im running a jdm b20 in my 95 g3 teg
and my idle jumps from 1000 to 1500 sometimes it will smooth out but then it idles at 1300 i know it isnt a vacum leak or intake manifold leak the car runs great but this vroom vroom crapo is annoying as hell please help me fix this problem

i need some

 

the idle screw is all the way in and it still does the same thing im thinking about putting the crv throttle body on and see if that does anything

this is starting to pi$$ me off

 

check for codes then if none replace your coolant temp sensor (not the 1 wire one) that is most likly your problem

 

no codes that i know of r u talking abot the sensor right below the distributer

 

it might be that you car will idle at 1000 then the fan will turn on and it will go up to 1500 then the fan goes of and it goes back to 1300
