible fuel starvation. Do you have a wideband? What is your fuel pressure? Injector size?

sounds like the same crap that is happening to mine, but i'm NA. it doesn't happen all the time just occasionally. I go up to about 3K and it starts sputting rmps drop to about 2.7K them the car takes off back up to 3K and falls back down to 2.7K and repeats depending on how fast i'm going and the rpm range i'm in.
but it doesn't do it all the time just occasionall. so i'm confused as hell
