Title: Looks like 4th of July!
Post by: CDog86 on October 20, 2014, 12:07:47 pm

Hey guys, so I went out this morning to start my '86 scottsdale and for some reason it was flashing out the exhuast. So what I was thinking is the fuel mixture is too lean so it is combusting as it comes out the tail pipe as it gets hotter? Anyone else had this problem or know how to fix it?

Thank you

Flashing, as in fire coming out the exhaust?  Did it just start doing this today?

I would say "fire" but yea it's like little "sparks" and yes today was the first time I have seen it do this?

Case closed: to lean of an A/F mixture and burning off all the build up in the exhuast pipe
