I recently changed the motor on the g20 I deleted the egr and for some reason I feel a lagg on acceleration...I thought it might be a vacumm hose and I can't seem to find it or what can I do if its not a hose .. another question is how can I get my speedometer back. Em I suppose to buy another wire for the 92 p10 speed cable or is there some thing I can do to fix it thanks. I have a 1992 g20 5speed pictures would help
