My car just recently started to make a popping noise when I am in neutral or jsut have the clutch in and rev to like 6k. It doesn't do it till I let off the gas and the rpm's start to drop. On it's way down it makes a popping noise almost like a small backfire but not as bad as a real backfire. So is my car running rich or lean or what? Thanks

Do you still have your acv and airpump? If not it could be that the lack of the anti afterburn valve inside the acv is causing your problem. Dumps fresh air into the intake upon rapid deceleration to prevent your symptoms.

 

mine dose that to i cant figure out y

 

same here, both my engines and my friends 1st gen

 

I actually just removed my airpump. So would that hurt my car or not???

 

What would I need to do to shoot flames? Gut the cats? Would this new problem help me to shoot flames? Does this mean its not getting anough air/fuel or not enough?

 

I'm shooting flames like a mother, f#$@er, that's what I've been told. Pretty simple set up. I wasn't trying to get them either....nice bonus I guess

 

sorry, here's the setup
