Rough idle in the K-Jets are usually caused by air leaks. Cracked or swollen hoses, bad gaskets, and worn injector seals all let unmetered air sneek by the air flow plate giving you a lean mixture that cause a rough idle. Other contributors to a rough idle would be the Control Pressure Regulator (cold or warm engine) the Auxiliary Air Valve (cold engine) or worn injectors (warm engine). Below is a diagram of the K-Jet System layout in your vehicle. If you check each system for leaks & function I'm sure you will be able to smooth out that rough idle. Good Luck!
