i'm getting the occasional small backfire when i let off the throttle.

should i just have my car towed to the local scrapheap now?

think new sparkplugs would help?

 

any exhaust leak?

 

not really....maybe a small amount out of the header (cause of my custom two O2 sensor setup,one of the sensors hits the block and gets bent when we torque down the header)

 

No reason to scrap a car over a backfire.

I lived with a backfire for months before a teardown/rebuild. I had a leak in the bottom of my header where the rear brace/bracket is.

I don't know exactly what causes it, because I never fixed mine. I kinda thought it sounded neat...

 

hehe..I was just kidding dude

yeah it doesnt happen a lot,but I wanted to check and see what could be done to fix it or why it does that.
