my idle stays at 1300 rpm with the idle screw locked all the way off if i turn it a bit up is at 1400 rpm is this normal i have a 8lbs fly and a smaller lighter crank pulley and full 2.5 exhaust .. second thing is i know the rpm suppose to be a bit high with mods but will this hurt the engine

Normal idle speed is just bellow 1000rpm when the engine is warm. Is the fast idle (when the engine is cold) speed high aswell or is it the same as standard ~2000rpm??

Having a high idle wont hurt your engine but it will unnecessarily waste fuel and be loud.

the cold idle is at 1200-1500 engine warms up goes to 1300rpm wen ac is on 1100 rpm, someone told me to check the pcv valve??

Any leaks (indeed PCV, EVAP etc.) are easily able to get you up to 1300 rpm.

I sometimes had a TB plate not closing of properly... one time it caused 3000 rpm! (Ok I have 70 mm TB which is overkill, but still). Check TB plate closing position as well, sometimes TB cable is just too short.

it was the idle speed motor the 3 wire notorious for giving problems denso made for honda an toyota corolla ae111 thanks for all the help
