Accent LC (2000-05) :: Gas Consumption Too High 7.3 Km Per Liter - Spark Plug And Air Filter Replaced
I have a hyundai accent 2005 sedan (automatic transmission). The vehicle is a NON-US model. My gas consumption is approximately 7.3km per litre which is very high.
The spark plugs have been replaced , tires are at 30psi , and air filter is new. The spark plug cables are also new. The obdII device does not detect any issues and the engine check light is also off.
Accent LC (2000-05) :: 2001 - Transmission Sometimes Downshift From OD To 3rd Gear And Stay There
I have a 2001 Accent with a 1.6. This car is mostly driven by my daughter so I'm translating the symptoms as she has described them to me. The issue appears to be this - when driving at highway speeds the car will sometimes downshift from OD to 3rd gear and stay there. When the problem first started, she would pull off the highway, turn off the car and then restart it - this would appear to "fix" things temporarily, however, as time went on, it would work up to (and including) 3rd gear and not go into OD after a restart.
I've reviewed the various threads on this site describing the 4th gear problem prevalent in the Accent, but in each case that was posted, there was a check-engine-light or at least some diagnostic codes stored that one could refer to - I've scanned this car every time she's been home and there are no DTC's. Should I assume that this is the standard "4th gear" issue and take the pan off for investigation or could this be some other issue such as the speed sensor causing the transmission to limit itself to a max of 3rd gear?
Gmc :: 2000 - Transmission Malfunction - Reluctant To Shift Down
Driving at cruising speed in 3 or D, encounter a hill and the truck shudders and bucks in same gear... then will finally downshift and everything is fine. The high miles 232k may be the issue of course. But does this thing have a vacuum modulator or something on the transmission that I can replace besides the fluid and filter that will fix this reluctant down shifting problem?
View 4 RepliesPrius (2010-12) Fuel :: High Fuel Consumption While Coasting With Charge Available?
When I go out to do errands around town (I live right in town) I get horrendous gas mileage. Now, I understand gas mileage is high at the beginning of a trip, but for this long and this high and under these circumstances? I'm getting ABOVE 10l/100km when I have 80% charge available (for americans, that's disgustingly high MPG like, pick-up truck high), AND my foot is completely off the gas. Literally, coasting, or braking, and I'm still sucking up gas. What the heck?
Is this just because it takes a certain amount of time for the engine to run no matter what or something? I still don't see any reason for me to be eating up all that gas when my foot isn't even on the gas AND most importantly, I have charge available. Feels pointless for me to use my car for what I use it for 70% of the time, which is for quick errands around town at low speeds. Thought the prius was suppose to be a superstar for this kind of thing.
Elantra MD (2010-15) :: High Fuel Consumption Above 2200 Rpm?
It's great on gas below 2200 rpm. Averaging 34 combined. However whenever I'm in a situation where I need to accelerate, such as beat the yellow light, up a hill, or pass someone and I shift to a lower gear I lose 1-2 MPG at the drop of a dime. And then it takes forever to recover. What is going on here? Is the engine being flooded with fuel?
View 28 RepliesPrius (2010-12) Fuel :: Display Consumption Bars Too High?
Just bought a 2012 Prius Three last Friday. The MFD (upper display) shows an average of about 53 mpg so far, and the corresponding 1 & 5 min bars seem to make sense (we have an 07 TCH so we're reasonably familiar).
But the Display Audio unit (6.1 inch) Car>Consumption graph seems to show 100mpg most of the time/most bars. That can't be right and it looks nothing like the MFD display. What am I missing?
Elantra XD (2001-06) :: High Fuel Consumption And Preventive Maintenance
I have a 2002 Elantra GT, is consuming 22 miles per gallon, one of these days the car was alarmed with a check engine, the mechanic checks to see if he had a loose wire, then removed the battery, put it on again and check engine disappeared. Following this, the car is doing 30 miles per gallon. After 5 hours the alarm appeared again, we scan the car and gave the code P0420. These days the car has been decreasing again the miles per gallon.
I bought the car with 186.000 miles but the person who sold me the car said he had 68.000 miles, the board was stolen and damaged something, then had to buy a Yonker the board and that board came with the mileage, is this possible?
What is suggested to improve the fuel consumption?
It is possible to know how much mileage the car has traveled in reality?
With so many miles traveled, which recommended preventive maintenance?
This error code says that the catalyst has to be replaced but can also be a leak or may be some of the oxygen sensors.
Elantra XD (2001-06) :: TPS Failure Symptoms And High Fuel Consumption
I'm experiencing some TPS failure symptoms and high fuel consumption.... I've unplugged the ecu harness to measure the voltages, measured a constant 6v on the return signal wire while it should be about 0v. While the input voltage is normal 5v. A strange reading as well is that signal reading with both battery terminals is 6v!!
Would this be a short on the ecu cable or is it a corrupted ECU? Also today I had tough hesitation in the morning while the engine was cold, after warm up it was normal! Is this related or its idle sensor?! ( Plugs and their cables are new)...
Golf IV / Jetta IV :: VW 1.6 SR (AKL Engine) Rough Running / High Fuel Consumption
Regarding my problem (outline below):
>> Went for a refueling stop, and thereafter proceeded onto the highway
>> Approx. 500m into the drive onto the highway the car started jerking and running rough with an initial puff of smoke (none thereafter)
>> Immediately after this initial jerking/shuddering there was a significant increase in fuel consumption i.e. from a familiar 8.2L/100km to 18L/100km in the cruise
>> We continued driving not knowing what it was (I suspected a spark plug may have stopped working)
>> Pulled up at the gas station to observe what went wrong inside the engine bay - no signs of any leaks, fuel sprays, etc. but only that the engine was shaking
>> I checked the rear of the car while the car was idling and observed a pulsating sound...some light smoke and a fuel-rich egg-like smell
>> Asked around and I was led to think the catalytic converter was ruined, so the next day I had the catalytic converter cut out
>> After removing the catalytic converter the problem persisted...although the engine operated with slightly less flow resistance
Attempt at diagnosing the problem
>> My wife called in a technician from BMW at Canal Walk to come have a look and what errors were flagged
>> The tech ran the diagnostic and no fault codes were indicated, except a few short circuit faults due to my incorrectly placing -ve on +ve when I tried to charge my cars battery with jumper cables
>> He proceeded to ask if we changed the spark plugs, I said yes. He then looked at the oil on the intake manifold and said there could be a torn valve on the intake manifold and that air that is not measured by the air mass flow sensor is entering the engine, which is causing the car to rev hunt (this problem of rev hunting has been with us for a while). The engine also shuts down uncommanded at stops and sometimes between shifting gears with the subsequent loss of power steering (very dangerous!!)
>> We also had the O2 sensor replaced a month before this occurence

