I did the cam covers earlier in the year but i did not use the o.e.m ones so you gussed it they went so last week got one side for vaxuhall and put it on the drivers side as that was the worst leak....checked to see if the passenger side was leaking and you gussed it it was. So i cleaned all the plugs and leads and rebuilt it (so i could go order the other side gasket) when i finished and started the car it ran like a bag of crap sounds like only running on 5 cylinders not 6 but no fault codes i stripped off the plenum again check the leads and rebulit no change....So i got the other side and did that yesterday and checked everthing over and rebulit double checking as i went started the car and still no change. So i left it and went out to it again today striiped it and fitted new plugs rebuilt and got no change but got a fault code 93 hall sensor voltage high (what ever the hell that means
?).
So i stripped it down again fitted new leads only because i had them anyway and was going to fit them at some point.....rebuilt it and started now i have got fault codes 93...73 (Mass Air Flow Sensor Voltage Low) and 57 (Idle Air Control Voltage Low).
Now i'm stuck not sure were to look or what to look at.
Please anybody any idea's.
