p0171, p0174 after I changed my t elbow
Ok, so my little t-elbow bleeding thingamigigy cracked and antifreeze went everywhere, luckily I was only 1 mile from my house. I happened to have a extra one and I replaced it and bled the system. Soon after, the codes p0171, p0174 popped up. Cars running fine, temp is around 185-195. I cleared the codes but they came back up a few miles later. Anyone????

Why would the system be too lean after I replaced the t elbow bleeder? Do you think it could be a vacuum leak, possibly at the elbow? I had to cut the rubber to reattach to the new bleeder, both ends.Narpy's Grill Mod, Suspension Rods, Ultra guage, wrangler Goodyear duratracs 265/60/18, new thermostat, diff oils changed, brake switch new, aluminum rack floor, LED driving lights in foglights, rear camera, just need gvif unit, next on list!

Perhaps it's unrelated but I'm afraid I know very little about the petrol engine. Come to think of it, I don't know much more about the diesels!

check for air leak at and after the air mass meter, its reading to low a flow, hence weak fuel level,
try giving it a clean and re check all flexible joints at the jubilee clips FFRR SC 4.2
