Taking the MAF of isn't that big of a deal and it will give you a good opportunity to check if the runbber boot and vacuum lines underneath it are still in good order. I always take my sweet time and all it took me about two hours. And I cleaned the MAF, replaced the rubber boot and vacuum lines and connectors.
