I'm not throwing codes or CEL but I have the rough idle and cold start. I already replaced the VVT motor but I installed it wrong and I think fried the new part. I'm saving for it again but this time taking it to my indie mechanic because it took me 9 hrs the first time and messed it up. Lesson learned but it's ok to drive with the VVT not working (the vanos and such still works as intended but you lose the fuel eco and a slight delay in reaction time when throttle is pushed). But do replace the items needed before modding.
Might want to do a valve cover gasket and VVT gasket. There could be other parts that need replacing but those are the basics.
