Ford 7.3L Power Stroke (1999-2003) :: Loping Really Loud At Idle
I found an interesting thing, when I start the truck right away without waiting for the glow plug light to completely cycle (Engine at operating temp) the engine will lope REALLY bad. Now, when I wait for the glow plug light to finish and then start the engine, it runs as normal. I checked and cleaned the PCM pins for the chip and everything is good. Ghosts & gremlins.

e99 with 291K on 7.3L
Idle sound horrible. Sounds like a really loud dieseling or I dumped ball bearings in the topside of the engine. When I start to give it a little pedal, the sound drops to normal. No power issue I can tell.
This just started this morning. It happened when cold and then again when hot as well. While driving, and at temp, when I let off the fuel to coast or stopped at a light, the loud idle would cycle on/ off like someone was throwing a switch. When I got home and popped the hood, I could not tell where the sound was coming from.
Ford F-150 - 1997-2003 :: 1999 Lariat Not Starting / Loud Click When Turn The Key
I have a 1999 F150 Lariat 5.4 that's been sitting for a few weeks waiting for a new MAF. Finally got a MAF from a junkyard (out of an 01 Expedition) and installed it.
Turned the key, cranks once, then I hear a loud click and then just continuous clicking. I did some research and people are saying this is just the starter solenoid and that the battery may be dead. I charged the battery a couple hours and waited until it showed 11.some volts, tried to start it again, didn't even turn over, just clicking. I also noticed the theft light blinking rapidly, but if it were the PATS acting up, wouldn't the motor at least turnover?
So I went back to charging the battery. Went out a couple hours later (at night), and when I opened the door, none of the lights came on. Then I hear a click, the lights come on, followed by another click, and the lights went off. This happens each time I open and close the door. So did I potentially pop a fuse? Or is my battery just fried? Would replacing the MAF with the newer one out of the expedition cause any weird issue? I doubt it, but anything is possible at this point I guess.
Ford 7.3L Power Stroke (1999-2003) :: HPOP ORings Replaced - Injectors Loud After Start Up At Idle
Just replaced all hpop orings. Injectors loud after start up at idle. Guessing air in lines. How long do I need to drive before all air out of lines and everything back to normal?

I have a 1977 f250 460 with c6. As far as I now everything is stock on the motor. The carb is a motorcraft but I cant see what model it is, there is a ID tag that I need to get the numbers off of so I can see what I have.
I don't know much about carbs so I'm trying to learn as I go, but what has me wondering about the secondaries is going up inclines. We have a canyon that is a decent grade and long, I was towing a empty flatbed trailer and with my foot all the way down could never get it above 40 mph it just felt like that was it. I have been out playing with no trailer and it feels like I can get them to open up when it down shifts, but cruising along at 55 and stomp it nothing.
I am worried about pulling our camp trailer with it and that is the main reason I got the truck with a 460. What to check?
Ford F-150 - 1997-2003 :: 1999 5.4L - Low Idle With No Codes
The truck ran fine this morning and this afternoon I had trouble with the truck running at idle.
The idle is at about 450RPM in park. Runs smooth with no miss but if you bring the idle up and then let off quickly it stalls. Can stall while trying to idle at warm up also. Sometimes it will stall at a light but I think it is related to taking my foot off the pedal quickly.
There is no check engine light on and there are no codes. I have 138K on the engine now. Both air & fuel filter were replaced about a month ago as well as the PCV valve.

Ford F-150 - 1997-2003 :: 1999 - Stalls At Idle - Won't Start?
My dad has passed his 99 f 150 with 130,000 miles to me. It is a 2 wheel drive, extended cab automatic equipped with the 4.6. Recently, the blend door failed and as a temporary measure I installed a ball valve in the heater core supply hose. The ac now blows ice cold.
On two occasions since the installation of the ball valve, the truck has stalled at idle when in park and would not start, although it turned over fine, until 30 to 45 minutes elapsed. On both occasions it was a hot day. The check engine light is not on and no codes are stored.
Ford Super Duty (1999-2016) :: 2003 - Muffler Delete On Stock Exhaust Sound?
How will a muffler delete on stock exhaust sound? I don't want to remove the cat because I don't want it to be too loud. I want it to sound good but not too much whistle (considering my truck is a 2003 the whistle would be very loud) Should I just to a delete pipe on the stock exhaust, or do a cat-back 4 inch straight pipe? what will sound better? Also doing the cat back exhaust will cost a lot more.. but is it worth it? What I should do.

