Engine backfiring?
Posted: Wed Mar 07, 2012 5:56 pm
ok ive done the following mods and just stated the 95' z26 and it seems to be backfiring alot,
I realize there is VERY LITTLE back pressure, ive done an obd2 swap but havent tuned yet,
is it just because it needs a tune?
I let it idle for about 5mins and shut it off because the backfiring seemed to get worse, should i let it idle longer?
