Method to diagnose throttle actuator

Anybody know the best way to go about determining if you have a faulty throttle actuator? I've been chasing TPS and MAF issues recently and am still having trouble. Using inpa is there a test I can run or an expected behavior I can check? I've replaced the pedal and I have a new maf and tps sensors coming next week but since I have limited time at home before I have to travel again so I'd like to get the actuator coming if I can figure out if it is indeed bad but it's not cheap either. I've found it for 521 shipped at Turner.

Car has 130k
replaced both tps about 40k ago preventatively
replaced pedal 200 miles ago
maf on order as it failed 300 miles ago so it's currently running without maf
tps on order just in case as they're cheap

Car is throwing the following codes as well as expected maf code since it's unplugged. The car feels great until it hiccups and throws the eml,brake, engine lights.
