hi everyone, I’m new, I have a rest 2007 3.6v8 and it keeps going in to limp mode when hard acceleration, loss of power and change in exhaust nots. Had 2 new egr valves, still happening, turn off and on all ok, the mechanic who changed the valves says he can’t find the problem. Have taken it to a different mechanic and he says it’s a worn turbo, slight whistle and that both turbos need changing, which means body off. Waiting for quote but anyone have any thoughts? Could it be anything else? Thanks in advance!
