Not to completely resurrect an old problem, but for future reference it is possible that during installation of new components that the MAF sensor got dirty. Many moons ago I replaced stock air intake on my Mustang and the results were terrible - it was like the car wanted to stall. Took a lint-free cloth and rubbing alcohol to the MAF and was smooth sailing after that.
Just my $0.02.
CC and separator received and installed on Tuesday. Great looking products and easy install. Only issue I had was that the clamps provided for the 1/2" hose were too small... luckily I had some extras in the garage so it didn't slow me down too much.
Did the CRC GDI IVD service and oil change at the same time. I'll check the CC in a few hundred miles and see how she looks.
Thanks again Elite Engineering for great service.
Ordered an Elite Engineering CC and clean-air separator today... plan to install this weekend with my first oil change (got 5100 miles now). We'll see how it goes.
Putting Amsoil Signature Series in FWIW.
