2002 Ford Ranger Edge 3.0L 87k
Truck started stalling and jerking badly on the way home from work at 65mph on the interstate for about 30 seconds and then it ran fine for the remaining 20 miles home. I got home and plugged my reader in and got P0171 and P0174 pending.
I know those codes can mean a lot of different things with bank 1 and bank 2 system lean and as per the usual with my vehicle problems, my work schedule has me going seven days a week so I don’t have time to trouble shoot myself. I have recently replaced the MAF and the IACV as per the last trip to the shop with the same codes. My mechanic said all of the O2 sensors on my truck are brand new as well(previous owner had installed). I know new components can fail prematurely, but I’m curious as to what else could cause this again within a year of it being fixed the first time(same codes previously).The mechanic checked the fuel trims and pressure on the last time in his shop and said that all was fine and that my fuel pressure was just a tad high actually.
