When you cleaned the MAF did you follow this process?

If not, I suspect the sensor is damaged and not reading the air properly that is coming into the engine. If this is all that you did, I would start with checking for codes and then replace the MAF if nothing else comes up.

If this does not solve the issue, I suspect you damaged the throttle body as you are not supposed to clean these one. Basically when you clean this throttle body with a chemical it can change how it reacts and the PCM does not respond correctly and it causes these types of issues.

Take at this information and we can go from there. Thanks
