99 - 02 Cordoba. Car started to jerk and stutter, engine light flashed for a while and then remained solid. Car struggles for power in the first 2 gears. My previous experience suggests that it's a coil pack, ignition lead or if I'm unlucky, a failed cylinder Is there some way I can find out which it is? Even if I could find out which it might be between ignition lead and coil pack? I don't want to have to buy things just to eliminate them from the potential problem? I checked the ignition leads, and one of them(the lowest one) seemed a little loose at connection point to the coil pack. I pushed it in tighter, but it made no difference to the car, which repeats the above symptoms every time it is started. Obviously a VAG tester might narrow it down, but I still doubt it could tell me whether it's coil pack or ignition leads since the error code would probably be the same? Anyone any tricks or tips as to how I can find out for sure?
