Car runs fine when cold and warm, once it gets to hot, on faster acceleration and super slow driving (like parking) and at red light in gear (automatic) the engine starts roughing about. Sometimes it even stalls.
Cleaned spark-plugs and distributor, changed fuel filter, air filter and problem continues.
