Hi everyone, this my first time joining the evolutions.net.
I have a problem with idle air control valve on my evo4, and anytime I start the engine and once it get’s warm the RPM stays on 2000, and it doesn’t go down to 900. I bought a new idle air control valve with the assembly and as soon as I installed it, the engine RPM went up to 3000 which is worst than the older idle air control valve. I am not sure if it needs to be reseted? Has anyone experienced this issue before? Any suggestions would help. Thank you!
