MY car has a new nasty rattle at around 2200 rpm's, sounds like its coming from the glove box area, i have a feeling its coming from the engine department though... any ideas? i just had new spark plugs put in, & underdrive pulley, doubt it could be the pulley but yeah.


on another note my car also starts roughly and feels like my engine is vibrating more at lower rpms, could it be a poorly installed plug?

if anyone has any idea, please post!

Thanks guys

These cars tend to rattle and make strange sounds after a while, at least in my experience. Under drive pulleys could certainly make it vibrate more. So could a vacuum leak. I'd check my vacuum lines especially if it is starting roughly.

Also, if you have a CAI, make its clamped down good and you don't have any leaks after the MAF.

What underdrive pulleys do you have? are they piggybacks? I have read on many forums and reviews that sometimes the piggybacks can cause excessive vibrations. Like I said "READ". Doesnt make it necessarily true though....lol

I too have heard that piggybacks are crap. : /
