Toyota - Corolla :: Power And MPG Loss

I have an '87 Toyota Corolla, automatic transmission, 4 door sedan with 80,000 miles on her. Recently have experienced a power and mpg loss. Top speed going uphill (30% grade) is 35. Recent repairs include replacing the timing belt, fuel/water pumps, flush cooling/transmission systems, and tune up to no avail!!! So what’s left? Could it be the catalytic converter? I do live in the mountains at 9,000 ft.

Saab - 9-7x :: Sputtering 5.3L V8 - Backfiring And Loss Of Power

I have a 2006 Saab 97x. While the car is not very common, the GM 5.3L V8 in it, is. It runs perfectly fine under normal driving conditions but for the past several months it has been running like a Slaab instead of a Saab. It has been backfiring, sputtering and has had loss of power issues but only during hard acceleration.When my check engine light came on at 50k, the dealership changed all 8 iridium plugs and when it happened again at 75k, only one was replaced. Aren't these supposed to be 100k plugs? One of the exhaust manifolds has been replaced due to a leak and the other one has a leak now. Fortunately, all of the previous repairs have been covered by my warranty. Unfortunately, my warranty has run out and the other manifold is no longer covered and seemingly neither is this problem. Most recently, my new mechanic used some fuel injector cleaner something or other to no avail. I tow a 5000# camper and can't have these issues when summer comes. Is it the plugs, manifold, engine, something else?

Dodge - Neon :: 1996 - Backfiring And Power Loss

I replaced the crank shaft position sensor and it fixed everything. According to the Hanes Manual, the crank shaft position sensor is responsible for many things including timing etc. But one thing that caught my eye was that the car would run for a while, then stop completely and not run for a few hours or few days.

All seems good now. From the title post above, you can see that I have multiple issues with the car, or just maybe one causing all the symptoms.First, I am an American living in Norway and getting anything done around here costs an arm, a leg, and an extra pinky so I am going at this the maker way and trouble shooting my problems with the car.The initial problem is this.When the car starts, it starts up fine and has normal power. After driving for a few minutes, the car starts exhibiting the following symptoms.

1. If I step on the gas pedal hard and hold it, it sounds as if the car is drowning, the car loses power, then may back fire, then instantly, it regains power and accelerates. This is by keeping the pedal down.
2. If I feather the pedal, it doesn't lose power and accelerates decently but as soon as I begin to go up hill, it bogs down and does the drowning noise again.
3. I created a video showing this issue : [URL] .....

In the video, the car is idling fine but when I throttle it, it begins to drown, then just picks up right away for no apparent reason.4. Just two days ago, the car will not start after it's been running for a while. If I let it sit, it starts up again.

What it could be.

1. Could my catalytic converter be bad and therefore it somehow creates back pressure after the car warms up?
2. Would it be a fuel injection problem? I put fuel injection cleaner in the tank and it seemed to run a little better.

Toyota - Corolla :: 2005 - Loss Of Power When Get Around 3000 Rpm

I have a 2005 Corolla LE 5-speed with 101,xxx. I have owned it a year and last fall noticed that when it got cold and first started it up the car would idle hunt. While getting some warranty work done I brought it up to the dealership and they said the throttle body was dirty and they would clean it for 100. I found a local garage that will clean it for fifty. I think my new problem may be related.

I have noticed during the past week or so when I am in 3rd and 4th, haven't noticed in 5th yet, gear when I get around 3,000rpm and I punch it just a little bit lets say to pass someone I initially lose power before the car goes. It feels almost like an automatic that has a transmission slipping but it's a stick and it does not occur while changing gears. It is very brief. I lean into the pedal a bit and then the car loses power just a bit and then peps up and goes.

I am wondering if this may be related to the throttle positioning sensor having crud on it. There is also no check engine light on.

Toyota - Corolla :: 2004 - Loss Of Power / Dim Headlights And Radio Flickering

Recently purchased a 2004 Toyota Corolla in August. Last night coming home from a show (I'm a musician), the airbag light came on, my headlights seemed to be very dim.Eventually my car radio started to flicker and the mph and rxp meters as well as the odometer started to go up and back down and up while no juice from the gas peddle seemed to go to acceleration. Pulled over, car kinda sputtered like it was a dying battery. Turned it off. Waited tuned it back on and it tried to roll over but sounded like a dead battery again. The interior lights worked fine, all the of symbols (oil, battery engine) flashed but no ignition, radio or lighter charge .

After a long while tried again and it started with some coaxing, made it two more miles down the road and same thing happened, radio lights flicker, dim headlights, airbag light comes on, meters go crazy, lose acceleration. Waited a while, tried it, turned on, it turned on and we sat with it idling and same process happened while sitting there after just a short time. Dim headlights, Radio flicker, airbag light, meters crazy, slow lose of juice.

