Ford Super Duty (1999-2016) :: V10 F250 - Code P0172 - Bank 1 Running Rich
What may be the issue with my truck. Drove earlier in the day and hauled trailer. Ran fine. Got it home and once I unloaded trailer and went to start up truck again it died a minute into backing up. I tried to restart and turns over but dies in 3-5 seconds. Tried again a few hours later and next morning and same thing.
Pulled code and came up P0172- Bank 1 running rich. I had replaced the Mass Air Flow sensor a few months ago. Since it was still under warranty I went and got a new one in case that was the issue, but didn't fix. When I try to start it smells like gas. Sounds like fuel pump is coming on fine. Checked air filter.
Of course is still hooked up to the trailer and in a tight spot in the yard at the moment so anything basic/inexpensive I can try myself first would be great.
Prius (Gen 2) :: Code P0172 And P0304 - Cylinder Number 4 And Fuel Bank 1 Location?
Having some idling issues. Pulled codes P0172 and P0304. Basically running rich on fuel bank 1 and misfire on cylinder number 4. My question is what is the locations of each...? From what I have read number 4 cylinder is closest to the drivers side and fuel bank 1 is on the passengers side. I have changed the MAF, plugs and checked the ignition coils. All looks to be good. I am guessing possibly fuel injector?

Well I got the ubiquitous "Bank 1 Too Lean" code this morning. Yesterday I changed out the PVC Valve, Elbow and Hose assy.
I changed out the hose from the intake to the canister purge valve on the firewall next to the master brake cylinder, that one was like dust.
Today I'm changing out the rear O2 sensors, but I may change out the fronts when they get them in (very rural area hear).
I'll keep looking for vacuum leaks and change out the MAF sensor. I hate to think it may be the intake....
Ford F-150 - 1997-2003 :: Code P0340 - Cam Position / Bank 1?
The p0340 code is the cam position right? Ready says bank 1.. Is there 2? Where the bank one is? And do I need to get on tdc on cyl one first or not?

Ford F-150 - 1997-2003 :: Vacuum Leak / Bank 1 Is Slightly Higher Than Bank 2
I am in the process of trying to chase down a vacuum leak on my 2003 F150 with the 5.4. I have checked all lines and cannot find it. I decided to check the long term fuel trim and noticed that my bank 1 is slightly higher than bank 2 (screenshot attached). Is this enough to assume the leak is on the bank 1 side?

I've been having this problem since I've gotten the truck about year ago. it has very high long-term fuel trims and it seems no matter what I do I cannot get them to go down my fuel trims at idle are 39 Bank1 and 33 bank2 they go down to around 12>7 while driving what could this mean. And even weirder occasionally I get Bank 1 or bank 2 too lean codes at idle when cold starting???? 1997 Ford F150 4.6 ......

Just started the truck after not running for a few weeks and drove around fine. Looked down and suddenly a CEL was indicated. Checked it with my Edge Evolution diagnostic mode and Code P0161 came up 2nd bank downstream heater circuit fault. I've also have an exhaust leak in the right passenger side exhaust manifold for about the last year. I've been waiting to install my newer 03' used engine when time and funds permit.

I have a 2003 Ford Taurus. It has been running rough for awhile. It doesn't happen all the time, alas. I took it to my local repair guy. They first said, oh this happens when the AC is on. But I knew it happened otherwise.
The check engine light came on yesterday, blinking, but didn't stay on. And it was running rough. Check engine light came on, on a Sunday so I had to wait until Monday to bring the car in. They just called and said they can't find anything wrong, ran it on the computer, says it's running fine. I said, did you check the spark plugs, wires, etc? (I am good at googling, to be armed with some kind of info)
I am thinking they just put it on the computer. I suppose it has to be running bad to show anything (?) and even then, it's no guarantee. Anyway. It seems like I am "sentenced" to driving this car until it strands me, catches on fire (I read about that possibility and I have on occasion smelled something burning), or if luck has it, when it is running rough, and I bring it in while it's running rough, the computer finds the problem.
Ford F-150 - 1997-2003 :: Shaking And Idle Bounces Between 500 And 750 - Codes P0172 And P0174
2003 f150 5.4, 4x4 ... Truck is shaking pretty bad, idle bounces between 500 and 750, and its throwing p0172 (rich on bank 1), P0174 (lean on bank 2), and it looks like a misfire on cylinder 8 judging by that power graphy thingy. I'm going to check for a vacuum leak tomorrow on the PCV.

