Ok I have had my car for a year now. It is a 99 civic ex with a 5 speed. I will be driving it and the check engine light will come on. THe code that it is reading is a idle air control vavlve error. Now from what I have read the cars idle should raise and lower when you have a problem with the IACV. But it does not, what it does is every time I touch the gas pedal the car kind of jerks and then it will do the same when I let off the gas pedal. But if I push in the clutch it will not jerk when I let off of the gas and push in the gas.

So I took off the IACV and cleaned it really good. It still did the problem. So I broke down and got a new one for 170 and put it on. It still does it. SO I dont think that it could be the IACV.

It also starts to do this problem and throw the code when I make tight corners like u turns.

Could this have something to do with the transmission or the clutch. It is driving me crazy I just cant find out what is wrong, does anyone know a solution?