It has a brand new battery, it's a used car, I've been driving it with the check engine light on but have gotten it looked previously to disclose it was a sensor thing. Recently took it to the Toyota dealership for three recallsOne had to do with the airbags. After it was worked on the second time by them for two other recalls (one had to do with the door and I can't recall the other but am looking for the paper) my battery light came on. And has come off and on for about a week or two but with no trouble. Mostly in town driving. This trip I took was about at 40mi trip back and forth, it did fine up but coming home not so good. I'm not sure if it's any relation but that's the only "repairs" I've had done since purchasing the vehicle

Alternator? Bad battery? Electrical stuff?

Toyota - Corolla :: While Shifting Into 4th Gear And Accelerate The RPMs Drop - Power Loss

I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.

Corolla / Matrix 2009-13 :: Rough Idling And Sudden Loss Of Power On 2010 Toyota

Having problem with 2010 Toyota Corolla. Engine light comes on as well as VSC and traction control but the engine does not shut off. I loose power and engine runs really rough. I have to pull over and unplug my battery cable and the problem is gone until a week or two later same thing happens. My gas mileage is about 10 km for every 100KM city and Highway mix. The engine idle is also rough and sometimes when I try to do a U turn or get in and out of parking the engine shuts off.

Engine scanned shows P0010 and it could be three or for causes? My problem is that mechanics change one thing which costs an arm and a leg then if that did not fix the problem they say now lets change another part? I can not afford to fix them one by one and get charged for it as they replace one part at a time.

Ford Ranger / B-Series :: 1987 - Misfiring - Run Rough - Loss Of Power - Dying

My brother's 87 ford ranger 2.3L truck began to have problems. It would be running great, then start to misfire, run rough, sputter, shake and loose accelleration then die. Then it wouldn't start back up for a long time, sometimes til the next day. Little by little, the truck would drive a shorter and shorter distance between breakdowns. He first tried some minor work himself, (basic tune up) - replaced his rotor, cap, plugs, air filter, fuel filter, but that didn't fix it. He went to one garage (big mistake), who said the fuel pump pressure was fine but said he found a broken wire on the harness grounding out and it needed new ignition module and replaced it. (Cost was $350.00+), Garage promised to honor any additional work nec if it continued to have the same problem, and would be free of charge.

Five more breakdowns later and two more "better quality ignition modules", new battery terminals, and 1 new computer later, this joker did more unauthorized work and demanded another $200+ besides the fact of breaking his orig agreement "free of charge" if any further problems! Needless to say, second garage fixed the truck by replacing the magnetic pickup, part # DU 30-C (an electrical part that goes in the distributor and pulsates a current to operate the timing) (it does something like that) and the truck has been driven approximately 40-60 miles as of today, (3 days later), without breaking down. All the other times when picked up from incompetent garage, it wouldn't go more than 1 - 7 miles before breaking down and each time they didn't fix it.

Toyota - Corolla :: 2004 - Steering Wheel Violently Shakes Occasionally

I occasionally experience steering wheel vibration no matter what speed I'm traveling. It starts out as a small shake and eventually becomes nearly impossible to hold onto the steering wheel. On two separate occasions, the brakes have gone out.The car has passed PA state safety inspection and I have taken it to 3 different mechanics and no one can figure out what the problem is. I have had new tires and spark plugs installed, keep up with regular oil changes, etc.

Toyota - Corolla :: 1996 - Burning Smell / Smoke - Oil Light Occasionally?

My mechanic cannot figure out what's wrong with my car My car is a manual trans 1996 Toyota Corolla with almost 154K miles. I had the oil changed two weeks ago (about 1000 miles with my commute), and at that time, I let my mechanic know that it's been losing oil and so check it over. At that time, he changed the oil, cleaned the engine, and added a dye to the oil to show up any leaks.

I took it in this past Thursday for him to locate the leaking, and the mechanic let me know that 1) It came in mostly dry (no oil), 2) there was no visible leaking except for a seepage around the oil pan, which he says could not account for the loss of 4 quarts of oil in two weeks, and 3) it's not burning it out in the exhaust system.

A bit of the history of the car. I got it when it was at 59K, used, and there were a number of things wrong with it that I didn't discover until later, such as that no maintenance had been done to it at all in the 60K someone else had owned it. It came to me needing a timing belt, brakes, and an engine and radiator flush (the radiator fluid was brown instead of green).

At one point at around 70K, as a stupid teenager, I did let it run dry. The oil light came on, I panicked, shut it off, dumped in two quarts (which brought it to full on the dipstick, which I thought was weird), and took it straight for an oil change, where they told me it was dry, which was odd, because I'd just put 2 quarts in it.

