idle stuff

buy a haynes or bentley repair manual (20-40 bucks) and get out your voltometer and check the ohm's and voltage resistance in these things throttle position switch ,air flow meter,and then check your feul pressure and your fuel pressure regulator . Oh and try running your car at night looking at the plug wires this way you can see if a wire is grounding to the motor and some bosch plat +4's would be nice, i havn't found an rough idle yet that a $6.99 spark plug couldn't fix.good luck
p.s.if all else fails check compression
