Back fire?

do you get a jult before it happens could be fuel cut?

what is the spec on your car? it could only be popping flames if you are running rather rich

Same thing is happening to me and i think for sure im running rich i can smell the gas in the fumes.

its a 1996 with bailys dump valve hks exhaust and indution kit running pretty stock

then it shouldn't really pop flames, the only reason i know of it fuel cut that's when the car goes over it's stock boost level around 0.85

and for safety reasons fuel cuts happens, this will result in a big jerk then sometimes a backfire or flames as there is unburnt fuel in the exhaust.

if you don't already get a boost gauge, then see what you are boosting at before it happens and report back.

thats sounds right im gonna invest in a boast controller and in the mean time will just drive softer cheers mate

try reeving it up not in gear to near the top then half throttle it as it comes down the rev see what it dus,

myn ust to do to that and it was one of the wires going in to the ICV simple fix
