My Grand Prix has a loss of power when it accelerates and does not want to change gears unless I let off the accelerator. When it doesn't change gears, it starts to lag even more and I have heard a knocking sound at times.
My check engine light came on several weeks ago and the mass flow sensor was changed. That fixed the problem I had then, but still have this problem.
It idles good and cruises good.
Was told maybe a fuel filter, but seems more serious than that.
Also have new plugs and wires.
