hi not sure if any one can help...bought a mk6 which the owner said had 2.0 zetec conversion, it still had 1.6 tb so changed this for a 2.0 tb all ok...then managed to get 2.0 maf car did not like that one bit...checked ecu and still fitted with 1.6 ecu...got hold of non pats 2.0 mondeo ecu and wired it in fitted 2.0 maf started first time a bit lumpy but i thought it needs to reset it self...once it had found its base idle i drove it would not rev past 4000 in any gear unless it was on 1/2 throttle any more than that forget it...low rev range almost to lumpy to drive...engine no are not on crank case so any othe way to find out if it is a 2.0 without removing head or maybe some other fault thanks
