88 k1500 stalling problems

[RustyChevy]

I have an 88 K1500 with the 5.0L TBI 305. I have no stalling problems while driving. The only time it stalls and dies is at a stop. I have to keep one foot on the brake and one on the gas to keep it running. It doesn't run rough. It only does this at a stop or when I park. Any help would be greatly appreciated. Thanks

Does it have good idle cold when first started?

Any codes or check engine lights on running?

Check all vacumn lines and PCV valve and brake booster vacumn.

What is engine vacumn reading at Idle and at 2K rpm?

sounds like a bad TPS
