Ford - Explorer :: 1998 - Running Rough - Cut Out - Got PO453 Code - Changed Gas Cap But Nothing?
I have a 98 sport 4.0 i bought awhile back and its been running rough.. When driving it seems to cut out.. I had it scanned and it has code PO453 which is pressure sensor.. I was told they replaced the fuel pump when i got it.. After driving and i get out i can smell gas on the drivers side.. I replaced the gas cap but no change.. I was just wondering about this code and what i should start with first..

1997 F150, 4.2L V6 200k miles. Truck has been running fine. No CEL, or anything. Stopped and filled up the tank and within 10 minutes of leaving the pump, the CEL came on. Code is P0430.
I drive this truck 60 miles a day. It's shown no signs of any issues until the light came on today. Just curious if some bad gas could cause this or am I in for CAT replacement...
Ford F-150 - 1997-2003 :: 2000 - Idling And Running Rough On Acceleration - P0171 Code?
My daughter returned from college with her 2000 f150 4.2 idling and running rough on acceleration. It is throwing a P0171 code only. I replaced the isolator bolts/plenum gaskets four years ago because of a P0171 & P0174 codes.
So far I have replaced the MAF, new PCV valve and elbow, checked all obvious lines for vacuum leaks (though I suspect a leak somewhere still). Also, a quick check of the plugs show some lean color/deposits on the drivers side only. Any thoughts or troubleshooting I should try next?
Ford F-150 - 1997-2003 :: 1999 - Misfire / Running Rough - Code P0305 And P0174
Here is my situation : I have a F150 1999 4x4 ext cab with 326 000 km. A little while ago I got a P0401 code so I decide to clean the TB first and at the same time change plugs and wires since they were overdue. The same code came back and a misfire. Ordered EGR valve, DPFE sensor and selenoid. Realize that I had ordered crappy plugs by mistake. I change all plugs. Had to wait for the EGR valve and others to arrive. I drove the truck for a while since I did not have the time to change the valve and others, during that time the misfire did not come back. Yesterday I change the EGR and others. Today I get a truck that runs really rough and got new codes , P0305 and P0174. I'm really confused now on what should be my next step, should I change the coils, can a P0305 cause a P0174. Should I change vacuum hose going to the EGR , selenoid and DPFE.

I've got a 2000 f150 with a 5.4 and 135,000 miles. The other day it was driving fine then i stopped and got gas and after that it was boggy and running rough so i thought bad gas but i ran through that gas and got more at a different store. The cel came on i got it checked it was misfire cylinder 1 so i put new cop, spark plug, and injector. Unhooked the battery and then the light came back on so i ran the code and now im getting a p0171. I checked the pcv and sprayed around the intake and vacuum lines. I also checked the pcv hose and elbow in the back and i found nothing its a fairly new hose. So, it does run rough it shutters a lot.

