Ok im in need of help here guys, I have a standard agu apart from a remap with 100000 miles on it. Its recently started to smoke when starting up/warming up and if i let it sit at idle for a short while the blip the throttle it spits out a huge puff of black/greyish smoke. Any advise would be exellent. Also the car runs fine nothing wrong with the way it drive and pulls through the revs at all.
