If no improvement after cleaning MAFs, I'd clean the TBs. More complicated than cleaning the MAFs but not all that difficult.
Not sure what I'd try after all that.

^^^right process. I would also check your rear diff bushing. If there’s black fluid on your diff cover the stock rear diff bushing if toasted. Could explain your shudder. My Z also lost power but once I cleaned the mafs and throttle bodies extremely well I have had no issues
