2002 Renault Laguna 2.2dci issue

Hey all,

My 1st post so please be gentle lol
Ive got a laguna 2.2dci, when accelerating it brings up the coil and injection light, ive changed the intercooler as it had rotted, there wasnt a noticeable amount of oil in it, when idle the car will not rev past 4000 rpm, the diag scans have 4 faults all pointing towards the air flow meter, would a faulty meter cause the car not to rev properly?? Ive also cleaned the egr valve, it was dirty but not overly clogged

Any suggestions are welcome...
