well, just recently my lsvtec has started to act up a bit. after the car is started up the idle loops until the car is fully warmed up. now that it is gettin cold in wisconsin, it won't stop looping. just wondering what the hell is wrong with my car. set up is b16 head with jdm itr pistons. does anyone know whats wrong???

 

If by loop you mean lope, it would be running rich and misfiring a little. Does it smell like it's running too rich?

 

check the map and tps sensors to see if they are connected right and not switched. Any codes on the ECU?
