Best Answer

The most common cause of rough idling would be a bad or clogged fuel injector. Also look for the hose on your EGR valve. They tend to come off in hot weather. If the hose comes off the engine will definitely run rough. I had to put a small hose clamp on mine to keep it from comming off.

Its idling rough because you probably have a blown head-gasket and lost compression at two cylinders you need to remove all spark plugs and check each cylinders compression.
