i have a civ with a gsr swap, ran 100% till last week, it was acting like it had water in the gas. sputtering and skipping at low rpms. then the vtec stopped. i checked my oil it was low! when i added some it came back. now its at the right level and vtec stopped again and it idles around 1500 rpm, its running like its cold!!!! wtf is wrong?
