Ford F-150 - 1997-2003 :: Excessive White Smoke Coming From Exhaust And Rough Idle
I'm losing coolant have, excessive white smoke coming from the exhaust, and rough idle. Doesn't over heat or even try to overheat. The oil fill cap looks brownish white. It drives fine other than extremely rough idle. I know how to check a blown head gasket with the combustion gas test.
From what I've read blown head gaskets on 4.6 fords are fairly uncommon but a blown intake gasket is fairly common. How can I tell the difference?
Ford F-150 - 1997-2003 :: Exhaust Is Pouring Out White Smoke With A Sweet Smell
I have a 2003 F150 with a 4.6. Exhaust is pouring out white smoke with a sweet smell. I have replaced upper and lower intake gaskets. Compression test on all cylinders are at 145. Confused and don't know where to go from here.
View 1 RepliesBuick - Regal :: 1996 - Sulfur Smell - Rough Idle?
I own a 1996 Buick Regal with 132k miles on it, 3.1L six cylinder. The other day I was doing some general maintenance and noticed that the exhaust smelled like sulfur (rotten eggs). Now, I am loosely familiar with the causes of such a thing but not well enough to diagnose it properly the first time. The car has been idling rough since I got it (almost a year ago now), I have a feeling that it could be the O2 sensor causing the rough idle and the sulfur smell but I am not completely sure. I should have one of those fancy three-part injector cleaners done?
View 6 RepliesFord Excursion :: 2003 - Rough Idle - Puff Of White Smoke On Cold Startup - Slight Exhaust Leak
I've been chasing a problem all summer. Began with crappy batteries dying intermittently. I replaced the batteries, FICM, finally cleaned EGR valve and replaced ICP with pigtail. The problem is still persistent. Basically a rough idle, puff of whit smoke on cold startup, rough running at around 1500 rpms( driving at 50 mph). The ICP was soaked in oil so i was confident replacing it would finally cure my issues. It actually got worse with the rough idle turning to a surging idle and quite rumbly at 50 mph speed. I guess its time to look to injector issues but i thought id check if after replacing icp/ cleaning egr. I also have a slight exhaust leak at turbo out that i can see. The clamp is not seated properly. This after turbo connection to exhaust.

I have a 98 expedition with the 4.6l 4x4 and it has 158,000 on the dash had a new engine installed at 100,000 it started running rough and sluggish last week so I changed out the spark plugs and while changing the plug I notice oil on the threads of the two rear passenger side plugs. After the new plugs it was smoking pretty bad blueish white smoke. I figured it was the oil from around the threads that had leaked into the cyl.
The smoked cleared after 2 days and ran great for a week. Now its doing the same thing again real rough idle and and its extremely sluggish. I can put the pedal to the floor and she barely wants to move almost like the tranny is going out but the rough idle leads me to believe its and engine problem. I have the check engine light on but can't get any codes. I also tried checking for vacuum leaks by spraying either round the intake and vacuum lines and didn't notice any change in rpms so I'm guess the vacuum is fine.
Ford F-150 - 1997-2003 :: Idle Very Rough Like A Misfire
I got a 97 f150 4.2l from my neighbor. he takes good care of his vehicles. he sold it to me cuz it started to idle very rough like a misfire. it is hard to start when cold spits sputters and pops. once started idles like it wants to stall, then will idle normally then back to rough. back and forth like that. runs like a champ when going down the road . check engine light was on took it to auto store they checked codes . said bad o2 sensors so i changed them. still same issue. neighbor changed coil packs checked spark plugs and wire. every thing fires good. i changed iac. still didn't fix problem. could this be a bad egr valve or sensor? if so how can i diagnose this? he also thought was a clogged cat and bored it out. tight budget can't afford to take it to a mechanic. Was told spray carb cleaner spray around engine to check for leaks that did nothing at all...

I have a 98 with the 4.2.The troubles started with popping a little through the exhaust ,bogging down and bucking,rough idle and had the two codes together that deal with having bad intake gaskets don't remember the codes offhand.
I also noticed every plug in the truck was wet and black however it didn't appear oil wet.I have changed the fuel filter,spark plugs,lower intake gaskets,plenum gasket ,injector o rings,checked injector ohms all were 16.5,new EGR gaskets,all bolts are torqued to specs
Now I have a no run condition, it will crank but not run. I heard a pop in the engine one time. I cranked till the battery went dead.I also noticed as I was calling it a day last night the radiator reservoir was empty. I don't know if somehow I got a hydro lock even though I put new intake gaskets in it or i have some other issue like timing or something. I don't know where to look next....
Ford F-150 - 1997-2003 :: Rough Idle At Start For About 30 Seconds - Cylinder 1 Misfire
2000 5.4l lariat. My cylinder 1 for 2 years has been poping p0301code and has a rough idle at start for about 30 seconds. It also has a little white smoke for that 30seconds. new cop, new spark plug, new spark plug pig tail, swapped injectors to different cylinders multiple times to change code no luck. Compression dry and wet are at 200 and all cylinders are within10%. I had a dorman intake manifold installed 4 years ago and the code came a few years after. Im thinking intake manifold gasket is bad between cylinder 1 and the heater bypass tube allowing coolant to slowly leak down into the cylinder causing my rough start. I looked through the injector hole but could not tell. With all the info I have given is there any other places or things that it could be before I do a gasket replacement or is all my tests leading to the intake manifold gasket...

