Ford F-150 - 1997-2003 :: 1999 - Ride Rough - Misfire On Cylinder 3?

I'm working on my 99 f-150. I replaced all my spark plugs and coils after I got a misfire on cylinder 3 reading on the scanner. The truck was running ok but two weeks later it started to ride rough again I checked the scanner and got the same reading for a misfire on cylinder 3. Why its giving me the same misfire again? Could my injector cause that misfire? What about the egr valve?

Sonata NF (2006-10) :: Jiggly Ride Between 30 - 50 Mph

Still getting to know my '07 Limited. I got new tires and had it aligned. Between 30-50mph I notice a kind of jiggle in the ride - felt in the seat, not the steering wheel. I noticed it with the old worn tires and thought they were the culprit. It's not bad, just not velvety smooth like it is above 50. Just feels...unsettled, like I'm going over tiny bumps even when the road is smooth. Is that normal for the Sonata suspension?

Ford F-150 - 1997-2003 :: Vibration / Grinding Sound Coming From Truck When Moving Slowly And Making Turns

I have a 2003 Ford F150 with a 5.4V8 Triton 4X4. The truck is about to roll over 200K here soon. I am feeling/hearing a vibration/grinding sound coming from the truck when I am moving slowly and making turns, either left or right turns. Seems to happen more so on left hand turns. I have changed all power train fluids and filter, and still does it. I do not feel or notice the vibration/grinding when I am going straight or at highway speeds. It is only when I am moving from a stop and making turns. How to diagnose, find out, repair, fix this issue?

Ford Super Duty (1999-2016) :: 2003 F250 - Stiff / Rough Ride When Empty

On a 2003 5.4 f-250 XLT 4 door, long bed

Running 285 tires, none lifted, factory lifted for snow plowing? Did have a plow mount when purchased used.

Had the truck over a year now & love it. My only real dislike is the stiff/ rough ride when empty, which is 80-90% of the time for me.

I know my truck & year have leaf springs with shock dampeners on the front, vs the coil spring and shock dampeners that came in the later years for a much improved ride. Also my struts are "Rough Country" which from what I understand are cheaper shocks. Had a 04 Tacoma I replaced with Bilstein 5100 shocks after leveling it & it was an amazing difference. So that's my only real comparison in shocks. I've read of guys replacing their entire front end for the coils & springs. Not interested in going that deep into it for a better ride. If that's my only option, all be happy with the ride as is.

What are my options if any? Better shocks/struts? Other than my rough country that are on the truck? Purchased used a year back & never felt the "stock struts".

I did find Bilstein 5160' s for my model truck. Link : [URL] .....

Ford Super Duty (1999-2016) :: Replacing Shocks - Rough Ride?

It is about time to replace the shocks on my truck but I am going back and forth between shocks... I have 37s and the ride is rough to say the least I am looking for something to make it feel like I am not riding around on a jack hammer every time I hit a rock.

Dual set up in the front and single in the back and I have steering stabilizers installed.

Ford Super Duty (1999-2016) :: 2008 F250 - Very Rough Ride

My 2008 F250 Super Duty is riding very, very rough. I put in new heavy duty Bilstien shocks 2 or 3 years ago, and I would think they would last longer than this.

Are they any other causes I can look at to see what is causing this truck to ride rough?

Ford Super Duty (1999-2016) :: 2012 F350 4x4 Diesel - Rough Ride

I have a 2012 Ford F350 SRW 4x4 Diesel. Love the truck and has been great. I have 20" Tires and the ride on this truck is really rough. I know its now a Cadillac but to change tires or suspension components to get a smoother ride. I was thinking about going to 18" rims and getting a big all terrain tire. Maybe taking a leaf spring off in the rear. Going to air suspension. Different tires maybe. I dont need the load rating since i sold my fifth wheel.

