Hey my car wont keep the idle at a constant rpm. It will vary from 1500 to 500 and will just start shaking. I know it should vary a little bit once it gets running but i doubt it should be this much. I ran some engine cleaner through it and changed out the spark plugs and wires but it didnt help. Any ideas? Thanks guys

 

check your IAC

 

i took off my iac and cleaned it and everything and put it back on, I also changed out my PVC valve. Im still searching for ways to do it but i dont wanna try expensive stuff like the MAP Sensor untill I know there is no other choice. Thanks though, any other ideas?

 

not PVC i meant PCV its not a stupid pipe lol

Is your car stock? I believe some mods can cause this to happen.

 

changed your fuel filter lately? Your problem could a vacuum leak
