Ford F-150 (2004-2008) :: Low Oil Pressure / Gauges Drops / Then Stalling
Jan 7, 2016
2004 Lariat. Ford F150, 5.4 Triton. Whenever I slow down, stop, or turn my truck will read low oil pressure, then all my gauges drops and it stalls out. I've taken it to my mechanic twice now. And twice he's replaced two sensors. Today I took it to Wal-Mart for an oil change and they said its probably why my check engine light is on code, T19. I've had that light on for 4 years now and this stalling out problem starts 3 months ago. So far its had regular oil changes, new air filter, two new sensors and im scraping money to throw at it. Hitting snow banks, other vehicles, and tree's... need to find the real problem before I go broke or worst kill someone in an accident.

I recently bought a 2005 F150 King Ranch. I had a 900km drive to get it home but only mad it half way and am now stuck. I was stalling every time I came to a stop and eventually lost oil pressure. This is when I stopped driving and took it in. The shop said it had a knock in the lower end and stopped diagnosing it there. I can now sell it for parts and take a big hit or I can try and patch it myself.
I am assuming based on my symptoms it is a spun rod/main/thrust bearing. The mechanic was not very supportive to narrow it down to anything other than replace the motor.
How many km might I get out of this engine if I pull the motor and replace only the crank and rod/main/thrust bearings. This will not be my daily driver so if I can get another 50000-100000 km off of that, then it will last me at least 5 years.
This is of course assuming that when pull it apart I do not find an other major problems such as bent or broken pistons and rods or scoured cylinder walls. I am not that experienced of a mechanic, so I am not that confident about pulling the heads off and rebuilding the whole thing.

I have a 2004 Explorer 4.0L v6 that I recently charged the AC in. The engine was rebuilt not to long ago so the AC was completely recovered (bought it from a friend), so I know I started fresh. I am not by any means a novice mechanic but, just dabbling into the AC world and have watched a ton of how to videos, and what not.
I went out and bought a set of manifold gauges as well as a vacuum pump. I do have the rear air on this one so it takes (correct me if im wrong) 56oz of refrigerant. I pulled a vacuum of 28 (mercury?) and it held it for a good hour so, I am pretty sure no leaks. I went ahead and charged the system... Compressor kicked on like normal, air got cold, and everything seemed to be going just like it should be. I went by just a random r134a ambient pressure chart NOT from ford.
I thought great this is going to be like new! Well, now the problem i'm having is in the mornings at say 65-85 degrees it blows ice cold. Once the sun gets higher in the sky, and it gets up to 95-100, it doesn't seem to be able to keep up, even driving for miles and miles. I noticed the rear air evaporater low side, doesn't seem to feel very cold either. Does this mean I might be over charged/under charged?
I have a video of the pressures at 2000 RPM, AC set to "max", both front and rear fans set to highest setting, windows down. At 31 seconds, the pressure drop is because I let off the throttle and let it idle for a bit, so you can see those pressures.

I have a 08 F150 king ranch and have a couple of issues. There is a strange sound coming from the dash behind the gauges it sounds like a computer hard drive clicking and the heater seems to be stuck on will not even blow outside fresh air.

2004 F150, 4.6 V8. I'm wondering if my engine control module is going bad.
A few weeks ago I got into it in the morning, turned the ignition on, gauges responded as expected, warning lights on, etc. After starting the engine, all of the gauges peg to the left, and sort of "tremble", as if they were trying to keep going past the stop. After 5 seconds or so, they move up normally. This happens every time I start it now.
Since this weird gauge behavior started I have had to disconnect the battery to clean the negative terminal. After reconnecting it started experiencing idle problems. It idles smoothly, hitting on all 8, but it wavers. I found instructions in the owners manual for "relearning the idle and fuel trim strategy". It's been a over a week since doing this, and it still wavers and throws a P0506 error periodically, which I have been clearing. Twice while coasting the tachometer has jumped up to around 2000 rpm and the engine cut off, like maybe it thought the engine revved and closed the throttle to "slow it down".
My question is, have I just not waited long enough for it to re-learn to idle, or is it possible the engine control module is starting to fail?

My truck was fine yesterday morning, but when I got in it after work, nothing worked. The power windows, radio, ac, gauges all stopped working. Everything else does - power seat, wipers, turn signals....etc. What is going on?

