I’m guessing you have the common P2004 code, which stands for ’Intake Manifold Runner Stuck Open.’ While the manifold runner valve is a common reason for this code, there are other potential culprits as well. A mechanical problem with the intake manifold itself is one possibly cause. There could also be a problem with manifold valve control circuit and/or feedback circuit. The power and ground circuits must be intact as well. Since you’ve already tackled the low hanging fruit, I recommend having a professional fix this issue for you.
