Nice! Yeah I like Yimi. I wish they were closer to me and I'd be there getting only their help to solve this. I'm in Simi Valley--Ventura County.
Regarding the spark plug issue...that's what happened. They previous owner put the wrong ones in. The plug on 4 was all black and nasty. Fouled nice and good. I've got the correct .28 NGK in there now for all of 'em.
What the heck could that whine be? Almost thinking I should make a vid and let some people on here listen to it. It's NO GOOD Well, that and the smoke...
I have an FMIC, so I'm still working out the full recirc setup. This car also had a CAI on it. I would rather have the stock intake but I'm trying to make it work with what's on there to save some money.
