Hi Ya,
2003 Vectra Elite 2.2
Car seems to have a SLIGHT feeling of like a flat spot between 1100rpm and 2000rpm. It idles ok.
Just when you drive it, you know its wants to go and it holds back, almost like a slight jerking effect.
So far:-
New coil Pack
New plugs
Cleaned Throttle body (was very clean to start with)
Plugged on to diagnostics (and also while in motion) No errors showing
Now,
If the coolant temp sensor failes and or the lambda probe failes, or are out of range, would this show on the diagnostics?
If they do, then i'm out of ideas......
The car idles and drives ok! (apart from the flat spot at the lower end of the revv range)
