my car started thrown a check engine i checkd it and it was for the tps so i orderd a blox tps from jhpusa.com i replaced it and reset the ecu now its idleing like crazy....so asked my boi he said to check the IACV and make sure the screw didnt back out it was all good so i reinstalled it and then every thing went to hell still idleing high and now its thrown out hella white smoke from the exhaust like the head gaskets blown but i just replaced the head gasket less than a month ago...and i tried unplugging the iacv while running and the idle droped from around 2200rpm to about 1500 rpm and my radiator is smokn now

 

take the iacv off and clean it out with brake cleaner ..also check it to see if it's working 12v power and a ground listen for a click (no click? replace it)...also check for vac leaks ,check the idle screw on the throttle body and make sure everything is plugged in where it should be...as far as the rad..have someone or you do a pressure check to see if it has any cracks good luck

 

what do you mean check for 12 volt and if no click replace it....and about the smoke only smokes bad when at idle or parked while driving its ok no smoke

 

take a hot wire and conected it to the iacv and a ground out the iacv ..like to the sensor...

 

if i unplug the iacv sensor it drops in idle rpm could my map or tps sensor have anything to do with it cause it all started happening when i replaced my tps cause of a 7 code from my ecu
