Obviously its that time of year. When we're all going to work and school in the morning, and its frigid outside and we have to sit in our cold cars. Not sure if it normal, but after I turn the car on, the idle is a little rough, but the exhaust seems like it keeps popping or making a gulping noise. Im assuming this is normal as the car only has 6k miles on it..? Thanks guys.

normal

When it's freezing here in Miami (60F) in the morning, I do hear that, and I sense that as normal also..

Yeah Im so paranoid about the car. I put my intake in about 2 months ago. Ever since then, sometimes at idle, the car will dip down to 500ish RPM and seem like its going to stall, then catch itself..some say this is normal too and some dont. Any ideas? Dont think its my MAF. No CEL or anything either. Happens maybe 2x a day.

You called 60f *freezing* ???????

Damn, I just had couple of 20s of mornings ! What am I ? Hell ? :lol: :lol: :lol:

oh btw to OP, its normal.

Get an aftermarket exhaust, then you really get some cool sounds. My car never popped until I got the exhaust.

my car was doing some weird things this morning. it was -5 degrees F. i started it up, and normally it warms up at about 2.5-3k rpm, but today it went to 4-4.5k, until i let go of the clutch. i thought that was weird. then every thing was stiff, like the clutch, the shifter, and the suspension was like a rock. i hate this cold weather, and so does my 8

normal mine pops and apparently shoots flames once she's warmed up. WOOT WOOT

normal, and its nothing

I shoot 2 feet flames from the exhaust and my car still runs fine

you are also running nitrous

that too

yea its like 15 degress in the moring and i have the same problems

hahah yes i experience this all the time
ATs do it too :)
i drive my car out when it's freezing temp out
and it's crazy if i drive in M, also by letting go of accel. when i shift then step on it right away. WOW *pop pop pop pop pop pop*

put a potato in it.

Do you guys let it fully warm up? Or drive it to warm it up? I let it sit for about 30 seconds before I take off. The rotaries heat up quickly. Alot quicker then my S4 that I miss so much :( Miss that twin turbo =X

I love the popping sound myself

I shoot flames and I've only got intake and exhaust.

you will always shoot flames unless you lean out your AFR

gotta love the popping sound. lol.

knew it was normal... but can anyone explain why it happens?

I think its from the Left over fuel in the pipes, that doesnt get burnt off in the chamber just sitting in the exhaust. i heard mine pop only when i cranked it in the morning but after the exhaust im snap, cracklin, Pop, pop, Poppin on every corner . i love that sound

correct

I never want a car again that doesn't shoot flames.

Glad you asked this question since I was also wondering. Got the greddy sp2 and it burps, pops, car shakes a little. Figured it was okay but good to hear from others on this.

One of my best "8 moment" comes from the exhaust popping... I was driving in a complex set of overpass/underpass at the merging of 2 highways, a bridge and a major local metro/bus station.

Just as I was passing under an overpass, in a curve, after WOTing it, I double clutched, downshifted and at the exact moment I was in the shadow of the overpass the exhaust popped/backfired/whatever. I can only guess that I shot flames, because the white minivan 3 cars length behind me hit the brakes :D

I felt like I was driving a Ferrari or some other ultra exotic lol. Everything was just perfect... engine sound, exhaust, location, an audience... :P
