P0351 and P0356 cylinder 1 and 6

Sun, 26 Apr 2026 04:10:39 +0000

Recently I purchased a 2006 E250 with a 5.4L engine and about 153k miles. I’m aware I probably overpaid, but I didn’t mind since these vans have a reputation for being solid and long-lasting. There was no check engine light at the time, so I thought I got a good deal.

Unfortunately, about halfway home, the check engine light came on 🤣. I was pretty shocked—I guess I got played by the seller. Surprising, right?

The codes I’m dealing with are P0351 and P0356 (cylinders 1 and 6). So far, I’ve replaced the ECM, coils, and spark plugs, but the issue is still there. One thing I’ve noticed is that when I clear the codes, the van runs perfectly for about 3 minutes. After that, the codes return and it starts misfiring again. If I clear them, it runs fine briefly, then the cycle repeats.

Does anyone have any idea what might be causing this? I’ve seen suggestions like a bad alternator, faulty connectors, or a grounding issue. Any help would be greatly appreciated—thanks in advance.

1999 Ford E-150 Econoline "Chateau" V8 Triton 4.6L VIN: 1FMRE11W4XHA22592 Power steering HP Line

Sun, 29 Mar 2026 13:10:47 +0000

1999 Ford E-150 Econoline "Chateau" V8 Triton 4.6L VIN: 1FMRE11W4XHA22592 Power steering HP Line.

The issue I'm having is a major leak from the steering pump to power steering HP Line connection. The frustration I'm having is the installed line and the configuration does not match the power line available from any source (see here: https://www.rivercityfordparts.ca/oem-parts/ford-motorcraft-trade-power-steering-pressure-hose-psh26?srsltid=AfmBOoovUO00KimH0_5h13lAZghX0mPAD4JAVRaGkYH5pNVqnPzozoHs). I can't figure out how to uplaod a photo so I'll have to describe. Where the available replacement has a long metal pipe ending in a 180 degree bend, the line installed on my van has a short pipe with no bend. Does anyone have a similar van and can send a photo from underneath the engine showing the power steering HP line? Also, the space is very limited so I can't get the line off. Any help or advice would be much appreciated.

2014

Sun, 28 Dec 2025 13:04:50 +0000

We have a 2014 E350 cutaway ambulance that has broken hood hinges on the upper side. 3 on the right and 2 on the left. There is no body damage and the hood operates as it should. There is no specific event that indicates it is broken. They are just broken when the hood is opened. Has anyone ever encountered this? I worked in a body shop for years and have never heard of hood hinges breaking.

99 E-150 V6 no start when warm outside

Fri, 12 Dec 2025 21:16:28 +0000

I have a 1999 e-150 with V6. Van starts and runs great when it’s cool outside. As soon as it gets around 80 or so OUTSIDE, it won’t start. You turn the key on and the engine won’t even try to turn over. It acts like the battery is dead. Just to make sure I am clear. I am talking about the ambient temperature outside, not engine tempt. And advice would be greatly appreciated!!!

Help with air con ducting

Sat, 25 Oct 2025 21:10:17 +0000

I have a 2016 E Super Duty, actually a Winnebago 25 foot RV. Basically an E350. The gasket from the cowl air intake for the HVAC system has deteriorated and is letting hot engine compartment air as well as mice into the system. This is the foam gasket that is on the right side right under the cowl behind the windshield washer fill and a lot of A/C piping.

How is that gasket replaced? It looks like its in a pretty inaccessible area.

5.4 transmission swap

Wed, 01 Oct 2025 09:17:55 +0000

I have a '97 E250 with 5.4 and E40d transmission. The trans is caput. I've had bad luck with re-builds in the past and I'm seeing some attractive offers on Marketplace for low mileage used tansmissions. So, the question is, what other years will swap right into my '97 with no modifications?

2017 ford e450 6.8 super duty will not start.

Thu, 22 May 2025 18:09:25 +0000

I have a 2017 ford e450 6.8 super duty chassis, it has a Jayco RedHawk right built on it, bought it three years old, never had a problem with it, when I’m not using it I start it ounce a month and run it for an hour or so. Now my problem, I went out to start it up and battery totally dead, tried to charge it, could only get up to 8 and a half volts. I went and purchased a brand new Die Hard battery, checked and cleaned both poses and battery cables, went to start it, all it would is make a bump to start two times while holding the key, it would not start, after trying, I don’t know how many times it would start and run for about five seconds. Now it has only done that about three times, I was researching other forums and have made a few change outs, now the code I did get off the vehicle was a P0607. What I changed out was the starter, fuel control module, ignition switch, used a contact spray on the main control module connections I also cleaned a number of ground connection points. I tried some starting fluid to see if it would start, no go. With all the computer controls, the things I haven’t changed is the in tank fuel pump and main control module, also after it fails to start the parking P light blinks. I’m 78 and am limited on some things I can do, I want to check the fuel tank pressure but can’t locate a fitting to use on this e450 as it has no Schrader connection point, any help will be appreciated please.

Battery Draining when using a/c

Wed, 02 Oct 2024 23:17:52 +0000

Anytime I use my air conditioner The voltage drops from almost 14 down to 8.2 and then I have to charge my battery again or else. My van won’t start. My question is would this have something to do with the AC clutch fan not working or would this be an alternator/battery issue? Thank you.

A/C not blowing in front.

Thu, 25 Jul 2024 17:12:02 +0000

2000 e450 : No acceleration at times, skipping / jumping

Sun, 21 Jul 2024 08:02:00 +0000

My 2000 e450, 7.3, turbo diesel was an ambulance that I've converted to a food truck. I've had it for 6 years and it has recently started lagging when accelerating at times. It kind of feels like it's fighting against itself to move.

When it first started I replaced the brakes, rotors, hoses, bearings, seals, and calipers. Actually, a couple of the calipers a couple of times because one was defective and the other seemed to be running 30 degrees hotter than the other 3 and smelled hot. The ABS module was replaced, also, when I first bought it 6 years ago.

When the mechanic scanned it today there were no codes. However, he questioned why the ABS result showed the right and left front brakes results but only showed one rear result (it didn't specify right and left, I mean - just listed as 'rear'). So, should it have?

On the other hand, last week when it acted up my friend said he saw white smoke come from the exhaust. I was on a flat road, which is where I've sporadically noticed it lagging, but today I was entering the Interstate via an inclined ramp and it was really struggling to make it up. At one point it shuttered / skipped along but didn't stall. I made it home but am not certain of the issue.

Pretty much I've been thinking the brakes have been locking up but now I'm starting to wonder if it might be the glowplugs. I've not replaced them yet and read that the smoke, lagging, struggling on inclines, and skipping could be a misfire.

Any help is appreciated. Thanks

2016 E350 Error Code P0751 (Shift solenoid A Performance or stuck off)

Wed, 17 Jul 2024 02:25:28 +0000

Greetings,

I'm just looking for a little direction with the transmission in my box truck. It's a 2016 E350 5.4 flex with 62K miles. Only one mile from my warehouse, I heard a pop (not too loud) and the transmission basically went into neutral. After dragging it back, I discovered a P0751 code with my scan tool. I did a bit of research to find that it could possibly be a tad difficult to diagnose. I decided to order a complete solenoid body with all 7 solenoids. I installed it with a new filter and cleared the code. Now, when I try to shift it forward or backward, it seems to move slightly, but doesn't engage into a gear. I've checked the resistance on the solenoids and they all seem to check out. Any thoughts or direction? And what could have Popped? Thanks, Jim