I just installed my Edge Evolution from my 2006 F-150 5.4 into my 2008 F-150 5.4. It is not displaying oil temperature. It just shows 0 degrees. why?

I had a loose bulb in my overhead interior light I tightened the bulb and now the gauges quit working the sunroof, rear window, air compressor, windows, radio and airbag warning flashes?? I checked the appropriate fuses in the panel fuses and the 30 amp breaker all good??

I have a 2004 F150 (New Body Style) with 5.4L 3v and about 266k miles. My Alternator finally bit the dust and my instrument cluster went from reading speed, temp level, odometer, RPMs to being blank and all needle gauges bottoming out on the "0" side. Removed Alternator and had it tested, found Alternator Failed tests. Ordered and Installed New aftermarket 110a Alternator. Battery was fully charged (13v) and passed load test out of the truck. After installation, started the truck with no problem, instrument cluster gauges all read normal when turning key to on position, after starting and let run, instruments and gauges blacked out and returned to "0". Battery was reading 13v and with truck running read about 17v. What could be causing this?

The battery light came on in my '04 F150 a couple of days ago. Terminals were in need of cleaning, so I took care of that. The next day after driving 50 miles to and from work, the battery light came on again, along with the ABS & Brake light started flashing. After shutting the truck off, it would not start.
Three days later, I have now installed a brand new alternator and battery, only to have the same symptoms pop up about one minute after start up. The warning lights are now accompanied by the passenger airbag light and all engine instruments needle sweep back and forth. Dash lights go dim and bright intermittently as RPM varies.
Do I need old fault codes cleared or is this a PCM issue?

My 2004 fx f150 with 177K miles is stalling (rpms bottom out) driving down the road and coming to a stop (coming to idle) and when trying to park. AND, its an intermittent problem.
Of course, not spitting any codes or CEL's. I've searched the site and there are multiple types of the same issues and solutions. Narrowed it down to either the dreaded vacuum line sandwiched against firewall and engine compartment, OR the cleaning of MAF, throttle body and IAC valve.

Here's the problem: just bought my o4 FX4 5.4 liter. When I test drove it, I heard the ticking noise but knew it was sometimes normal for these trucks so i paid it no attention. like others iv heard from, as soon as they changed oil the ticking noise got louder but in the last week it has randomly stalled twice at very low speeds trying to find a parking spot. the engine pretty much sounds like a deisel now and I am wondering if the ticking noise and the stalling is related.

I have a 2003 4.6l f150 164000 miles. While back oil pressure dropped to 0. Then chattering. Then up then down. I changed the oil and filter, then flushed the motor, then changed the oil and filter again. 1500 miles, no problems, no chatter. Then all of a sudden it happens again. Oil level good and clean. Oil pump?Pick up tube?

I have a 2005 5.4l f150. 105,000 miles. Recently While on a trip I experienced rough idle and stalling at idle. I drove it home 2hrs. The ride home was challenging. Poor acceleration, rough idle. Took it to the dealer and was told I needed plugs and I was 5qts low on oil! Not sure where the oil went. It hasn't been leaking and never seemed to burn oil in the past. They did the tune up. Picked up the truck. It ran fine while cold. Upon warming up it ran rough at idle and stalled just like it did before. Took it back, they said "you need a new engine. Upon warming the oil pressure drops indicating internal engine damage". I took it to a local guy he says replacing the cam phasers might fix it. What's the consensus, should I try the cam phasers? Look for some other potential problem or trust the dealer? (They did refund me for the tune up)...

I've got a 4.6 in a 2005, 178000. I assume the 4.6 in an E150 would be the same as the F150.
So anyways, Started and an intermediate problem where sometimes it would stalling when making turns, such as entering a driveway, making turns or going from reverse to drive. Now its turned into more of a problem with stalling, even while in just idle and not just in gear.
At idle RPM is sporadic from 300-900. Here is where I'm at New Fuel Filter. ECM is reading 38 to 41 psi fuel pressure at idle and when the throttle is pushed.
Took a chance and changed the belt since the old was a bit lose. Even ran the engine without a belt and there was no change in my problem.
I've removed the throttle body, just learned these engines don't have an IAC, they use and IAC motor instead. I don't know how to test that but I'm googling it.
Back of throttle blade is all gunked up so I'm cleaning that now. It has no codes btw.

