what engine would be useful info also what you have tried so far and have you had it on diagbox to check for faults or look at live dataWell today she has chugging along under hard acceleration. Ive found air in the fuel system, beld it out but seems to be getting more in but dont know where from. Have just bought a egr block off plate so will fit that tomorrow.will it need a remap?
if you read the posts someone has suggested to check the fuel lines under the airbox this is a common problem but it looks like you are ignoring them, also was it dealer level diagnostics used if not then i would recommend using dealer level as there might be some codes the reader has missed also you need to have a look at live dataWell had her to the garage. No major falut codes and blanked the egr off. Car was running fine again then today she cut out today. She is only doing it when cold. The garage said there was a fault code for the glow plugs which i will get new but i dont think this is the problem. Once warm she runs sweet.any ideas?
