i got some possible causes last time i asked this and tried all of them. right now my idle while driving is 1300-1400rpms when iam at a dead stop. i checked the slack and tension on the throttle cable, changed TB gasket, changed all vacuum lines on mani,checked idle adjust screw, checked for throttle plate sticking,cleaned my IAC valve and its still the same.

what else could make my idle while driving do that? and when im in park(auto) it fluctuates from 800-2000-800-2000 etc.

allready got new plugs,new wires,new cap,new rotor

this is so urking.

car is a 96 civic ex auto.

please let me know whats going on if you can think of anything.

thanks
james
