C5 bogs down when trying to accelerate quickly
 

I am going crazy just did plugs/wires basic tune up stuff cause once in a while when I mashed down the gas pedal it would hesitate then go now it totally just bogs down . I ohmed injectors all the same ( injector connection said they were good , fuel pressure holds at 58+ can't get any info on how to check the 6 pin throttle position sensor . No codes by the way

Clean the MAF. Possibly gummed up and isnt sending the right signal to the ECM to give enough air fro the fuel rate coming in.
