GSLEX99

Whats up guys and girls i just got a 92 lexus sc400 the other night and it has a idle problem. It sounds like its got cams but it does not. And also it feels like its going to stall. I think its the iacv but I have no clue how to take it off and clean it, hopefully that would fix it. Did I make a bad buy. Idk wtf to do and how to fix this. Someone please help me out or give me instructions to what to do.

Thank you

check for an exhaust leak near or around the manifolds if you engine sounds louder than it should be.
what is the idle problem, does it dip, does it go up and down, or is it just low?

Your idle air control valve is most likey stuck either stuck open of closed. You might have something stuck or restricting air flow to your motor. I have a good feeling it is your IACV.Tap the top of the valve and see if it changes at all. Then if it doesn't react to that take it out and clean it then reinstall the vavle. IF there is no effect or it gets worse replace the vavle. I mentioned this on another guys thread that you posted in. Do you have a check engine light on? Where are you located if Florida cause if your close I can possibly help you out.
