Ford F-150 - 1997-2003 :: Truck Refuses To Move Off Of 12 Mpg / Terrible Gas Mileage
Why I am getting such terrible gas mileage? The truck refuses to move off of 12 mpg. I made a 500 mile trip half of it at 70 mph running 2100 rpm. And when I filled up I calculated out 11.3 mpg. After that fill up hopped on the interstate and was running around 85 @ 2600 rpm expecting my mileage to drop even lower. Then i was on two lane hwy again constantly passing people and it only dropped to 11.1 mpg. Now no matter how easy I drive or how hard I drive it will not move over 12 mpg. Whether the tank is 100% hwy or 50/50. Its a 5 spd manual 4x4 with no modifications running the 4.6 v8. I just swapped air filters to a K&N and still no change.

I have a 2001 f-150 the brakes are sticking and I get a bad shake which seems to come from the front and rear of the vehicle. It doesn't do it all the time but when it does it slowly gets worse. I have replaced 3 of the 4 calipers and will be replacing the forth, but not much is changing.

1997 F150... Truck has slowly started getting worse and worse performance. About 3 weeks ago the truck started rattling from the exhaust, Towing my trailer the other day, the truck had NO power, I thought it was the plugs, so I replaced them.
Now the rattle is worse (no lose heat shields). I am blowing the little tubes off the drivers side exhaust manifold, the ones that go to the DPFE sensor.
Did I mention, that the truck has no power, sluggish, now I am dumping hot exhaust fumes into the engine compartment. Still got the rattle underneath.
I think the cat is plugged up on the drivers side. (which probably explains all my symptoms)
Any other reason for the rattle literally coming from the drivers side cat and the little tubes being blown off?
Ford F-150 - 1997-2003 :: Truck Only Starts In Neutral
I started having trouble with the truck only starting in neutral and it was a trick to get it to start even then. I bought a new range sensor, bolted her up (with alignment marks in neutral) and she's still doing the same thing.

I went to walmart and let the engine run for a while and shut it off. It would not start until it cools off. Now that its cool it starts fine. It just started doing it. Come to think of it i did get some gas in it.

I have a 2000 f150 4x2 5.4 168k... Check engine came on,started shaking, weather was really cold. RPM would be a little high then low then back up. Especially when I turned on heater. Felt like truck would die but never does nor does it have issue starting.
So far, I have replaced two oxygen sensors inside engine,all coils, spark plugs, fuel filter, had injectors cleaned, intake cleaned. Truck runs better but, light came on a day later again. I can feel the tiniest of shaking going on and, cold mornings still make RPMS a little unstable. I was driving truck on highway at about 60 mph when a slight tug was felt and Truck check engine came on. I feel truck heavy, once it warms up completely, a little lighter.
Codes came up at auto zone as P1151
But I'm running out of options and frankly, money to fix this truck.
Checked the MAF and looked okay.
I'm with minimal skills.
Ford F-150 - 1997-2003 :: Truck Starts And Then Immediately Stalls / Idles About 3 - 4k RPMs
If I don't keep in the throttle immediately after start up it will stall a lot of the time. It doesn't do this every time or if it sits for a while but if I drive it and then stop off at a store or something and then go to start it back up it gives me this problem. I notice it idles about 3-4k RPM's when I stop at a light or something too.

I have a 2002 F-150 and started making terrible noise when turned on heat/ac. The fan cage was full of acorns and pieces of insulation in it. How can the squirrels get in there? I have looked and see no entrance, maybe just don't know where to look.

If i punch the gas it flies right through the gears with little shaking. Ive heard its the u joints, I've heard its the tranny. I don't know what to do or try to figure it out.

