[redmx3]

hi, i own an mx3 but just swapped a klze from a 6 in there
two problems really
first it was smoking really heavy and then started to missfire
further inspection revealed that the plugs had been chaged from the 1.8 into the 2.5
after a change of plugs and a oil filter and flush, the miss had gone the the smoke still remains
there is no lamba sensors and i was advised to check for oil in the IM, and there was,
so im stuck, any help would be so greatly apreciated
kindest regards
chris
