Hi Guys sorry I know I only rock up every 3 years or so when I have a problem, but could do with some help. I did the whole throttle body upgrade thing which i dont think is at all related but its possible. Used car after that OK....its been stood a while, but now starts but almost seems like low petrol, Ive put in 25 litres... I could post a clip...but start...frudump, frudump.. like more cylinders join and will run on 7 or so at about 2500...occasionally seems like the number 8 chirps in and joins the party. Sometimes will run as long as i fettle the throttle .... other times just sort of slows and stops. Any ideas from the wealth of knowledge out there?? Any help much appreciated. I’m kinda thinking fuel pressure maybe... on the fuel rail valves what sort of pressure should these be at...should it be fuel everywhere spray or just a short spurt with ignition off?
