OK Ive done a 328i conversion with m50 manifold as some of you might know.
now the car runs, starts first time every time,but cuts out after 30 seconds or around abouts.will stay running if you leave foot on the gas.now the engine was sitting for a year or so. now i'm looking at getting the engine tuned to the best it can be! but i do not know where to start or whats needed to accomplish this?. im learning as i go along, so some steps to follow would be good. thanks in advance. i will carry on reading reading reading on this.
