drivin car today,everything cool then came to light and car was idling fine then i heard a small pop in the exhaust. pulled over and heard it again very random and not "back fire loud" but still there (fire cracker loud)look as sig for mods . broken exhaust valve spring, weak plug.
i didnt chance it and had it towed, p/v interference w/broken spring???

your help will be greatly appreciated

 

anyone out there!!

 

If its a little pop it might be normal, I started hearing a little pop from time to time in my Z once I started modding the exhaust. You'll have to look if you think you broke something, take off the valve covers to look for broken springs/rockers, do a leakdown to check for messed up valves.

 

not normal as it doesnt follow the lope. poppin in exhaust is un burnt fuel igniting so i guess ill look at springs- not push rod issue?

 

anyone else

 

Is it an A4? I hear poping sounds when ever I gain some speed, let off the gas, then barely press down. It started to happen when I installed my exhaust.

 

yeah

 

anyone else!

 

hehe, well personally I think it sounds bad a$$, but that could just be me