Went to Cape City VW in Cape Town and the part number for that orange thing/diaphragm is 06A 198 205A 'Repair kit for valve'. Is this significant? The car sounds as strange at idle...as if has noisy valves. I can upload (if there is an option) a sound clip of how the car sounds if this assists.

Touareg :: Loud Clunking / Transmission Locking During Downshift At High Speeds
My 2004 V8 egg is currently at 111,000 miles and I'm starting to have problems that are really cause for concern. Since the blue book value on the Touareg is worthless and I've got it paid off, I might as well keep it until the wheels fall off of it. Anyhow, on to the problem at hand ...
When driving on the interstate at high speed somewhere around 80 - 90 mph and you push the accelerator to get that extra bit of speed out of the downshift so you can pass or just for the heck of it, the transmission starts clunking, LOUDLY, which of course causes you to let your foot off the gas. The clunking continues for about 5 - 10 seconds until the car has slowed down a bit.
I can still get the car up to speeds of around 110 mph (my wife tried it just about 15 minutes ago on our way back from Florida), but it has to be done gradually as to keep the transmission from downshifting.
Around town the car responds fine. Occasionally it will have a hard shift, but I can't find a reason or pattern to that. Fifth gear also works fine in city traffic, I've used tiptronic to keep it in 5th and I've also watched the main display change from D4 to D5 to D6 and back again without incident.
I'm too afraid to take the car up to 90 and then engage tiptronic and downshift to 5th. This transmission has had its fair share of problems. I'm on my third stepper motor, the forward transmission seal had to be replaced and then later the hydraulic pump had to be replaced. There are no noticeable fluid stains on the belly pans and there are no stains on my garage floor, so I doubt its leaking fluid. Can you even check the transmission fluid level in this thing?
Other than the transmission problem, the Touareg is behaving fairly well. (Knock on wood) It still rides nice and I've learned to put up with the little electrical anomalies that happen like the blue strobe backlight compass (it's just dancing along with the music) and the lights switching ON in full daylight (with the euro switch installed).
Prius (Gen 2) Fuel :: 2005 - Fuel Consumption Increase After Service And New Brakes
So, my 2005 Gen II Prius went for a scheduled service on Wednesday, 70k miles, Toyota main dealer. They called and said it needed new front brake pads and disks, I was surprised but gave the go ahead. There would occasionally have been a mild squealing sound from the brakes at very low speed so I accepted the pads might need replacing, I was surprised the disks needed replacing but it hard to argue about brakes, especially as I only have the car a year (I'm the second owner and it has a full Toyota service history). It had a "major" service, new spark plugs, new front brake pads and disks.
Since collecting it I've noticed that the engine seems to kick in more often and needs higher revs. The fuel consumption seems higher, normally mid 50's MPG (imperial gallon) now 35MPG. However it hasn't been driven many miles since its been serviced so its a low distance for calculating MPG. I've also noticed that the car seems to slow more quickly without applying the brakes, a regularly driven hill that I coast down at 48kph now only gives 35kph. Also, if I drive on a flat road for a mile or 2 and coast to a stop the front brake disks feel VERY hot, way too hot to touch, drivers side more so that passenger side.

View 10 RepliesAccent LC (2000-05) :: 2001 Car Is Idling Really High
What happened was, the car was not starting (its a manual, so I can push start). I replaced battery but accidentally put it in with the neg connected to pos post and pos. connected to negative.
The car was off when i did it so as far as i know I only blew a couple fuses. So I replaced the fuses and now the car is idling really high. So I cleaned the throttle body, still idling high.
Now, the car wont start unless pushed and I have no ac/heat (the fan has no power).
I have checked all of the fuses and they are fine. I have also tested the Throttle Position Sensor, it is fine.
Could it be the diodes, relays???

I need diagnosing a problem on my 2002 Hyundai Accent LC. When I accelerate with the aircon on the engine stops accelerating at high RPM and when I accelerate from a stand still the engine hesitates and jerks! I don't understand what the problem may be coz it works perfectly after a cold start but after it warms it starts doing that.
