Acceleration - Repair :: Ford Expedition Slow To Accelerate / Strong Vibrations And Gas Smell
Apr 15, 2016
My 1998 Ford Expedition XLT with V8 5.4L engine has been having issues for about six months. It first started off with a strong gasoline and burnt rubber smell coming from the front of the car within a few minutes of starting the engine. Later, the whole car began vibrating and would intensely shudder every once in a while when idling. The car doesn't accelerate well from a standstill. The RPM will climb up to 3000-4000 while going from 0 MPH to 10 MPH, then it will lurch forward a bit and it pick up a little more speed. It struggles again around 15 MPH until it hit 20 MPH when it will lurch again and pick up normal acceleration. Once I try to go 40 MPH or more, the whole will start shuddering loudly and still struggles with maintaining speed. I have not attempted to drive over 50 MPH.
The best acceleration I can get is when I take 30-45 seconds to slowly press the gas pedal and work my way up to the speed I want.I was also following my father in another car while he drove the Expedition and on the highway, I saw sparks come out from the back of the Expedition's undercarriage when it climbed up an overpass. When driving over roads that aren't smooth, or when I accelerate, there is a sound from the back of the car like jangling chains or metal rods. It still makes the sound while the gas pedal isn't pressed or the gear is in neutral, so I think there is something, but have not seen anything underneath that could jangle around. While looking underneath, I saw that that some areas looked rusty, but not cracked. There is also a black piece under the engine that looked like it was made of plastic. It looked wet and oily and had a 2-3 inch opening in the center. I feel that there was supposed to be some sort of cover there.I now only drive it when it's unavoidable, usually once a week or less, and usually distances of 5 miles or less.I think the problem is with the use of fuel in the engine (fuel gauge fluctuates all the time, especially while driving on hills).

Not long ago my wife said the air recirc doesn't work any more on our '04 V8 and I had to admit that I agreed. After a little investigative driving, I noted that heavy acceleration (or uphill climb) causes V8 to tick (can hear it reflecting on passing walls, for instance) and strong smell of exhaust in cabin.
I thought it might be a manifold/exhaust system leak causing the noise and the exhaust smell. Seems to be only when driving aggressively or climbing. Soonest the local dealer can see it is 7/21 (16 days from now). You think it safe to drive?

'94 Ranger with aluminum wheels.
I have problems with slow leaks and vibrations from multiple wheels. Both problems have persisted through multiple tire changes over the years. The same shop has always done the tire changes and they tell me they've been balancing the wheels and cleaning the inner rims. The vibration went away after putting on my B2 wheels. Then swapping the rears back to the ranger wheels, 2 at a time, the vibration was back for both test drives (hence vibrations from multiple wheels).
The wheels are badly corroded at the rims and valve stems which leads me to believe it's the wheels themselves that are causing the leaks. I haven't heard of excessively old wheels causing vibrations though which is why I ask. I will likely be buying some craigslist or junkyard replacement wheels but wanted to "check in" first.

I recently put an accidental extra 4 quarts, and I know hear a low thump ie like a piston but the engine runs fine and there is no power loss, just a simple draining off the pain I hope. The engine runs fine just notice this small metallic rhythmic thump on acceleration, and deceleration.

Strange Vibrations From Engine (Possibly?) While Riding Brakes In Slow Traffic. I tried to search but didn't come up with much that was similar.

After I've been driving a bit and stop at a red light, drive thru, etc. I've noticed a strong gas smell. I drive with my windows down so I really notice it. I've searched all over the car and can't see any leaking. In addition to this, after I shut the car off for 20-30 minutes, when I re-start it, it runs really rough like its flooded until it clears itself out, along with the gas smell. The consensus seemed to be that its the pressure regulator/vacuum line. Where exactly is that located?

My wife's 2005 Escape Hybrid has recently started acting up. After a bit of driving at semi-highway speeds (say 10 minutes), when you slow down to a stop- the car stalls out (or what feels like a stall to someone who drives a std transmission car). Sometimes, it comes back on when you turn off & on the car- sometimes it takes a minute of being off to turn back on. After a few cycles of this, the engine temperature warning goes off. After each stall, the car will be ok for a few minutes then stall again when slowing down (it seems to do it when you are under 20mph only- not that I am about to try to stall it at high-speeds). It has circa 70k miles on it, and is obviously in the shop- as it is unsafe to drive. It was a warm day when it first did it (say 80deg), and cooler (50) the next morning.

Our 2010 Ford Fusion Hybrid has been great and trouble free. Recently, however, we've noticed a strong smell,like fiberglass, come from the A/C when starting from a cold engine.

We've had a run of -20 to -40 weather here for the past few weeks.
A few weeks back I noticed that when I climbed into my truck after command-start warm up for 10 minutes, and I could smell strong exhaust.
I figured it was hopefully the wind, or an isolated event.
Over the past few weeks I've used my truck for 3-4 more around town runs and every time I warm it up I get the strong exhaust smell. It's that rich, eye watering, sickening exhaust smell. I also notice a small yellow frozen puddle under the exhaust tips that wasn't there before.
It's bad in the cab, but even walking around outside the truck and the smell is sickening. I actually just started the truck and I could actually smell the exhaust smell faintly, from inside my house! This has never before occurred. Prior to this, a person could hardly tell it was a diesel by the smell of the exhaust.
Once the truck is up to temperature the smell seems to disappear, or at least lessen.

Not at the exhaust, but from the engine compartment. Have to open the windows at a stoplight. Can also smell it when I walk past the parked truck. What's up?

