Ford F-150 - 1997-2003 :: Sudden Misfire - Puff Of Grey Smoke Coming From Throttle Body
Sep 14, 2015
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.

I have a 2010 Ram 1500 4x4 quad cab, 4.7L, 25,000 miles. When it sits for a few days, it will emit a puff of grey smoke on starting. It won't do it the rest of the day, and even the next day, but after about 3 days, it will do it. The truck sits nose up on a sloping driveway with a slope of about 1'/20' when parked. Truck runs great otherwise. Dealer says that this is normal for that engine, but I doubt it, as I don't see it discussed anywhere. Is the dealer right or just trying to get me past the new car warranty?

Was driving down the highway and got a smell in the car, thought it might be diesal from the truck in front. When I got off and came to a stop, car would not accelerate at first, it hesitated and a puff of grey smoke came out of the back. Stopped for a few minutes everything seemed fine then the check engine light came on. I have managed to get it up with just a couple of rattles, but the check engine light is still on. Have I killed the car by driving it home. The light was not flashing it was completely on.

I have a 03 6.0. I just had all the injectors changed a new fuel pump, spring in the regulator and fuel filters ouch. The truck runs great but I get a puff of black smoke if I get on the throttle going down the road it seem to clear up as soon as the turbo spools up. I that ok or do I need to take it back to the dealer?

I didn't notice anything until I was towing yesterday and tried to pass a car to get onto the offramp.
Anyway, I went to floor it so I could get around and, in my mirror, I could see a decent bit of grey smoke coming out. What could it be?
It doesn't smoke at all on startup and runs smooth right away.

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.

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.

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 ...

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.

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.

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.

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.

I have a 91 camry that failed the CA smog test because it lets out a puff of smoke when you floor and release the throttle. Could it be anything other than the rings?

I was driving down the road and the car was driving great. all of the sudden I heard a clunk and the car lost power and started shuddering. I made it home and cut the car off. When I start it now, the car runs rough and stalls out. I can't get it to a place to check the codes so I am trying to self diagnose. I was thinking it might be the MAF so I took it out and cleaned it well. there is still no change in the way the car runs. it seems like the fuel isn't getting to the engine as I put my foot on the gas pedal it stalls out. I'm not too excited about buying a throttle body if it's the MAF. It could possibly be something else.

I have a 12 F150 with the 5.0L. it has 27000 miles on the clock. Noticed twice a small puff of white smoke coming out of the exhaust and decided to check the oil level and it was a quart low. The last oil change was done at 23000 miles and used Full Synthetic Pennzoil and a K&N filter. Called the local dealership I purchased at and they told me NOT to use full synthetic and should only be using Motorcraft semi synthetic with a Motorcraft filter. I know the dealerships will only endorse and advice Motorcraft products but what does everyone else use and think. In the meantime I added a quart of oil and all is fine.

I replaced the rings on all 8 injectors put in 8 new glow plugs and a relay. My truck is still putting out grey/ white smoke at start up. It goes away after about a minutes. Truck runs a little rough a first then smooths out. I know some smoke after doing a job like this is to be expected but I was thinking I t would go away by now. I've been running through my head what I might of done wrong but I can't think of anything.
Does it just need all new injectors and not just rings ?

Picked up my 5th wheel this afternoon from being raised 3". Dropped over the 10 percent grade down the hill to normal driving. Had the trailer brake controller to boost #2 (Prodigy controller). Had to brake pretty continuously, (tried to stay off it a bit, but is is about 10 grade for about 3/4 mile. Put the auto trans in D2 to get brakes come to the red light at the bottom. Noticed a puff of smoke at the front. Driver side, didn't notice passenger side.
New pads and new slotted rotors new maybe 1,500 miles ago. Not liking that action, but need thoughts. Want to put a thousand or 2 miles towing this summer and accompanying mountainous terrain and back.

My beloved excursion is 300 miles away from me in a no start condition. Vehicle has 270K miles. Very well cared for. No issues to date since purchase 5 years ago. Went to back up and the vehicle starting Caming like it had a big cam in it. went from reverse to drive and problem went away. Drove vehicle for 2 more weeks without issue. Then all of a sudden it dies. Restart driver on down the road 1/4 mile, dies again. Restart, make 45 mile drive home vehicle is low on power will hardly pull a grade but I got to my friends house. Went to start vehicle next day and no start. Puff white smoke while trying to start. It hits every once in awhile but wont run.
The vehicle is throwing NO CODES other than an open glow plug on 1&8 which it has for sometime now. I have changed, fuel filter, fuel pump, CPS(genuine ford), IPR and IPS. No real changes still wont start. I disconnected the IPS and it started but it sounded like it was only running on a couple of cylinders. It would not accept throttle. The local Forddealer does not have a Ford diesel tech. Ive called a couple of diesel shops and I hear could be a bad HPOP, or bad ECM or a bad IDM but without seeing it. I am at my wits end with this thing. I am an electronic engineer by background. So I have a good sense of the process. I have checked all fuses, relays, etc. I will say I did have one issue with it a year ago where the UVC problem popped up but the dealer fixed it and it has been fine ever since.
