Try adjusting your idle. Your idle will always be high when you first start your car. So when it gets warm it will drop down to normal idle. If you aren't satisfied with your current normal idle, adjust it higher. Their will be a screw on your throttle body to adjust it.

900RPM range is about my normal idle but then i was wondering why is it going lower like around 800 RPM range.

i know where to mess with my idle screw but then was wondering if i have any other problems

also my car misfires sometimesi was told to change my spark plugs since im running NGK irdiuam plugs and they can cause it to misfires. is that correct?i was told to run with copper or platnuim

sorry for the spelling

My original diverter valve (turbo xs type-h pos) would only open at around 6 psi or so, once the engine warmed I believe it would have a hard time sucking through the slowly spinning compressor. Loosening the spring on the diverter so that it opened at idle and eventually changing to a Forge® diverter helped considerably. My idle is rock solid at 6-700rpm once it gets out of warmup.

Stock idle with the tps hooked up is 800. To adjust the idle you use the IACV, idle air control valve, not the throttle body at all. The IACV is on the back left side of the intake manifold as you're looking from the front. Simply turn the screw counter clockwise to increase.

you should be either running bkr6 or bkr7 gapped to .28.i suggest getting a set of bkr6.. as it solved my idling issue

i use to run around 700 but when i fixed 7 leaks threwout my whole intake system now i am about 900. and i run bkr7iex.

My idle fully warmed up is around 700-800 (kinda hard to tell sometimes) but i think its normal for my car. I run the ngk 7 iridiums. If the spark plugs don't work then try changing the plug wires. Start your car at night and see if there are sparks jumping out of the wires onto the valve cover and what not. This means to replace..
