Ford F-150 - 1997-2003 :: Surging When Only At A Very Min Throttle
I have been fighting this surging issue for a while. I noticed when it starts to surge i could turn off the a/c and it would quit. It only surges when i am only at a very min throttle. Does this make sense? What can I do to fix it?

Ford F-150 - 1997-2003 :: Throttle Body Cleaning
I need to clean my throttle body on my '97 F-150 and it has a label saying not to clean directly. Is it still safe to use TB cleaner and to go ahead and clean it? It needs done but how would I go about it.

I have a 1997 f150 with the 4.6l triton that just started to make a squealing noise. I have replaced a couple of pulleys that were bad but that did not get rid of the problem. It only makes the noise when I give it some gas and it is coming from around the fan clutch area.

The Throttle Body on my 2001, 4.6 L is making a strange whirring noise, when you puy your hand on the intake pipe, you can feel a slight vibration. The Truck idles and runs okay, with no codes. Giving it a little gas and the noise goes away. The last thing I did was clean the IAC with Gum Out Carb cleaner, the second or third time I've done this over many years, with no problems. I'm a little perplexed at the cause.

My 01 Super Crew 5.4l is missing at light throttle. Cruise control on flat hwy, no miss, slight incline, starts missing. Put my foot into it and either it stops missing or it covers it up where I don't notice it. No codes set at this point. It's got about 135k on it and for all I know it may have had the original plugs in it so I figured I'd change them. Changed the plugs, still misses. Shortly a code set, something about the EGR sensor (it's got another name but I forget what it is at 1:30am). I found I had broken a hose while changing plugs, fixed it, no more code, still misses.
When I sent my GF up to get the non-existent codes checked the parts guy sold her some Lucas fuel system cleaner. I'm figuring a COP going out but the cleaner pretty much completely fixed the miss, till that tank of gas was gone. Few tanks later and it's back again as bad as ever. I bought some seafoam as I've had good luck with that in the past. It almost completely fixes the miss but I get a rare 'bump'. What do I need to look at next? Can it be the fuel filter? I'd think no because I'd figure it'd be even worse at greater throttle opening. Injector? How do I check them?
Ford F-150 - 1997-2003 :: Hesitation As The Throttle Is Pressed During Driving
2003 Ford F150 XLT - Truck hesitates (or bucks) as the throttle is pressed. Not from a stop though. It starts / runs fine, but no matter how how fast, what gear, hot or cold, it feels like the fuel cuts out for 1/2 second. Also it is not a specific point in the throttle motion. It does it when it is halfway, 3/4 or fully depressed, but is not consistent. It does happen more frequently now than two weeks ago. I am not getting a check engine light.

Ford F-150 - 1997-2003 :: 2002 - Throttle Feathering While Cruising
I just had an exhaust manifold replaced on my F-150. It has the small 8 cyl.. While the manifold was leaking, the truck of course ran like crap.....spitting, sputtering, barfing, etc.
Now that the manifold work has been done, the truck runs pretty well, except for some intermittent increase in throttle (not by me) when cruising at highway speeds. This is comparable to the "feathering" of the throttle that you would do when checking for engine noises.
Hard to explain without feeling dopey, but kind of a mild ruuum, ruuum, ruuum out of nowhere when I'm cruising along. I drive a 5 hr. trip every weekend, and it will do this about every 10-20 minutes.
Ford F-150 - 1997-2003 :: Started As EGR / Throttle Body Clean
I'm usually over in the EX forum but today was working on my brothers 1998 F150 - V8 4.6L. Had the EGR code P0401 and due to FTE I found the problem took the throttle body off and found it was definitely plugged. One of the bolts was really loose and came off way to easily. Didn't realize until cleaning why... Now I drilled 8 studs out of my aluminum EX heads but this one has me pondering how I'm going to clamp this thing down and center a bit..
1st pic - ports WOW - guessing this was the problem ...
2nd pic - bigger issue ...
3rd pic - the ports cleaned up ...
Ford F-150 - 1997-2003 :: Switches To Defrost When Step On Throttle
When I have my a/c on, every time I step on the throttle it changes where the air comes out of the vents . Under normal power the air blows out the front vents, step on the throttle and it switches to defrost , let back off and it goes back to normal.?????

I have a throttle body noise that sounds like a warble,It is sporadic and I think it should not be their. But I have heard some other f-150s make the same noise. Is it normal or is something not right.

For example. If you are going 30 mph the engine surges. It surges when the throttle is in the same tps location.

I busted the cable end by not removing it properly. My question is what is the proper method of remove the cable from the throttle body? Are the cable ends replaceable? If so who has them as a google search didn't find any? I've tried to find written information but haven't any luck. bl2009

I accidentally broke the control lever where the cruize control attaches. I've looked all over but I can't find the lever. Where I could buy just the lever? New throttle body is more than I want to spend.
View 1 RepliesFord F-150 - 1997-2003 :: Knocking And Vibrating - Gas / Throttle Pedal Noise
2001 F-150 4.2L automatic, 189k mikes. Gas pedal would do weird knocking/vibrating. It would do it at idle & under acceleration. Gas pedal would knock & sometimes slightly move or kick back at you. Felt like someone was lightly hitting it with a small hammer. Well there is not much to the gas pedal assembly; pedal, throttle cable & mounting bolts/plate. Looking under hood, a bracket from drivers side of motor was pushing back against firewall, which was pushing into gas pedal mounting bolts. I grabbed the bracket & it came off motor. Nothing else attached to bracket. Looks like it rusted off and was pinned between motor & firewall. Well, this fixed the gas pedal problems. But now i wonder what the bracket is & whats it suppose to hold??

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 F-150 - 1997-2003 :: Broken Throttle Body Accelerator Cable Connector
So, instead of pushing the throttle cable back and then off, I tried to pop it off and broke the little tab. I've been trying to look for a replacement, but all I'm coming up with is an entire throttle body. Not too bad, but would still like to fix it for much cheaper. It's a 2002 F150 with a 5.4L.

2001 F150 5.4 4x4 148K... I recently replaced the intake manifold on this truck and when the engine revs it wants to continue at high RPMs for about 10 seconds after letting off the throttle. When driving, it almost wants to go faster and the gas mileage is really bad. Had some codes come up and took it to AZO and had them checked. P0171 & P0174. Guess I need to do some testing on the MAF and injectors.
View 2 RepliesFord F-150 - 1997-2003 :: Sudden Misfire - Puff Of Grey Smoke Coming From Throttle Body
Obviously its not a good thing, but this seems a little severe for a truck that hasnt had any issues prior. The truck is a 1998 F150 4.6 and was running just fine until POP!! A puff of grey smoke coming from the throttle body and followed by (obviously) a rough idle. So basically, I know that any metal fragments were directly sucked into the intake and based on the size of the chipped area (roughly 1.5cm). I am wondering what type of internal damage this would (or already has) caused.
