Lately my b16a turbo has been doing a lot of backfiring/ a little misfire at light throttle, just cruising. But when I put some throttle so it it goes just fine.. I was thinking it was the spark plug wires, or fuel filter or a combo of both.. But talked to my tuner and he said it was the map sensor, as it is still stock.. Any input? Edit: forgot to ad the car is on e85.
B16 Turbo backfire/misfire light throttle..

a 3 bar map sensor will do you good for now and for the future, but do change out the plugs with some proper plugs firstI'm agreeing with everyone else on MAP sensor. Also, I was getting slight backfiring because I started running a bit lean. Ensure your fuel maps are good.
Yeah my tuner has all the timing and such set for the e85. Plugs are NGK racing, gapped at .28 I think.. But I haven't changed the wires. Anyone have a diagram on where the map sensor is on a hatch? I looked in the spot behind the intake mani and didn't see it.
i would like to know this also, my boosted d16y5 backfires alot since i got it tuned after the turbo install. it was quite loud with open downpipe and i could feel it under my seat but with full exhaust now i usually dont hear it, it seems to happen when i give it medium throttle and shift to slowly. i also have a stock map sensor but i figured it was in the tune as im tuned pretty conservatively since my block is stock.
