running rich....

[supra4ever68]

can this be caused by a leak in a intake hose?
what happens is on warm up it runs nice but after it gets to normal temperature i start hearing a pop from my exhaust and it just turns off...
if it can be because of a hose can someone please show me how i can pressure test the system from the turbo?? thanks!

well if it was a vacuum hose i would think that it would occur all the time rather than when the engine goes into closed loop. any codes?