Ford Super Duty (1999-2016) :: 2015 F250 - Rough Ride / TPMS Light Comes On

Im an outside sales rep and I drove 85k miles last year in a F-150. The time came where I needed a new company truck and now I'm in a 2015 F-250 2wd 6.2l lariat. I love the truck but my back is killing me. I've only had it a little over 3 weeks but it has over 6k miles on it. The majority of the time my bed is unloaded but there has been a few times my 1/2 ton was overloaded so i stepped up to a 3/4 ton. Ive tried lowering my tire pressure but the TPMS light comes on. I also bought sand bags to leave in the back of my truck to add weight to it when not loaded. Im about to pull the trigger on bilstein 5100s but was wondering of there is anything else I could do make the truck ride a little smoother.

Ford Super Duty (1999-2016) :: 2005 F350 - Rough Ride / Severe Shaking

Having a somewhat scary problem.....my truck is already a rough ride due to the fabtech lift and the 37's and you get a lot of feedback through the steering wheel. Its a rough ride down the highway but where it gets scary is at lower than highway speeds like 35-45 range. I can hit a bump and it will send the trucl into this insane cavitation that will literally shale the fillings out of your teeth. I cannot tell if it is in the drive wheels or the front wheels. The best way I can describe it is that its like trying to push a buggy in wal mart with a bad caster wheel on it. It feels like you are about to have a wheel fall off or that its broken off a tie rod or something. Then you simply slow down to a stop and you can drive right on like nothing was wrong. The vibration or shaking does not slow down with the speed. I cannot find anything obvious broken or damaged but this thing is getting dangerous to drive.

05 F350 DRW Fabtech 6 inch lift and 37's. 114k miles.

Ford F-150 - 1997-2003 :: V6 Slowly Overheating In Hot Weather

I have an 1997 F150/4.2 V6/220,000 miles/4x2. During hot weather (over 90F) the engine slowly overheats. While driving on the interstate (from Indy to Fort Wayne), the coolant temperature shows normal on the gauge. Slowly the temperature gauge creeps up to close to the red area. I am running the A/C.

When I switch the heater on and the heater fan at max, the temperature gauge drops pretty quickly to a normal range. I switch off the heater and the A/C back on, then it takes 30 minutes for the temperature gauge to start rising again.

When I open the hood when the gauge shows close to the red area, the upper coolant hose has a lot of pressure (can not squeeze it), which would mean that the thermostat is open and the water pump is working. Also the fan is running fast.

The coolant was changed out a few weeks ago and the coolant level is at normal level when the engine is cold. At lower ambient temperatures, there is no overheating. I am puzzled what the problem can be. I am thinking of a restricted coolant flow.

Ford F-150 - 1997-2003 :: 1999 - Won't Start If So Then Rough - Fuel Pump?

Drove for 25 miles. Park, try to restart to park truck at other place. Truck start but very rough. Did drive for 20 yards and truck stop. Try to restart no way. I think I do not hear fuel pump when I turn key and gas pedal fill completely empty, no any force to move it. Should I assume fuel pump or should check some sensors first? I have P0420 for a few weeks, not source of this problem. Drove truck before with P0420 for years. No other code. Do we have PATS in keys? My truck is f250 99 LD. My pickup have PATS. How to check it?

Ford F-150 - 1997-2003 :: 1999 4.2L - Hot Start Rough Idle / Surges Sometimes

I am new to FTE and have a question about my 99 4.2l. After it warms up, i can shut it off and about 30 mins later try to start it again and it will idle very rough and sometimes stall. I also noticed that it surges sometimes with just off idle throttle when its cold. I am not getting any codes thrown, here's what I've done so far: cleaned the maf and throttle body, and it didnt work at all. I did convert my cht over to ect by using the plugged coolant outlet on the lower right side of the intake manifold and extending the connector wires which actually solved the problem a little bit but it still does it from time to time.

More info about the cht to ect conversion, but after reading that ford did away with them in later models i wanted to do the same while at the same time making it so much easier to swap it out if ever needed. No more getting under the truck. And where im at cht's are kind of hard to come by without having to order them Anyway, it worked flawlessly! I only had to extend the wires by about 8", wrapped them and ran it along side the injectors for a clean factory look. Ill try to post pics soon...

