Hi all

tried to post this at the weekend but it went astray...


my son has a 2010 2.2 diesel Mazda 6

he had the cam chain replaced recently at a local garage (not main dealer).

ever since it’s been under powered. Struggles to hold 70 on cruise in the motorway.

He took it back there but they say there’s nowt wrong.

my guess was they got the chain a tooth out but would it run at all like that ? It revs fine when stationary. Just has no grunt in the road.

suggestions please.....

TIA
