could be that the IDLE (u spelled it incorrectly but just a beginners mistake) is set to low u can adjust it by turning up the idle adjusting screw, its probably not a vacume leak unless the rpms are bouncing (going up and down) timing should be fine unless u played with it, if uve got new plugs and plug wires they should be fine right? might be injectors, u might want to run some injector cleaner, and with the car running and someone steppin on the gas a little around 2k rpms spray some water directly into the intake with like an old windex bottle or something, the finer the mist the better, just a few sprays every 10 seconds, this will help if there are any carbon deposits, check the butterfly valve on ur intake manifold for signs of crud, if its relatively clean ur throttle body probably is ok and doesnt need cleaned but there are over the counter cleaners available at any parts store (autozone), with regular maintanance the car shouldnt have idle issues unless the idle screw just needs adjusted, make sure u do ur normal (spark plug/plug wires/cap and rotor/oil changes/etc. ) maintanance to maintain ur car in good working order. best way to clean ur injectors is to pull them off the fuel rail (or more of an accurate statement pull the fuel rail off them) and remove them and let them soak in a cleaner made to clean them. there is a cleaner called GUNK which works well for cleaning the fuel system as well as STP. good luck
