I have a sprk problem, it seems to miss fire when idling and when driving in low rpm. It also doesnt want to start when engine is hot. I changed spark plugs and wires and the coil pack. what should I change next. If anybody can help that would be great. Thanks.

 

It is always helpful if you provide info like;
model, engine size, anti-theft etc. It may also be misfiring at a higher RPM , but just not as noticeable.