After that, there were no issues until it hit about 120K. At that point, I started smelling burning oil and there was smoke coming from under my hood, so I towed it to my mechanic at the time. He replaced the valve cover gasket, the rear main seal, and the head gasket (with engine block machining and all). That more or less cleared the problem up, but then I took it across the country on a 3K road trip, and it ended up accidentally running dry again. Oil light came on, I shut it off, dumped in oil, took it for a lube job.

Since that time, it's been occasionally throwing me an oil light when I go downhill (I figure that this is because it's low but not out, and the change in pitch reduces the pressure?). Each time it does this, I've shut it off, coasted to a stop, dumped in 2 quarts (which brings it to full on the stick), and gone on, berating myself. These times have become more frequent, however, even though I now check the oil regularly.

So before I endure the deserved lectures about being dumb, yes, I blame myself, but regardless of my lazy maintenance, it's becoming ridiculous. My car is now finding a way to lose a gallon of oil over the course of 1000 miles, with no discernible leak or consumption.

Also, why my oil light comes on when it's only 2 quarts down on the stick sometimes, and then sometimes goes almost dry without throwing the oil light? I just got it back with the oil topped up, more dye in the engine, and instead of going for 2 weeks, I'm going for 1 week to see if maybe he can catch it in the act of learning this magic trick of vanishing oil.

Ford Fuel System :: 1987 - Loss Of Power / Black Smoke And Also Dying When Stop

So my 1987 Econoline Van was running fine until recently we noticed loss of power going up the slightest of hills and it will only hit 55 max with gas to the floor. Its shooting out black smoke and also dying when we stop. We are getting very poor fuel economy as well.

We got a tuneup, oil change, new air filter, etc. We also had a few electrical issues due to a short we thought we had fixed completely... So I'm wondering if it could be the timing? Cause it'll idle low, then high, then bog down and lose power...

Also was thinking maybe bad fuel pressure regulator or fuel pump....but how would I check this? And since we did experience a short, could we have blown a sensor too?

Ford F-150 (2004-2008) :: Slight Miss / Hesitation - Power Loss When Driving Constant At 25 - 30 MPH Occasionally

Had this truck a few years now, and it has always had a slight miss/hesitation and maybe a few codes. The timing chain skipped a tooth and the truck was down for about a year. I have 4 other trucks, so it wasn't a big deal. I finally had time to put a new oil pump, chains, guides, tensioners, phasers etc. The truck actually runs very well and quiet. But, now misses far more than I remember it doing.

When driving in town constant at 25-30 mph occasionally it will loose power for a brief moment(<1 second) and then be fine, the security light on the dash turns on for a few seconds. It drives at 55-65 just fine, unless I am going up a hill or something else increasing the load.

2004 5.4 3v 2wd
CEL-
P0453 (fuel tank pressure issue)
P0351 (ignition coil a primary/secondary circuit malfunction)
P0356 (ignition coil f primary/secondary circuit malfunction)

The coil packs are new, and I have injectors on order. Also found this thing on the back of the motor, it connects to the fuel rail on the drivers side. Where it should go. I looked on my other trucks. But my other 04-4wd has a box by the battery it connects to, but mine doesn't have any of that stuff. And my 08 doesn't have anything like this at all.

And a pix of the truck in question.

LeSabre :: 1987 Occasionally Won't Start Without Battery Disconnect / Reconnect

I have a 1987 LeSabre that will not start sometimes and if I disconnect the battery and let it sit about five minutes and reconnect, it starts right back up. Then it seems to be fine for a few days, then won't start again. When it is trying not to start, it cranks, but when you let go of the key it dies again Unless the gas is continuously pushed down.

If you keep trying to start it without adding any gas, it seems like it cranks less and less each attempt? There don't seem to be any other problems with this car at all and no real warning that this is going to happen. I can't even think of things that have been the same each time it happened. It has happened when car was warm, happened when cold. I guess it has happened after letting the car get below 1/4 tank and then refilling (sometime within a day of a fresh tank it does this, maybe?)

Ford Fuel System :: 1987 - Popping When Downshift And Occasionally Backfires When Shut It Off

All stock 460 in a 1987 1-ton 4x4. The carb has lost it's cookies I think. It (all of the sudden) developed this massive flat spot right after I shift gears and open the throttle. It falls on its face, then catches and slams the whole damn truck.

Also pop-pop-pops really badly when I downshift and occasionally backfires when I shut it off. I'm (barely) smart enough to know that it's getting excess fuel dumped through the engine. I just pulled out both float adjusters, cleaned them, and reset float levels and it made no difference whatsoever.

It's my only vehicle and it's barely drivable.

Toyota :: 1993 - Loss Of Power

Recently while driving my 93 Toyota Pickup 22RE, I experienced a loss of power. It is equipped with a 5 speed manual transmission and a 22RE engine. The engine has about 165K on it. I am aware that it could be a timing chain, or additionally, there is a sensor in the air intake that I have heard could be the problem. Also, if it is a timing chain, what are the chances of engine damage?