My car was running rough, with white smoke and strong gas smell coming from exhaust. It died out on me a few times as if it was not getting enough acceleration. Well, I coded it and said misfire cylinder 3 and 4. I also tried to shut down 3 and 4, but did not shut down. I switched 3 and 4 with 1 and 2, still did not shut down cylinders 3 and 4. Engine coils are good, engine module was tested and passed twice. Ok, fuel injectors 3 and 4 were leaky and I changed them out. New spark plugs and boots. New oil and filter..(There was gas in my oil and oil in my air filter.) With the new parts....my car sounds soooo much better!!! still a little rough, does not bog down, but it still has the strong gas smell and white smoke from exhaust..(gas smell soo bad I had to open all doors to the garage!!) What else could be wrong?!?! I'm getting frustrated!! It also has NOT ever over heated, does not run high.

I purchased a 2011 Chevrolet Impala last year with 14,000. When the car reach 26,000 I begin to smell a very strong sulfur smell coming from the exhaust. I took the car to the local Chevrolet dealer and was told that the particles in the catalytic converter begin to break up at about 26,000 mile and the result is a sulfur smell.
I didn't believe that all Impalas had this problem. So I took it to the Chevrolet dealer in the next town where I personally know and trust the maintenance chief. He put his two best men on the car and could not find anything wrong. I was told to try another gas station which I did but it did not work. I now have 31,000 miles on the car and the smell is very strong coming into the passenger compartment when stopped.

View 9 RepliesFord F-150 - 1997-2003 :: Start Blowing White Smoke Out Of Exhaust?
2002 F350 7.3PSD, lariat 4x4 dually , 212k miles, automatic, crewcab, bone stock other than k&n filter in factory air box.
Bought the truck from used dealer with 168k miles on odometer. Drove it for two months and the radiator started filling with diesel. Had injector cups replaced. Had new o-rings on injectors and valve cover harness (both sides) at this time. While in shop they wanted to put injectors in truck but limited funds haulted that. Got the truck back and drove it for a while and noticed that when starting the truck it had a miss till it warmed up, but went away. This has been going on for over a year, but now has gotten much worse. Over the past year it has gone from slight miss to a full on dead cylinder that you have to make the truck pick up as you drive it. If you leave it sitting for more than roughly 10-12 hours you have to plug it up or it has trouble starting.
The final push from this ole girl was the other day. Left for work, normal hiccups and such from the truck. I pull up to a stop light and notice the truck is not sounding like its running correctly. No biggie it will smooth out, or so i think. I head towards work and the farther i get from home the worse it runs...
It wont pull its own weight, barely creeping at times. So i stop and check all my normals(oil mainly... just replaced hpop fittings and o-rings) and add fuel to it to get it over half tank. Start truck, still missing. Pull out on highway and dump foot to floor. It takes off only to fall on its face and start blowing white smoke out exhaust and die. It starts back but apparently I pissed it off cause from there it only got worse!!! It done that all the way to work, one time being so bad i had to stop and let traffic go by as the smoke cleared the roadway.
I get to work and check oil and it was way low. I add oil and drive it to lunch and it runs good, no hiccups misses or anything. Yay, problem solved!!! WRONG!!! Head home after sitting for a few hours and i pull out the parking lot and it falls flat of its face and goes into its dieing and such again. I limped it home and its sat in the yard ever since. Tried to start it today and after being plugged in for a couple hours it only sputters on a couple cylinders till it slowly dies. All Ive got for my troubles today has been two dead batteries...
This truck has always been underpowered as well. And gotten terrible fuel mileage (8-10 avg)... But it sure is pretty!

Ford F-150 - 1997-2003 :: Coolant Smell And Lots Of White Smoke From Tail Pipe
My DD just developed a head gasket leak. I've been noticing a coolant smell for a few days and today saw lots of white smoke from the tail pipe. I figured this is where my coolant was going and sure enough there is coolant coming from the driver's side head. I've ordered the gaskets and new bolts, but need the install.
I think mostly what I will need is the intake and head bolt torque and sequence. I will need to take a few days off work to get it done. Truck is a 2002 F150 with a 5.4L engine.
Ford 7.3L Power Stroke (1999-2003) :: Slight Miss At Idle - White And Blue Smoke From The Exhaust
Early 99 7.3. Runs ok has a slight miss at idle however every injector when unhooked makes a change. Has white and blue smoke From the exhaust. Has enough blow by to blow the oil cap off as your unscrewing it. My question is, I know engine restore is bad for these trucks but I can't afford to rebuild the engine. If I run the restore and then clean the IRP once the truck dies is this going to mess anything else up. Do you think it will by me a few months to save up for a rebuild
View 9 RepliesGasoline - Mercedes-benz - C-class :: Rough Idle / Smell Of Gas In Exhaust / Less Power Than Normal
I filled up my car at the local gas station. It had been raining non-stop for the past three days and nights. 10-15 minutes later as I'm stopped at a light, the car starts shuddering, almost stalls a few times. Rough idle all the way home.
I limp home, guessing water in the fuel. Next day I go to Advance Auto and buy some fuel additives which are supposed to solve the water problem. The guy there mentions that he's had a number of reports of similar issues from this particular gas station (it's now out of business, go figure). Additives make things better but not fully.
2 tanks of gas later now and the rough idle is much better but not gone. Car seems to have less power and sounds a little bit raspy on acceleration (not noticeable unless driving near a wall which can bounce the sound back). My guess is that one of the cylinders is not firing, maybe needs a new spark plug?
The more worrisome thing is that as the car has started running more smoothly I've also noticed a smell of gas after startup (may still be there when running but I don't notice it then) -- coming from the exhaust. This seems to be in-line with the missing cylinder theory but I'm running blind here as I don't have much experience on this topic.
The car's a 1997 C280. 130K on it. It's old but mechanically the thing has been a tank so far (Inline 6 I think) -- very sturdy and responsive. I'm hoping that this whole ordeal hasn't done permanent damage.
