I just replaced the Idle control valve because the idle would rise suddenly and stay up.
The replacement did not fix the problem.
After the engine has fully warmed up, it will start racing up uncontrolably. Only way to bring it back to normal is to shut down and start again but it only lasts for a few minutes before it goes up to the roof again.
Can the EGR valve cause this kind of problem?
What would be the first parts to test?
Thanks for your help.
I will gladly pay up to 25.00 for a sound advice.
I will pay after I get a chance to test your recommended solution.
