ok, so my car has this weird idle that it started randomly about 2 weeks ago... i cant figure it out. it "braps" almost like a bridgey, but it didnt do this until a couple weeks ago. the car runs wonderfully, just idles weird. ive sprayed and sprayed brake cleaner and cant find any vacuum leaks that way. ive checked timing, its good. possible carb issue? i tried tuning the carb, but it didnt really help at all... id like to get it all sorted out before dgrr lol
