When I stop at redlight or stop sign eng. Just stops, no running rough, just stops like I turned off the eng. The veh will start up as soon as I crank it. After a week of this a DTC pops up"p0174". So far I changed the fuel filter, cleaned MAF as best as poss. Sprayed brake clean around eng. To check for poss. Vac leak. Cleared the code. Problem still there. Any thoughts? Please dont say headgaskets!

Check fuel pressure with a gauge sounds low. Autoparts rent the gauge.
