Does anyone know if I have to replace the intake manifold or can I try something cheaper first. I did see a little anti freeze leaked . Thank you for your time and consideration.
That code is for "Intake Manifold Runner Performance Bank 1". That does not automatically mean the manifold needs to be replaced. These are the common reasons for the code;
- Intake manifold runner control actuator failure
- Powertrain Control Module (PCM) failure
- Restricted vacuum lines
I'd start with #3 to see if it is as simple as a vacuum line. The other two are more complex and may require a qualified mechanic to be involved to troubleshoot.
