hey guys
Im no mechanic, so I have to use info from friends. I need some solid info, so if you are guessing please don't reply. At high revs in first gear when changing to second , I get a pop from exhaust, its not loud and not everytime, + i don't loose power. My mechanic friend said don't worry. unless it backfires.. something to do with the efficiency of the ignition system, that at high revs sometimes it will miss.
ok do I need to get it tuned "only done 5000ks ago, or check the coil packs" don't really wana have to keep retaping them" or ignore.
thanks
