My car is doing some strange things. I changed the valve spec as per the topic on here and there was no problem. Now the car has started to idle at 200rpm on the rev counter, it does this fairly smoothly. The vrc change over point indicated by the vtec LED has changed two it seems to have increase 200rpm to 5400rpm indicated on rev counter. This seems strange, can rev counters go out of spec. What do you think?

sorry posted that in a rush. I adjusted the valve specs tighter . How the car idles very low and the cam change point seems to hae changed though that could just be me. How do i increase the idle i have read about disconnecting the IAC valve then turning the screw on throttle body. Is this correct?

Thanks