Ford F-150 - 1997-2003 :: 1999 5.4L - Idle / Running Rough Occasionally

I purchased a 1999 F-150 Lariat 4x4 automatic transmission about a year ago. When I did, the previous owner told me about an idle issue that he has occasionally. He said that the issue was with the IAC. He claimed that he had replaced it several times but "it was hard to get a good aftermarket IAC that actually works". He said he tried several, but it never fixed the issue. That sounds like he wasn't replacing the defective part to me, but I don't know. This is my first truck to ever purchase.

Fast forward a bit (about a year), and I have had intermittent issues with idle and running rough since I bought the truck. I don't drive the truck that often, but they are becoming more common, so I want to get things fixed now.

Issues:

1. When running at idle, especially in park, the idle seems to fluctuate and never stay consistent. The idle drops as soon as I put it into drive, and the truck jerks a bit when going into drive because the idle was too high in park. It has never died while at idle, however.

2. When driving, especially up a slight or moderate hill, the power seems low and the truck starts to ping and jerk. The only way I can avoid the jerking is to stomp on the accelerator and go into a lower gear. And even when doing that, I still can notice an ever so slight jerk.

3. This past week, it was rough for an entire 40 mile journey on the interstate. Slight ping the entire ride home. When I pulled into the driveway, it was jerking until I turned it off. I haven't tried to drive it sense.

Potential issues:

1. IAC - maybe the previous owner was right. Maybe I should replace it again, or clean it with some carb cleaner.

2. Cam Phasers - I saw some posts about this on the forum.

3. EGR valve - Also saw some posts about this.

4. Maybe even the transmission? It doesn't seem to have an issue going into or out of gear, though.

Ford F-150 - 1997-2003 :: 1998 - Can A Heater Core Slowly Go Bad

I have 1998 F-150 and the heater core was replaced 18 months ago. All was going well until about 2 weeks ago I noticed under heavy acceleration I would smell antifreeze. The smell would clear up and would not re appear for a day or so. Finally the other day when it was 8 outside I got in the truck and got about 5 miles from the house started up a hill and it was like a fog machine was mounted behind my dash the windows fogged up almost immediately so I figured great the core went bad again. Now the temperature has warmed up the last couple of days and there is nothing no fog in the cab the heater works fine just an occasional slight smell of antifreeze. Before I go through the trouble of tearing out the dash is there anything I should check I already checked the connections on the firewall and they were fine.

Ford F-150 - 1997-2003 :: 1999 4X4 - Intermittent Misfire / Runs Rough For About A Minute

I have a 99 F150 Lariat 4x4 with a 5.4, 150,000 mile on it. About 2 weeks ago I blew spark plug out on #2, and a friend who said he has heli-coiled a bunch of these tried to do mine and ruined the head. Anyway, I called a local engine shop and got another PI head, only I used my cam in it. Torqued it as per the book, etc... Mind you that the engine ran perfect before all this.

Got it back together with all new plugs, new exhaust manifold, and 2 new COP's. When I start it-it runs rough for about a min, then straightens back out to run perfect again, and after a few seconds you can hear a solenoid click, then it goes back to missing again. This goes on and on... I went through all the vacuum lines and checked them, checked the egr valve, put on a new IAC, new PVC, cleaned the MAF, and checked everything else with a DVM.

I took it out and drove it.... Runs good for a minute, then it goes back to missing, then back to smooth again. This just keeps going on and on. I noticed when I hear that click, it sounds like a mad rush of air being sucked in, but I cannot locate it. I ordered a new set of COP's to try next. I can understand if it just plain missed all the time, but this it intermittent. Also, the only code I can get is a too lean on bank 1, so I replaced the 90's and the pvc valve. Now no codes but still in and out of missing. It ran perfect before the new head.

Ford F-150 - 1997-2003 :: Parasitic Draw / Battery Is Slowly Discharging

With the hood open and the hood light bulb pulled out, measured the parasitic draw on their truck? I checked mine because it appears my battery is slowly discharging if the truck sits 3 or 4 days. I got 0.24 amps which seems in line with running the clock memory and the computer. I have a feeling the battery is shot even though it is only 3 years old. When I bought the truck it had a ton of yellow fuzz on the terminals. That is cleaned up and with it running I get about 14.35 volts at idle so it is charging. 0.24 draw??
