Cold Start - Thumping Sound?
Now that the weather is getting colder I've been noticing a thumping/thudding sound coming from the exhaust during cold starts. Not sure if this is something I should get checked out (no CEL etc.)...it's just a sound I never noticed during the summer. I found a youtube video that exhibits the same symptoms:
Sounds very similar to 0:11-0:15 and 0:30-0:32 except mine "thuds" a bit more. Is this normal? Anyone else hear this during their cold starts? |

Yeah I get that little burble too on start ups. I'm pretty sure that's just the way the car is tuned and there is a little bit of extra fuel that is injected during those situations.