1994 reg cab 4.ol 13ok.. my wife just got it, been doing some small things like replaced dome light, replaced cargo/third brake light, truck starts and seems to run ok. but i get a headache in it which i believe is carbon monoxide, has a leak or something? i text previous owner, he said he replaced 02 sensors, but didnt say if they were bosch or a good brand.. also trucks has a oil pressure and coolant temp gauge fitted on by the gear shift as the dash gauges for those functions are out. Does this mean the CTS may not be working and affecting fuel/air I do not know these trucks i only just found out what this strange silver looking thing was it is the IAC, I Believe, then there is this black plastic vacuum type cylinder by the passenger side firewall, what is that? and right against the drivers side fire wall is a small reservoir type thingy, is this something to do with ABS? i do have an ABS light on, was hoping it was the bulb out on the third brake light or something quirky like that no such luck its still on after starting engine. but i am concerned about this running rich/strong smell as we really cant take it far as is it, its dangerous, may have to get a smoke test? Just got the truck, trying to get caught up..

On a recent long drive home through some very hot weather, I noticed a strong smell of gas at the back of the truck. Now, I've caught a whiff of gas before the trip but it was always faint. Figured it was some gas that dripped on fill up.
At a rest area, I go and look around see no leaks and finally check the fuel cap. Lots of pressure trapped. I ended up leaving the cap off the rest of the run home. Can't find a cause.

So I put one more extra quart or oil in accidently, and my car started being sluggish while trying to accelerate, no backfiring, just some gray smoke, then the smoke went away, and it stopped being sluggish, the boys at work are emptying out the oil right now, is this normal? Like, the car is working perfectly fine now...

I have been smelling fuel on and off for the last few weeks. I thought it was the fuel bowl drain valve so I ordered the kit for the whole fuel bowl from diesel o-rings. I did the rebuild this morning and I don't see any visual leaks. Still smell a strong odor of diesel though. The lower engine cradle is all wet and the valley is still a little wet too. Could I still have a leak and if so where to look? Could it be just wet still from draining the fuel bowl and needs time to go away?

I have a 00 expedition 4wheel drive eddie bauer. 100k miles. New tires, recent alignment, new upper ball joints and tie rod ends, recent suspension change over to passive system with new shocks. Also must note I have "newer" front wheel bearings but they were from advance auto and not the suggested Moog ones.
I have a loud clicking noise at slow speeds. def sounds like its coming from the front area. Speeds up and slows down with acceleration. brakes do not change noise other than slow it down with tires. The truck also vibrates on the highway. I notice the tires are wearing (cupping)
Is it the cheap wheel bearings? what is the best way to test for bad wheel bearings? i think they are under warranty if I can find the receipt. Anything else i should test? can it be c/v joints or something?

93 Mercury Cougar 3.8L V6 with just over 83,000 miles
l've been trying to figure out this issue for ages, but can't seem to find the root of the issue. When driving and accelerating to 40mph, the rpms drop and GET STUCK at exactly 1000rpm. Forcing the accelerator down makes the engine bog and sputter and not go any faster. No check engine lights whatsoever.
The idle is very rough and low in park (700rpm compared to the regular 900) and very low in drive (500 compared to 650-750). When stopped in traffic for a while, it begins to shudder and shake like it wants to stall right there. Now let me run down the extensive list of parts l've thrown at it, bringing only temporary results:
Replaced catalytic converter
Replaced IAC valve
Replaced O2 sensors
Rebuilt transmission (runs great, so l've ruled that out)
Replaced 1fuel injector
Replaced MAF sensor
Replaced motor mounts
Cleaned throttle body extensively
I asked a guy at a Firestone and he said that l needed a valve job. Asked another guy at another place, he said l needed a fuel system cleaning. Asked another guy under a tree, said l needed a new speed sensor. What could be the root issue? l was thinking carbon build up over 22 years maybe? Almost all 83k of those miles have been city miles...
This car is my baby, all l want is for it to be able to handle highway speeds without a hiccup. l'm keeping it and plan to see 100k hit the odometer and many more miles!

My father in-law gave us a 1996 explorer AWD with a 5.0 for my son who is 16. A couple of weeks later he's out learning with my wife and a very strong electrical smell took over the cabin. They came right home and when I got in I found all of the gauges not working. The instrument lights work, blinkers work, but all gauges do nothing. Pulled cluster and wires look O.K. behind it from what I can see. They saw no smoke, just smell, fuses look O.K.. What could cook on this vehicle that would wipe out just the gauges?

I have 1997 Mazda 626 I4 5 speed manual transmission with 140k on it.
All of a sudden I am getting a horrible reoccurring vibration and noise that sounds like I'm driving on a rumble stripe at about 60MPH coming from the front end when accelerating.
It speeds up as I accelerate.If I push down my clutch or let off the gas it goes away immediately. While turning right it will go away immediately until I straiten it back out.It happens in any gear at any speed in any weather although it seems more likely to happen when everything is cold.It isn't always there and there seems to be no rhyme or reason as to when it happens or clears up.

After the upgrade to APR Stage 1, there is a strong Gas smell in the car. The APR dealer indicates that this is normal (expected) due to the additional boost.
Is this correct. DO all of you who have the APR upgrade have a gas smell in the car? The car has a stock exhaust.

I was checking my oil the other the other day and it has a pretty strong smell of gas. The car has 2700 miles and still on the original oil. I drive about 20 miles to work one way and don't make a lot of short trips. I checked tho oil when the car was new and didn't notice the smell. Whats going on? Is this normal for a GDI engine? I will take the care in this week to talk to the service manager but wanted to get some input before i went in.

There is a strong gas smell in the car when the car is idle. Ive checked for leaks under the car, checked the gas cap and i check the engine area for any wet spots, everything good. Where else to look .
