Cleaned MAF, now rough idle

I just cleaned my MAF sensor using CRC electronic cleaner as a preventive measure and now it is idling rougher than normal. Also cleaned the AEM air flter and ran a bottle of Lucas injector cleaner around the same time. Fuel filter was replaced less than 10k miles ago and I only use Top Tier gas.
Anyone else had this problem?

I guess the PCM just needed to re-learn the new air flow. Seems to have leveled out now and much better response. Wasn't visibly very dirty but did have 36K miles on it before the cleaning. Thanks.