View 2 RepliesGrand Prix :: 1997 GT Running Extremely Rich And Pressure Build Up In Fuel Tank
I'm having this weird problem with my car, 90% of the time it will start to run rich, until it reaches normal temp, to the point that I can smell it coming out from the exhaust. LTFT is at around -15% and it seems to go down after cruising for some time but will go back to negative at idle. My first suspect was the FPR so I checked it and found no gas smell on the vacuum hose, then I decided to run the engine with the vacuum hose disconnected and see if any fuel would come out, 5 minutes later and it was still dry.
There is a chance that the MAF sensor is bad, I'm 90% sure it is, because it will sometimes read 2.9-3.1 gps at idle and according to the rule of thumb of 1gps per liter of displacement, it shouldn't go that low but I might be wrong about it; I disconnected the MAF and the smell was still there, today while driving it was reading 5.45gps (A/C was on) and the smell was still present; car also feels sluggish from time to time only at normal operating temperature (which I assume is because of it running rich).
There is also a vibration felt through the steering wheel only while idling in gear at all temps. Today when I got home and after I turned off the engine I heard a noise like water was running. It was coming from the car so I tried to find where the noise was coming from and it's from the fuel tank. I removed the fuel cap and lots of air came out (or sucked in?). I reinstalled the cap and pressure started to build up almost immediately! I have a video, which I'm sharing, so you can see what I'm talking about; I was even able to hear the fuel tank expanding because of the pressure inside, not sure if you can hear it towards the end of the video (when I put the phone under the car). [URL] .....
It also happened today that I was cruising and the engine hit the rev limiter after I stepped on the gas (WOT) to overtake another car. I immediately removed the foot from the pedal and gave it less gas and it acted normal, no slipping from the transmission at any other time. There is one more thing that I'm not sure about it. Every morning, the engine will sputter for 1 or 2 seconds after starting it but it will be fine for the rest of the day. I once tried disconnecting different sensors from the engine and the only one that seemed to make a difference (it didn't sputter) was the TPS.
Things done so far:
- I replaced the EVAP purge solenoid (P0441 was present) back in february.
- Rubber pieces at charcoal canister also replaced, old ones were rotted to the point my hands would look black just by rubbing against the hoses.
- Upper intake manifold was also replaced by me in november last year.
- New NGK spark plugs and OEM spark plug wires last december.
- Cleaned the MAF sensor with MAF cleaner, no dice. Used brake clean, no change. It's a reman Cardone from autozone, which tells us it's 90% sure it's broken.
- New Duralast MAP sensor back in 2010 because a mechanic broke the original.
- 10qts transmission fluid and filter replacement 2 weeks ago.
- Fuel pump was also replaced back in 2009 maybe, can't remember the exact year. The old one would start making some kind of a hissing noise after prolonged driving.
NO DTC'S PRESENT. I once checked Mode $06 data with a mid-level scanner I have (AutoXray EZ-scan 6000) and saw a test had failed, I think it said something about the MAF and EGR. IHaven't connected my fuel pressure gauge tester. Since I can smell it running rich, I didn't think it would be necessary. I'm thinking that there could be a problem with the EVAP system that's causing the excessive pressure in the tank but I'm not sure what that could be. Is there any chance that the pressure is also causing the rich mixture?

My 99 F150 with 200K miles, but running like new, dropped the rusted front gas tank today. I removed it and would like to use the rear tank which is almost new - put in last year.
Is it possible to make it go with only the rear tank? This is only a plow truck (no plates or insurance) just used in my driveway! Top speed for me 4 MPH. hOW TO BE able to get it to run with only rear tank?
Ford F-150 - 1997-2003 :: Rear Fuel Tank Overflow
1996 F-150 5.0... So I bought this truck a couple months ago for a really good price and its my regular vehicle that I use daily. While driving I switched tanks from the front to rear and when i reached my destination i noticed that fuel spilled from the cap, I opened the cap and fuel overflowed. I've read in forums saying that its the Fuel Pressure Regulator or the Fuel Tank Selector Valve . It still drives and runs fine, but I would like to know which part its specifically causing the problem?

My '97 truck has over 315,000 miles on it, original fuel tank, 30.1 gallons, replaced fuel pump maybe a 9 months ago. No gas gauge problems until today. Bought gas this AM and had about 3/4 of a tank. During my drive home (56 miles round trip), noticed the gauge was read about an 1/8. Had monsoon rains today, so I wouldn't have noticed any gas pooling under the truck or a smell if it was suddenly leaking. On the was to fuel up, low fuel light came on. Bought only 5 gals of gas in case tank was leaking and I have to drop the tank. Low fuel light out after restarting the engine but the gauge reads the same, about an eighth? Diagnostic ideas? Won't really be able to examine the tank for leaks until things dry off, probably tomorrow. Diagnostics??

