Hey Guys,
When lightly accelerating I notice what almost seems like what I would consider a noise similar to a cat heat shield rattling, or stones rumbling. This is only at 1200rpm 1500 rpm and only on slow acceleration. (that I can tell). it comes and goes by 1600 but its annoying, and can hear outside of the car as well.
Only in when driving tried to see in idle
Any ideas other than just accelerating harder all the time?
I read that bad gas can cause something like this I actually used a different gas from brand new station, Before Shell V Power
