Well I just got done putting on my exhaust, and now after it was warmed up, it would randomly bacckfire through the carb, 1000-3000rpms. I have a holley carb and edelbrock performer intake. The car hasnt been ran in like a month or so. could it just be from sitting?

hey, i had that problem to, do a search and see what pops up, it means that it is usually to rich...., i think. do a search, you should beable to find out for sure. could be a switched up spark plug wire to.

I did a search, and it seems like it could be different for each person depending on their components. I know its not a switched spark plug wire.

Just backfires out of the blue at cruise speed without moving the throttle?

My car isnt on the road I warmed it up to change the oil. I was reving it up and sometimes it backfired and sometimes it didn't. It happened at any rpms between 1000-3000.

no consistancy to it?

maybe the timing's off?? powervalve??

Is it backfiring when you hit it or after it starts revving?

It does it both times it could be when i just start to rev it our while its about 2000-3000 rpm off idle.

Check your timing and advance. It might be a little bit advanced.

sounds like u should...buy a new car..lol j/k idk, ill stop by at take a look

Hey 79blue I doubt you could fix it. But if my timing hasnt changed since I first ran it why would it cause this to start.

if there is any consistancy it could be a valve problem, your sure it isn't carb?

I think its the carb or maybe even the choke and is there any ways to fix it?
