Hello everyone, I've got a couple minor problems I'm hoping someone here can shed some light on. 1. I own a 2005 Ford F-350 single wheel regular cab with a 6.0L and 125,000 miles. Whenever I start pickup for the first time, after glowing plugs, it will start, but only run for a second before stalling. It'll do this 4-5 times before I'm able to get it to start and stay running. Once truck is warmed up, it will start and stay running like it should. Anyone ever encounter this before? 2. Also antifreeze goes down slightly over time. Doesn't leave puddles, and doesn't seem to smoke abnormally. The other day I saw a little antifreeze on the contraption located on passengerside firewall behind A/C canister. Seems to be some sort of heater core. Is this thing the dreaded EGR cooler, everyone is talking about, and if it is the culprit for my missing antifreeze, how much $ to fix it. Any ideas would be appreciated!! Thanks you.
