Got a problem with the 4kq 2.5t. At 6-7 PSI boost the engine cuts off, smoothly not abruptly , I had a similar problem with the 5kqt when the top IC hose blew, but I've checked all air hoses and they look to be fine, the fuel pump is very noisy, can a loss of fue pressure cause the enigine to peter out like this?? Any help would be greatly appreciated Scott
