Ok so not so long ago i blew my headgasket and i replaced it but ever since its been idling funny idk if i flipped some wires ir something. When the car is cold it idles low like 600 then as its warming up its starts creeping up eventually reaches 1600rpm so is there any way i might have mesed anything up.
@fric frac HAPPY???? lol

 

Could be a vacuum leak, mis-adjusted TPS, mis-adjusted idle screw, non-functioning air regulator...

Check those for starters.

 

I checked the vaccum lines and found one that doesent seal as good and can hear a hissing around it it sems that the hose is allitle bigger. i replaced it and helped allitle now it only goes to 1500.The idles swrew is turned all the way down and i did install a new tps and tried messing with it but cant get right.

 

Are you running rich perhaps? Try taking your AFM apart, and leaning it out. Turn the gear clockwise. But be careful when you loosen the phillips screw, that you don't let the gear come undone. Try that and get back to us. There is also a write up on how to rebuild your AFM. It is a sticky on these forums somewhere. Good luck man.

 

Do i take it apart from the bottom or from the side cus the side cover is siliconed on i guess the previous owner lost the screws or something. My AFM has a adjusting screw on the is that used to adjust the mixture?
