car runs like crap at idle???help

[sr20detRcr1]

s13 redtop SR20

to start the car i have to let the pump prime, crank it , then let it prime again and it starts right up

once its started it will idle normal for 20 seconds or so then it jus dropps to about 700ish from its normal 940ish, its only when coming to a stop or at idle it drops like this.

could this be my iacv ****ting out?

940 seems a little high for idle anyway, 700 seems normal. now the fact that it drops from one to the the other is not so normal. what kind of setup are you running.

could e your iacv try cleaning it for starters

make sure the orange wire on the gauge cluster plug behind the glove box is hooked up properly and receives power during starting only
