Ford Excursion :: Knocking When Full Throttle - High Fuel Consumption?
Jul 23, 2015
It's time to do some oil change and is using 10w30 synthetic but the truck is eating fuel like crazy and I can hear some kind of knocking when full throttle .
Sparks , boots and fuel filter is new . The mechanic said I should put some lighter velocity oil . truck odo 130k v10 hot hot weather .

2003 Santa Fe, about 142,500 miles, 2.4L, 5-Speed Manual. It appears that oil consumption is 1 quart per 2500 miles.
No leaks present that I can see, no smell, no visible "smoke" from exhaust. I change my oil every 3K, so this doesn't seem too bad for the age and mileage.
Other issue: Throttle seems "sticky", especially when accelerating from lower RPM (under about 1700). I notice this especially when accelerating out of a corner in 2nd gear: If I'm attempting to climb a hill, she'll begin to hesitate as if the throttle isn't responding properly. I'm thinking it's more me, as I've recently gone from driving a 2000 VW Passat V6 to this Santa Fe with less horsepower moving a heavier vehicle. If I keep the RPMs above 2000 or just give the throttle a good press, she'll (usually) not "buck" or hesitate. Is there something I can check for? I've never really experienced this on other 4-cylinders, but those I4's have always been small cars.

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.

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?

I replace all my spark plugs but my car still has no power and its eating gas like crazy.

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?

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.

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)...

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
The images attached (#1- #3) are marked up to indicate the component I am referring to.

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.

I recently bought my new car through a family friend.2000 Hyundai accent auto owned by a 90yr old grandpa since new with only 45k on the clock. im used to driving a manual so I don't know if its just me not used to it but when I slow for a corner to say 15-20km/hr and accelerate out the transmission remains in 3rd gear unless I give it a really good prod then it changes to 2nd or 1st. the acceleration when It does this and stays in 3rd is ok but I just wonder if its normal or is it just burning out the torque converter. also im only getting about 380-400kms out of a tank when driving the same route my old 96 pulsar used to get 550kms from the same fuel. is this normal I would have thought this new car to be using if anything a little less.

Fuel gauge reads full all the time except when the key is off. Also the temp gauge reads low. Just barely on the mark for normal.

So I had the brakes services yesterday at a new shop in town. Normally I wouldn't do this, I like to do it myself. After I dropped the truck off I get a call a while later and the service tech tells me that the passenger front caliper is the wrong one. He says it's actually for the drivers side, but who ever did the brakes last just flipped it upside down and put it on the passenger side. So in essence, I have two drivers side calipers on the front of my truck.
I got under ther and looked and the bleeder screw is on the bottom on the passenger side. I would assume it's supposed to be on the top like the others?
So here's my questions......
1. Is it even possible to put the drivers side on the passenger side (upside down?)
2. Is it really the wrong caliper? It has been working for over two years like this with no ill effects.
3. Should I worry about it if in fact it is the wrong caliper?
I've never done the brakes on this truck actual truck myself. I really hate taking things to the shop because you never know if they are trying to scam you, which I'm pretty sure they were. I left there with only new pads...

I have a 1965 Chevrolet with the original 396 engine. When I purchased the car, I noticed the fuel pump was wet with fuel at the weep holes. I replaced the pump with a new one. This pump also leaked at the weep holes. I thought dirt may have been in the fuel tank and the check valves were stuck causing the leak. I installed a glass inline fuel filter before the fuel pump and installed another new pump. There is no dirt in the filter. This pump also is leaking from the weep holes. The pump only leaks when I give it full throttle and bring the car up well over 65 mph. I would like to retain the stock type of fuel pump. I'm wondering if the pump push rod is a replacement at some time and too long.

My R is vibrating in second gear near full or full throttle around 2,000 Rpm. It feels like a high frequency vibration. It seems to be only happening in that scenario. It's when the turbo spools up and there is a large rush of exhaust gas produced very quickly. My guess is that my apr downpipe paired to the stock cat back is the culprit. It didn't happen when I first put the downpipe on, but after the next track day it started. I don't know if there is anything to burn in inside the apr downpipe but it got louder too. Could it be back pressure from the stock cat back? It's very strange and I wondered if it is stage 2+ but running the stock cat back has felt this? I checked to see if the drive shaft was rubbing on anything and for any other visual indicators of rubbing around the downpipe and I see nothing. Perhaps it's the stock muffler. I'm just not sure.

We just past 1000 miles on our new 08 2.0T wagon and there is '0' oil consumption. The dipstick reads completely full. And...it is noticeably cleaner than our 06 2.0T after 1000 miles (after oil changes).

I know I've complained about oil consumption before on my 12' 5.0 with 42 K. I've kinda come to terms with it and figure not much I can do ? Next oil change I want to try to improve it. Checked it the other day and has used approx 3/4 of quart in 2200 K. I've read other guys post talking about improving consumption by switching brands and trying different viscosity. I'm using the recommended Ford 5/20 synthetic now.

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.

My stepmother has a 2006 Ford Freestyle AWD with a 3.0L Volvo engine. It seems to be consuming a great deal of oil. (Definitely not leaking it.) But not on a regular basis.... Within a couple weeks of changing the oil this time, it has consumed nearly 2 quarts! Other times it hardly uses any. This has been going on for a couple years now. She has taken it to the dealership numerous times and they cannot seem to find the issue. It doesn't have a "burnt" smell when I pull the dipstick either. The mileage is low as she hardly drives the car. (Under 80,000 miles) I've looked online and can't seem to find this problem elsewhere.

2002 Ranger XLT 4WD 4.0.. I was passing another car at about 55 when they also started speeding up (go figure) so I floored it and got on around them but before I lifted I felt it miss, the CEL began flashing so I slowed to the speed limit and went on to work. The light flashed for about a mile then went out. So on the way home I floored it again close to home and the CEL came on again. Got home and put the code reader on it and all it had was a random misfire so I have cleared it. The truck has new plugs, wires, etc for a complete tune-up. I don't usually run at full throttle so don't know if that would be normal for the Ranger, the Ranger was my wife's truck for 12 years and now is my DD. Need to clear this up? Thought of changing the fuel filter in that is still the original one.
