can you take a vid? if so pop the hood and get to taking that. if not can you explain it a bit more. where is the rattling coming from...try getting low on the motor and tracing hte smell...if it's something burnt it should be easy to find
The idle just sounds just as rattly as accel. Constast, click click click click loud. Its already night and I have no light so ima put one up on morning, but when I reved loud smoke came from underhood.
