Help please! Phase 2 V6 GTV - no power
Just got back from holiday to a flat battery. Nut on the negative battery terminal connector rounded so had to cut it off and fit a new one.. Charged the battery and hooked it all back up. Car starts and will just about drive but there is absolutely no throttle response at all - the revs won't go above idle even with the pedal to the floor. No warning lights are on.
Car was having very intermittent flat spots at 4000 rpm every 3 to 6 months so think the MAF was on the way out but was fine before the battery went flat.
I've tried disconnecting the MAF but it makes no difference, other than the warning light comes on. No throttle response at all.
Started to unbolt the MAF sensor but one of the bolts has sheered off - it has been one of those weekends..
There is also a rather large split in the hose from the airbox, after the MAF which has been taped up, courtesy of Firela in Clapham when they did the clutch a few years ago.
Before I order a new MAF (GM equilvalent) and hose section, does this sound like a MAF problem or something else? The battery (Bosch) has not been changed since I bought the car in 2007, could it be this or something else? All was fine before holiday! Any ideas? Thanks.
