Our '04 Southwind with the Ford V10 started with minor hesitation last month but now it's turned into full P0171 and P0174 lean condition codes. Engine runs fine otherwise - no rough idle, no hesitation, fuel economy seems normal. Just these annoying codes that keep coming back.

I've heard the V10 has some common issues that cause these dual lean codes. Already checked the obvious vacuum lines and cleaned the MAF sensor, but wondering what the most likely suspects are when you get BOTH banks showing lean. Is there a systematic way to track this down, or should I just start throwing parts at it?

Really don't want to take it to a shop if this is something with known failure points on these engines. What would you guys check first? …more

Finally dealing with my Ford V10 throwing the P0171 lean code for the third time this season and I'm absolutely done with these guessing games. My Ford V10 with 60,500 miles threw this code during our recent trip from Maine to Virginia, and while there are absolutely no drivability issues - no rough idle, stalling, or poor performance - I'm terrified something catastrophic could happen on the road.

I've already cleaned the MAF sensor and had a local mechanic check for vacuum leaks and run a detailed diagnostic, which found no performance issues and cleared the Check Engine Light. The engine runs perfectly fine, but that check engine light has me spooked. What if I'm damaging the engine by driving it? Should I be monitoring for specific symptoms? I keep reading horror stories online about lean conditions causing engine failure.

I really don't want to get stranded somewhere or cause expensive damage, but I also don't want to cancel our upcoming trip to Florida if it's actually safe to drive. Has anyone dealt with this specific code on a Ford V10? What should I be watching for, and is it actually dangerous to drive with P0171 when the engine seems to be running normally? …more

During my continuity test on this dangling wire near cylinder #5 of my 2000 Fleetwood Southwind Ford V-10, I'm getting a reading but the wiring diagram shows nothing should connect there. Noticed it while doing spark plug maintenance. Can't tell where it came from or what it might be. What are the common components in that area of the Ford V-10 that typically come loose over time? …more
