Won't Idle Fir More Than 15 Seconds

Dies after it runs for 15 seconds cannot accelerate to keep it running, here is the weirdness, I removed the turbo cooler to test fuel pressure, ignition spark, fuel injector pulse, all tested perfectly, with the cooler off the car idles fine

If I add vac to the waste same results dies with cooller installed.

If i apply pressure to the waste with cooler installed car dies

Removed cooler and ran a straight hose from TB to turbo out, car dies, remove the hose car idles fine

Dropped exhaust after 1st CAT same results ( CAT bolts straight to turbo) CAT looks clean from bottom side

No codes, no sensors look out of specs

Thanks for your help

Try pulling the intake piping or air filter. If the turbo can't get air it cant pass it on.

I’d be looking to see if there is debris on the maf sensor

Dan was correct, rodent nest particles were found in the MAF sensor Not sure how to close this, even read the Instructions, I don't see a resolution button

I'm thinking the same intake clog