Suppose a puncture hole were to inadvertently appear in the bottom of my gas tank? What would be some good ways to plug the hole? I'm thinking a fine thread stainless steel flat head screw that was screwed into a tapped hole with special glue/sealant and a washer would probably work.
You're probably catching on now... A non electric drill would probably be best to drill into the bottom of a full gas tank but all I have presently are battery powered and 100volt drills.
Ford F-150 - 1997-2003 :: Truck Just Dies And Won't Start At Half To Quarter Tank
2003 F150 5.4l Super Crew. 40k miles. Current service.
About a year ago I ran out of gas on a hill, this is when my strange problem started. Since then I have ran out of gas at least two other times, but both times the tank was between 1/4 and 1/2 on the gauge and only took 8-10 gallons to fill up, so the tank was far from empty! Both times. after I put a gallon or two in, the truck started right up and ran fine. I have gone long trips and ran the tank down to near empty (light on not really empty) and the truck had no problems. But every now and then between 1/4 and 1/2 it just dies and will not start until I put a gallon or two in the tank.
So today, at about a half a tank, the truck dies. I call for the tow service and when the tow truck driver gets there I explain what has been going on. He jumps in the drivers seat and works his magic on the ignition. I don't know exactly what he did but he turned the key to on for like 10 seconds, removed the key, put it back in, turned it to AC.... and so on, obviously ran a clear code or something.... then he turns it over and it fires right up, this is without adding any fuel!
He said that there may have been an air bubble in the line when I ran out of gas before and the computer code needed to be cleared. Is the tow truck guy right? am i in the clear here or do i need to started checking fuel pressure, pumps, filters and so on?

I have a 2000 expy with the 5.4 just turned over 200k. I bought the upper and lower radiator hoses awhile back and finally gotta chance to change them out. I noticed i got the wrong bottom hose so I only swapped out the top hose. I filled it back up with 1.5 gal of distilled water. After I drove it about 60 miles I checked the overflow tank and noticed copper colored flakes in it. Im assuming the previous owner put some stop leak in it but not sure Ive never had any problems as far as overheating or losing coolant. What else could it be? Im going to get the right bottom hose and do a flush. Can I use the bottom hose I have, its got the two extra hoses for the oil cooler? I was just going to connect the two hoses together but not sure if that will cause a problem.

I guess my next move is pull the dash off n fix gauge? It used to be a reliable truck . Now Im not comfortable to let wife drive it . I also pulled the chip to see if that had to do with not starting, also theft light blinks normal. I'm going to get some connector grease n redo all of my wires to c if there's just connection issues.

So today my 97 f150, 2wd 5.4L automatic has started giving me some troubles. The truck has 291k miles on it, i bought it with 260k miles on it. About a week ago the truck overheated due to a busted radiator side tank, it was promptly replaced the next day and i have had no problems with it since, till today. Sometimes when you start it it will stumble alive like its out of gas, give it a sec and it settles down. When you get going, its a little down on power, i know it has 291k miles on it but it pulled hard. Its OK till you get to about 35-40, when it just stops accelerating. I had my foot to the floor and it barely went above 40, if you ease into it slowly it will slowly accelerate till about 45, drop down to 40 and then go like normal.
When i changed the radiator i lost about a cup maybe a cup and a half of transmission fluid, i have gotten time to replace it but i didn't think that small amount of fluid would dramatically change performance, the fluid also looked almost new. The only other things i have done to the truck is some brake work and replace the alternator. I have no knowledge of what the previous over did or did not do. It is not throwing any code, and the OD light/button is broken, i think on newer rangers the OD light would would brink indicating transmissions problems, not sure if its the same on these trucks.
Ford F-150 - 1997-2003 :: 2003 - Running Sluggish Even Replaced Plugs / Cops And Cleaned MAF Sensor?
I've tried everything I can think of and it still runs sluggish.
1. Had dealer change plugs
2. Changed Cop's
3. Cleaned MAF sensor
The 5.4L has slight miss and doesn't respond well at all when trying to pass or going uphills.