I bought a 1997 f150 with 160l miles on it. It is a 4x4 with the 5.4 v automatic. While I'm drive and in 4th and 5th gear, the tranny shakes the whole truck and then shifts hard! I check the fluid and it's still good and red but looks like there is to much. I'm planning on removing some and adding some lucus additive in it. What could cause this???
View 8 RepliesFord F-150 - 1997-2003 :: 1998 - Rough Running Truck When Accelerating
I have a 1998 F150 4.6 2wd regular cab with 255,000 miles on it. Lately it has had some problems. The first is that it will run really rough when under a load, meaning when I step on the gas. It runs smooth at idle and at cruise but when I step on the accelerator it bogs way down and almost shuts off. I have changed the spark plugs, spark plug wires, coil packs and fuel filter. Now I'm thinking maybe fuel pump?
The other issue is that when the truck is having to work a little harder (i.e. pulling a trailer or running in the summer with the AC on) it will start to run hot. I have changed the thermostat, flushed the coolant, cleaned out the radiator, etc. and it still does it. Could both of my issues be related to a fuel problem??
Ford F-150 - 1997-2003 :: Truck Suddenly Started Running Rough / Too Many DTCs All At Once
I have a 2001 F150 4.6L auto. This truck suddenly started running rough. Cleared all codes and re-scanned after starting truck. The codes are as follows; P0135, P0155, P0443, P0740, P0743, P0758, P1451, P1460, P1747, and P1760.
My question is; is it normal to have this many DTCs come up at once? Could my PCM be faulty causing this problem? Can you swap a pcm from the same year truck with the same options without reprogramming?

Ford F-150 - 1997-2003 :: Truck Idles Very Rough - High Rpms Fine - Reason?
So my "farm truck" is idling very rough, to the point that sometimes that it stalls out. At high idle it runs fine but when its at a idle its very rough. Its been running fine until probably a month ago or so and its just getting worse. What it could be? I am thinking it might be that something is dirty but i just dont know where to start with figuring out what the problem is.

I have been having some issues with my 97 ford f150 4.6 liter, started out running rough, then hydrolocked with no serious damage, blown intake manifold gasket, fixed that, alternator over charging do to bad voltage regulator, fixed that. and airbag code 52, still working on that, as well as failure to connect when trying to do diagnostic scan. now I am wondering if the engine diagnostic is still even working. still running good just a very slight vibration when warms up. I am not getting any code. or my check engine light is not showing any codes. What I want to do is force a code. What would be the safest way to force a code or force engine light to give a code?
View 6 RepliesFord F-150 - 1997-2003 :: 1999 V8 Will Not Start / Truck Started Idling Very Rough And Died
1999 Ford F-150 V8 5.4L... The other day I was attempting to fix my 4wd. I discovered that the vacuum tube by the 4wd solenoid had become disconnected. I reconnected it and in an effort to see if my fix was successful, I drove my truck up one of the canyons nearby. I got to an area full of loose rock and popped my truck into 4wd. As soon as I began to drive, the truck started idling very rough and died. I attempted to restart it for the next few minutes unsuccessfully. I got it started once and it continued to idle rough for a few seconds and died. I have not been able to start it since. It turns over but will not crank. It is not throwing any error codes. What I have checked so far:
Spark plugs are working.
When turning the ignition into the ON position, I am able to hear the fuel pump working.
I have not seen any cracks in the vacuum hose.
All the fuses are still okay.
What the culprit may be?
Ford F-150 - 1997-2003 :: 2002 Truck Started To Idle Very Rough - Codes PO308 And PO316
My truck started to idle very rough. I pulled the codes and I got po308 and po316. First I changed plug #8, the electrode was nearly gone. I have never seen a plug in worse shape. Replaced that plug and fired it up, it still idled rough and threw the same codes. Next I moved the #8 coil pack to the #1 location and vice-versa, still the rough idle and same codes. Then I moved the #8 injector to the #1 location same results. Finally I tested compression in the #8 cylinder and it read 32psi ( not good) everything else read 150 to 160 psi. Squirted some oil into #8 and no difference in compression.The truck is a 2002 with 184,000 miles, it burns a quart of oil every couple weeks but still is in perfect shape. Should I bite the bullet and invest in a remanufactured engine for 2500.00? I put one in my 97 f 150 a few years ago with no problems.
