my zafira 2.2 has recently been overhauled after burning out a valve again (did same 18 months ago) ,
this time had a husband of a friend of the wives repair it who is a mechanic , upon stripping engine the timing chain guides were damaged so got a new complete kit for him to fit as well as a replacement head and new valves .so basically engine has had a complete top end overhaul ,
the issue we have now is the car starts and idles fine and revs up fine with no ecu lights or codes but soon as you drive it and put your foot down it coughs and splutters terrible , i have got the car back as he has had the car for 10 weeks now due to various excuses and me not prepared to wait any longer for my car to be fixed , i have checked and cant see any air leaks , car seems to run slightly better with fuel cap removed and fuel return clamped but my question is if the timing chain was out by one tooth would this cause these symptoms ?
