I have a 2011 1.4 turbo. When I come to a stop, it's been vibrating and feeling like the RPMs are flucuating. I look at the dash and it dips slightly. So I has a short ram CAI in it. I tightened everything up and I'm going to replace the plugs. I took them out already and saw that one or two had a good amount of white powder on them. Too hot? I'm getting AC DELCOs for them and I hear they need to be gapped to .30 from .29 to correct the issue? I also run 93 octane. Any advice would be appreciated.
I'm having idle issues with my 2012 Cruze LT RS. Codes came up for intake and exhaust. I am using a drop in K&N not a CAI. I did remove the intake duct from the intake and found oil blow back from a faulty pcv, which is molded into the valve cover.
