She felt like my old NA and the idle felt more crude after I changed the spark plugs, cleaned the throttle body and the MAF sensor....but then I gave her a battery reset after the test drive because she had to learn that the throttle body is no longer filled with filth. She's now smoother than ever and while it goes fast, I lost the NA crudeness I crave for. I t almost felt and sounded like I had an cold air intake. I'm sad.
