Re:turbo/engine back fires

Re:turbo/engine back fires
 

ahh dont worry as long as you dont backfire from your intake manifold is cool

Re:turbo/engine back fires
 

yeah im getting used to it kinda cool, i use to scare kids and old people ;D

My friend did that, and he upgraded his ignition and it stopped?? maybe try some colder plugs if you havent and get a stronger coil or something? Just some ideals

unless your timing belt skipped a tooth for whatever reason; otherwise it's normal if you know youre rich.

I had it all the time... ;D
at night on the highway spitting out flames was nice.
I was running pretty rich to...

As much as this has it's novelty value, please look into it. Usually timing (like skipping a tooth) plays the part in it.. well from my SOHC experience.

Running rich can have a number of features, but you have to be running uber rich to get constant back feed like that. Look into ignition issues a bit closer, your problem may be simple (well simpler then tuning out that rich run at least).

You run rich, there's unburnt fuel in your exhaust gases, it gets hot in your exhaust pipes and boom/voom. It could be other things, but usually the car is just running rich.

My WRX does that all the time, of course they run way rich from factory, but it's fun to scare old people.