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 6.0L Power Stroke Diesel :: MBRP Muffler Is Too Loud - Droning At Certain RPM
I know some of you can't get your truck loud enough and like to scare children and want everyone to look, but I like comfort and quiet. I'd prefer the stock exhaust and I may find one if I can't get mine quieted down but first I'd like to see if I can. The 4" MBRP exhaust was on the truck when I bought it. The thing was straight piped and I added the 30" muffler. Worked immensely but it's still too loud in the cab and there's droning at certain rpm.
Not a big deal on short drives but we use the truck for hauling and towing on long trips and that's when it becomes annoying. It looks like there's enough room for another muffler to easily fit (CC SB). Or I've thought about removing the MBRP muffler completely and putting on one of those crazy long Donaldson mufflers. Think a 2nd muffler would do much at all? Or get one long muffler?
Ford F-150 - 1997-2003 :: 1999 XLT - Cylinder 4 Misfire / Shaking When Accelerate Or Idle
Ford F150 1999 5.4 XLT... I've had this truck since may 2013 from the 2nd owner who only drove it
occasionally to make sure it ran. For the last 5 weeks there have been two occasions where my service engine light appeared...once on 12/28/15 and again today. Both read cylinder 4 misfire. Upon searching this piece which I'm assuming is the boot that covers or houses the spark plug is very unsecure and causes a shaking feeling as I accelerate or idle. Being so far back I can't reach it with extensions on a ratchet and barely fit my hand back there. Having to consider taking it into a shop for further analysis and repair but I'm trying to save as much money as possible as I am in between jobs since mid January. I have a picture attached...
Ford F-150 - 1997-2003 :: 1999 - High Idle After Cleaning Throttle Body
High mileage 1999 4.6 4wd 5 spd: Needed to replace the rear ABS sensor and decided to clean the throttle body too while the battery was unplugged. Cleaned it around the butterfly and not much else. Truck idled at 750 BEFORE cleaning the TB. Now it fluctuates between 820 and 950 rpms. Also tends to stay at a higher rpm after pushing in the clutch and taking it out of gear.
Did a thorough check for vacuum leaks, nothing. After research, I cleaned the IAC and re installed (battery was disconnected then too). No improvement. Unplugged the IAC while running- ZERO change in idle. Installed new IAC, no change whatsoever. Unplugged NEW IAC, no change whatsoever. Is there an issue with the PCM needing time to fully re learn? Am I missing something.
Ford Exhaust System :: Loud Pop While Cruising At 60 Mph - Muffler Blowout And Rough Engine
Yesterday, I heard a loud "pop" while cruising at 60mph. Pull into a rest stop and and discovered a hole in the muffler. The engine now idled roughly, but seem to smooth out about 2000 rpm.
Question for the experts: can the loss of a muffler cause the engine to run rough? It's a 460cid in a '77 F350.
Ford F-150 - 1997-2003 :: 1999 - Idle Hangs When Push The Clutch In While Coming To A Stop
I have a 1999 f-150 4x4 4.6 5spd manual 180,000 miles on the clock. My question is, when coming to a stop i push the clutch in an the idle hangs at about twice what it should be until i come to a complete stop then it drops to normal. It's not like somethings sticking cause it will stay at the high idle as long as were rolling but as soon as the wheels stop turning it drops down.

I have received the error code P1506 on my 1999 F150 which is I believe an idle air control overspeed error. It seems to run a little rough at idle but not too bad. At the advice of my Haynes repair manual and the advice of a friend I have already replaced the IAC valve and the PCV valve on the engine and cleared the code, only for it to come back again after 50K miles. I am not sure where to go next with the diagnosis/fix.
