I just got my HKS Hi power for my 04 AT and there seems to be a rattling noise whenever i'm stopped in Drive. Anybody else experience this. Also, if it matters, i'm running a kenstyle rear with that as well. In neutral it seems to be fine, but the problem is when i'm stopped in drive.

Any suggestions mucho appreciated! thanks.

 

stopped in drive, and neutral should be the exact same thing....both idle - maybe theres a problem near the tranny area? only way to know would be to put it on a lift and check.

take it back to the shop that installed it, and make sure that near the end, they attached the ground wire on the muffler can

 

kay.. will do.. thanks

haha i just realized you run the same kit setup as me.. is your authentic or replica?

 

got it fixed.. just a loose bolt
