I’m having the same exact problem, took it to the shop to have the computer read. It said bad tps and mass airflow sensor, I changed both and same problem, I have good fuel pressure, it doesn’t bleed pressure off, I’ve also changed coil packs. I don’t know what else to do

10 amp fuse #37 for the a/c may be the cause if it is blown.
