Backfiring......

[LAXbronco65]

My car backfires at every 1-2 and 2-3 shift when i take it to redline. is this bad and what could be causing it. it doesnt bug me too much because it scares people. one of my friends said that flames come out of my tail pipes too. is this bad for anything? I think its kinda cool but i hope its not hurting my car.

Did you advance your timming at all? Flames out the back!? Thats pretty crazy considering you have a catted midpipe. You ever check your A/F? The only thing I can think of to cause that is some SERIOUS richness up top.

I had a bbk x-pipe that did that as well....could mean your running really rich OR lean....when i got dyno tuned after blower install my tuner was able to tune it out..the x-pipes do that anyway to a certain extent...but it should be looked in to,that shouldnt be happening that bad...just my 2 cents.

Agreed, Mine does it too, but it's pig rich!

They're right its running rich. You should have the ecu scanned, my guess would be an O2 sensor, but who knows.

im pretty sure that at least 1 of my O2 sensors is bad. im gonna get it dynoed in about a month so ill have them run the A/F when i get that done. so its not hurting anything?

You're pig rich, my car does the same thing and when i got it dynoed a week ago it was at 10.7:1. Get a tune, thats what im doing. How does the car smell? it could be a bad O2 but i bet its cause ofg richness.

 

[LAXbronco65]

its not doing it anymore. i have no idea why but it stopped. O well, im not gonna worry about it.
