Well...my car is not registered or insured because i won't be driving it till it's completely done...which isn't anytime soon....so I decided to turn on the car today and I left it on for a while. Then...I revved the engine to about 4k and let go of the gas, it backfired. Aslo...when i turn the car off...right after the engine completely stops running, it backfires. Like 'POP!" and I want to know if backfire is a bad sign?

Thanks

 

No it's cool man thats what RX-7's are famous for. We here love backfiring.

 

hell yea backfire's r the **** ....but that's wierd that it pop's after it's already shutoff, after how long of it being shut off does it pop?

 

don't worry the pops after shut down is normal as well. It just tells me you have a header and pretty much free flowing exhaust. It's one loud pop like 5 seconds or so after shut down right?

EDIT just read your other post, nm on the headers haha. prolly just a leak somewhere.

 

my car pops like a **** anytime u let of the gas no matter what rpm..and i guy the sc rx7 club part his 85 back fires while ur driving anytime it feels LOUD AS CRAP!!!! and after u turn it off like at the meet he pulled up parked closed door we all go 3-2-1 BAAAMMMM

 

mine has never poped after its been tured off is this becuase i have no after market header?? right now i have a racing beat cat pipe,,,to a racing beat muffler (alittle to quite for my taste,,,im gunna get the stock over axle pipe and weld a n1 can on it so i can be kool like all the ricers!!hahaha )

 

phew...I guess it's a cool thing then :-D Time to start backfiring at everyone lol. OWNED!

 

To throw more ice on your party...your ok, my lil bug backfires decelerating and I got my first pop after 3 seconds or so of having the car turned off. I just laughed my azz off and said,hmmmmmm ran great, cant complain! I wish our racetrack was open....I wanna take her down the track, even tho Im kinda scared of the car when letting off the gas passed like 60-70 mph...lol...dunno why my bug swayes so much.

67 bug with a 12a
RB intake/465 Holley
Two 2" pipes(maybe 3ft)into a Y collector into a muffler(soon to be Borla)

 

does this mean if you pull off the deceleration/backfiring solenoids and associated parts in the rats nest there will not be any adverse effects? will this affect emissions? i need to be able pass ohio emissions testing, but would like to simplify things as this is going to be a csp autocross car.

 

caught mine on camera the other night to show off

 

lol! Sweet...

 

mine doesn't backfire

 

wtf? Those pictures are so blurry. Do you have exhuast on the car

 

Mine used to backfire until the engine was warm, and sometimes it would backfire when I turned it off. Then I put on the Racing Beat header and the backfires went away. I haven't heard one since. Strangely this is contrary to what most people say. Maybe messed something up in the carb when I installed the header. Could I have done something to lean out the mixture?
