i have been running fine with this car for 5000 miles. now all of te sudden its putty at idle. like when im at a light so i figured adjust idle air screw to raise the idle and i get a really high idle like 2k for a min then the up down up down idle till it warms up with high cold start idle what is the factory screw setting on a gsr t/b from the screw seated cause i didnt record wher it was. does anyone think otherwise why my car does this any thing other than iac

 

change the spark plugs, reset the ecu and check the tps also check inside the dist. cap.

 

how do i check tps
