My plastic top 2.0 Cloverleaf has a fault and I'm not sure where to start.
Basically it's hunting like crazy. And horrible to drive.
Start the engine (it starts fine). The rev hunts between normal and 3.5k - so a lot. If you slowly press the accelerator downwards, it makes no difference till you get past where 3.5k would be.
If I unplug the MAF, idle returns to normal for about 30 seconds but then gradually increases back to the 3.5k hunting.
Under driving, the engine will slowly surge on and off below 3.5k and is difficult to drive. Above 3.5k seems to drive fairly normally, although a little flat... Seems strange that an idle problem effects the drive of the car when you are moving.
Any ideas guys? I'm just off out to drive car with MAF unplugged.
