Code P0102, idles rough

Good morning,

I would start with a compression test for the rough running to be sure there is nothing wrong internally in the motor.

As far as the 102, it is for the mass air flow circuit.

First, you cannot clean a mass air flow sensor. The carbon gets burned on the sensor end and there is no cleaner that can remove it.

Below are possibilities for the code.

The white/red wire is fused controlled. Make sure it has voltage with the key on.

You are welcome.

Always glad to help.

An easy thing to try is to uncork the exhaust at the flange from the exhaust manifold. Code p0102 could be circuit related or condition related, like not enough airflow across the mass airflow sensor due to an intake leak or an exhaust restriction.
