Hey scotty! Is me again, I have my 2009 Kia spectra and thanks for helping me back then with the engine codes LEARNING so much from you I APPRECIATE IT!! :)
What I'm experiencing on my car is the following. I start up my car, after its warmed up either stationary or moving, it now make a small rattling noise.
I live in Northern NJ, the weather hasn't got really cold yet its nice and decent in the 60s and sometimes 70s, ANYWAY
What can be my problem?

Thank You

often worn catalytic converters do that inside, check that under the car first.