I recently bought a 05 f150 with 5.4 3v and 195k miles needing some work. Ran great, just had a code for timing over retarded. Originally it had a cracked timing cover, so i took it off to replace and found broken guides and bad tensioners on timing. I installed new guides, chains, and tensioners, and cleaned phasers, and put back together only to find it ran terrible and had a phaser rattle. I then went in and installed phaser locks, which took care rattle but not the running issues. I can not figure it out.
ISSUES: My issues almost mirror what is said in this thread here, but this issue was never solved. [URL] ....
My issue is when started cold it starts right up, idles ok, runs ok, although a bit sluggish. Once its warm it stalls at idle, shudders when giving throttle in overdrive, and if you kick it down it will continually backfire, and slowly accelerate... it kicks down but acts like its only getting 1/8 throttle, just kind of hangs at the same rpm and slowly climbs in rpm. Sometimes it wont backfire as much, and sometimes the check engine light flashes. After it stalls at idle and you start it back up it sounds like it shudders/backfires for a split second then starts.
It is throwing many engine codes, but most are from the phaser locks. Throws code for timing over advanced on each bank (phaser locks lock them fully advanced), cam timing codes for each bank, and then a code that doesn't have to do with the timing, P2106. I am going to run some live diagnostics on it today and report back but I am fully at a loss.

I changed the oil on my 2008 Prius Touring in the weekend. I consulted the manual after the oil was changed. One mistake I made was to use 10W-30 instead 5W-30 recommended. The manual mentioned that it affects MPG with 10W-30. For the 270 miles trip I took right after, my average MPG dropped from ~46 to 45 highway. My short commute driving dropped from ~37 to 34. Comparison are made on the same roads with similar temperature and driving speed. Is that normal? Will it go back up after a while?

I have an 01 F150 Lariat Supercrew 4x4 with the 5.4 Triton. The truck has 222,000 miles on it. Recently, I have noticed that when I am stopped at a stop light/stop sign while in gear, the oil pressure gauge drops to zero and the light comes on. As soon as I let off the brake and give it gas, it pops back up to normal. While driving, the needle never moves and stays consistent until I stop again, and back down to zero it goes.
If I put the truck in Park, the pressure goes back to normal. Same with neutral. It seems it is hit or miss and does not do this all the time, but I just wanted to see what your thoughts are. After doing some research I am leaning towards an oil pressure sensor/sending unit.... The truck runs perfectly fine, I just want to make sure it is not something more serious.

I have an 2006 f-150 King Ranch with 103k miles and it was misfiring and then stalling when stopping at lights. Both cam shaft sensors and all coil packs were relaced then it was still misfiring. The head was recently replaced and now they are waiting on a new computer. When it starts misfiring it vibrates the whole truck and the engine light flashes. If you turn the truck off then back on it will run fine for about 50 miles. Im worried that replacing the computer is not going to fix it, what else could it be?

I've got a '98 F150.throwing codd 402, excessive flow EGR, also the oil pressure drops to absolute zero only when gear shifts but comes right back up. No knocking or other distress sounds in engine. I know I'm in need of an oil change. I already searched a bit and decided to swap out the DPFE sensor which I did purchase from the dealership. No code as of yet but what could that pressure drop be? Could a simple il change and filter fix that?

I have an 03 Explorer that had a starting issue. Long story short, it had no fuel pressure. So after testing the relay, I switched out the pump with an Airtex unit . All seemed fine...for a while.
Became hard to start again, checked Schrader valve with the key on, and not running, no pressure. Strange though, it would run.
So got the fuel pressure gauge on it. Turn the key and pressure will go to about 5-10psi and then drop to zero. Turn key off and on again, up to 5-10psi, then drop to zero. Turn the key to start and pressure goes up to 10psi, then starts, then goes to 30 while running and you can drive it around. Shut off motor and pressure goes down to zero.how the sending unit is supposed to hold fuel pressure and not release it? Is there some kind of check valve in the sending unit assembly that can be cleaned or does it need a whole sending unit with another pump? I already spent the $100 for the pump, and it is working if you can drive it!
