poundy i need a new one on the main part of the exhaust as the wires have broken. the mass air sensor needs replacing i recon as it is very spluttery when its cold any idea of the cost for these???
MikeS mass air flow meter - ebay lambdas cost around £60 your symptoms sound more like damp coil pack or coolant temp sensor
vocky make sure you have the egr blanked, then replace the coolant temp sensor also worth checking/ replace the plugs (don't over tighten them)
