Could this cause any problems? engine was running a bit rough(idling funny) at one point. then when i turned the car off had lots of trouble turning it back over.
This will happen not very often, maybe usually once every couple of months but seems to happen if im giving it a bit (eg going up hills) and then when i come to idle at the lights or something itll run really rough.
Ill give it a little touch of the accelerator and it will idle up high then go back to a rough idle.