I have a 2000 F150 4WD 5.4 running Extremely rich to bank one. The O2 sensors for bank 1 are reading lean(0-50 mV) Bank two is completely unaffected. New plugs in Bank one, 3 new coils in bank one, all pvc lines checked with good vacuum. Previous codes : P0171, P0301-3. The Truck will barely move. Would a small leak up stream of the O2 sensors cause this?

2002 f150 4.6l v8... Truck is misfiring and the exhaust is smelling very rich, I have new coils and plugs, it also idles rough and stalls if i let it idle for more than a couple minutes. Could it be something with fuel delivery system?
View 1 RepliesFord F-150 - 1997-2003 :: CEL On - Bank 1 And 2 Lean?
What does this mean?? The o2 sensor(s) is reading lean?? 2001 F150 4x4 5.4
There was also an evaporator system code, but I think maybe someone left the gas cap loose? I unhooked the battery and it cleared everything. Truck started fine for a few tries. Will have it driven tomorrow to see if codes come back.
My reason for this is it was getting hard to start. I confirmed that fuel pump relay was not coming back on when cranking every time. Randomly it's fine, other times it won't start. Noticed it had CEL light, had it read at local Azone.
Don't know what to do about the "lean" issue? What would tell the pump relay to NOT turn on?
I removed the cover from the relay and inspected points, they were fine. Check with ohm meter=good. Watched it function without the cap on it. Would prime every time, but not come on when cranking every time.
Ford F-150 - 1997-2003 :: 2002 5.4L - Lean Bank 2 / EGR Insufficient
My truck is a 4x4 lariat, I've replaced both dpfe valve and egr, and the intake manifold gasket. Still getting the egr insufficient code. It went away from a few months after replacing the intake manifold gasket but has returned. Where do I go from here? I vacuum tested the egr and that's working fine. Should I buy ANOTHER DPFE valve? Where do I go from here I'm desperate.

I have a 2000 f150 4.6 that would not run on bank2 ( the drivers side), even though the injectors and coils are all firing.While I was troubleshooting the problem I notice if you unplug the camshaft sensor and restart the truck it would then run on bank2, but the idle is rough.Can the PCM be the problem here. The only dtc codes are p1000, there are no misfire code at all, and it dose not show a misfire on the scantool data so I am lost.

I have a rough idle. I have replaced upstream o2 sensors, plugs, wires, fuel filter, dpfe sensor, cam sensor, and cam synchronizer. This has only moderately improved my problem. I still have the right bank, left bank too lean codes. Could it be something as simple but hard to find as a vacuum leak?
View 8 RepliesFord F-150 - 1997-2003 :: Codes P0304 And P0316 - Lean Bank 1 And 2
2003 F150 v6 2wd 170k ... For a year I've only had codes P0171 and P0174 (lean bank 1 and 2). I was told it wouldn't hurt anything... I think now I should have taken care of it.
Anyway 3 weeks ago my truck started running a little rough. It was sputtering and had trouble getting up to speed, sometimes also the air switches from vent to defrost until switch gears and rpms go down. It gradually got a lot worse over 10 days while part was otw. A week ago i changed MAF and cleaned the black thing it's inside of. It started running better but still not good. I pulled my small trailer 2 days ago and it got worse after dropping the trailer.
Today checked codes at AZ and lean codes are gone and have p0304 (#4 misfire) and p0316 (crank sensor problem). Is this related.? Also Right before all the trouble I changed battery and alternator. Also i read online that MAF needed 2 weeks to relearn the way I drive to get correct gas/air ratio? Is that correct?
Also I read so many different things I needed to do during installation... Some say I need to turn key to the on position after unplugging old MAF then plug new one in... turn key to on position 10 times, Rev up engine, drive it rough for the first 2 minutes... etc. Is there a correct way to do it or is it vehicle specific?
Should I start by changing spark plugs and coils? The guy i bought it from and trust said he changed spark plugs right before I bought it. Will it ruin truck if I drive it? I've read so much but everyone says so much different things on the same topic. I'd what to start with or if this is related.
Ford 7.3L Power Stroke (1999-2003) :: IDM Failure Code And High Side Open Bank 1 And 2
Today I just installed a brand new IDM and after running the Injector Buzz Test test, I received codes: P1298 Injector Drive Module Failure, P1293 Injector High Side Open - Bank 1, and P1294 Injector High Side Open - Bank 2. How a new IDM could throw these codes?
When running the KOEO test I received codes P0605 Injector Control Module Read Only Memory (ROM) Error, P1298, P1293, & P1294.
My engine is still missing but the engine is running a heck of a lot better after replacing the IDM and injector 8 has a rotational velocity of about 3%
