Hesitation with the automatic transmission 2006 Toyota Sienna

Toyota Sienna

I purchased this van in 2016 from an older couple and noticed that there was a slight hesitation with the automatic transmission when shifting from 2nd to 3rd. After changing the trans fluid and filter to 100% synthetic it improved.
Lately I’ve noticed there is a greater hesitation when cornering.
Is this solely transmission issues or could there be another problem, such as the drive shaft bearing or joint?

Most likely just transmission related since you did see a change in the transmission function when you changed the fluid and now it is showing similar signs. The best approach would be to see if there are any transmission codes stored in the computer that may indicate otherwise. Possibly a failing wheel speed sensor, etc.

The AC will not blow any cold air 2008 Toyota Camry XLE V6

My Air Conditioning isn’t working right. If I start it when it’s relatively cool outside, like 75 degrees, it’ll blow ice cold. If I then continue to the desert where it’s 105 degrees, it’ll still be blowing ice cold. BUT, when I leave it in the desert for a few hours where it’s 105 and come back and turn it on (when now it’s very hot outside and inside the car), the AC will not blow any cold air. It’ll blow like 98 degree air, not any cooler. As I drive back towards cooler outside temps, then it’ll start to work again. It’s all very strange, not to mention uncomfortable. Any ideas? A couple months ago I had a new condenser installed from damage to the old one. I’ve already tried replacing the relay.

This is common to a failing mode/blend door actuator. The actuator is a tiny electronic device that opens and closes the doors inside the ventilation system. This allows it to switch from hot to cold.

When the vehicle sets, heat and moisture tend to affect these components. And when first put in use after setting they have a harder time functioning properly.

Under powered and is consuming a lot of fuel 2013 Toyota Yaris 1.3L

2008 Toyota Yaris

My Yaris is very under powered and is consuming a lot of fuel.
When cruising in 6th gear changing down to 3rd or 4th and flooring it provides almost no extra acceleration at all even well into the torque band, the engine revs as it should but the power is simply not there, the engine itself also sounds a bit rough, like a faint scratching noise when accelerating hard. The fuel consumption has increased by 2 litres for every 100km. (I’m from South Africa, sorry for the metric units).

It has 400 000 km on it. No check engine light comes on whatsoever. I’ve replaced spark plugs, oil, filters and cleaned the MAF sensor. The exhaust system has been checked for leaks and there are none.
I’m trying to look at any other cause before taking the car to have the engine rebuilt. Do you have any suggestions as to what could be causing low power with high fuel consumption?

The Top 5 Causes of High Fuel Consumption in Petrol Engines

Below are the top 5 causes of high fuel consumption for vehicles with petrol engines.

  1. Carrying Excess Weight – One simple cause of high fuel consumption is when a vehicle is carrying too much weight, whether it has a lot of items in the trunk or in a trailer that it’s hauling. The more weight that’s being carried around by the vehicle, the more demand that is being put on the engine to generate enough power to move all of it. Whenever the engine must generate more power, it needs to burn more fuel in the internal combustion process. Therefore, you end up having to pump more gas because the vehicle uses more gas to satisfy its power needs.
  2. Bad Spark Plugs – When spark plugs get worn out, you will have a lot more engine misfires with your vehicle which will use up more fuel. You need to be sure to use the best quality spark plugs possible, so you can get the most miles out of them. Iridium spark plugs and platinum spark plugs are the two most preferred types.
  3. Dirty Air Filter – There are many reasons to have a clean air filter, but one big reason is to have a strong fuel economy. If your engine is filled with dirty air, then its internal combustion mixture won’t create as much power for the engine. This means it’ll use up more fuel just to perform the most basic driving needs. So, remember to change your air filter regularly.
  4. Low Tire Pressure– The tires on your vehicle need to be inflated to the proper amount of air pressure, usually between 32 PSI and 34 PSI on the majority of economy cars. If you’re driving a vehicle with low tire pressure on any or all the tires, it creates more wear and resistance for those tires. This causes the engine to work harder to make up for the pressure loss, which means more fuel will be used to power the engine for this purpose.
  5. Bad Oxygen Sensors – Your engine has oxygen sensors which keep track of the mixture of air and fuel in the internal combustion chamber. Based on what it senses, it tells the powertrain control module to either take away fuel or add fuel. But if the oxygen sensor does not work properly, the system will automatically add more fuel even if the engine doesn’t need it.

prado-bumper

I would like to know if it is necessary to replace the Front Bumper Guard for my car. It was damaged and if the guard is not necessary I would just take it off. I have seen other Prados without this guard. I bought this car used and did not put it on.

Awaiting your reply,

No. You do not have to attach the bumper guard if you choose not to.

Steering wheel is turned slightly to the right 2007 Toyota Corolla

Toyota Corolla

My car was hit on the left rear side while parked. The other car was parked behind me and was pulling out and hit my car. The damage to the body was repaired. After getting my car back I notice the steering wheel is turned slightly to the right even if the tires are straight. I don’t hear any grinding noises or any other kind of noises when I turn left or right. The brakes and engine work fine. The engine light is not on or any other warning light. I have driven it on the freeway and on the street. I don’t notice any problems. Is is safe to drive the car? What needs to be done to repair it? Thanks.

A front wheel or four wheel alignment would be the repair needed. During the alignment the discovery of a damaged part may come to light.

This past Monday on my way to work, my car started bucking and the check engine light started flashing. I checked the code, it was P0301, Cylinder 1 misfire. Since then I have…

First I Changed the Ignition Coil Cylinder 1
Then I Changed the Spark Plug Cylinder 1
Changed the Fuel Injector Cylinder 1
Performed a Compression test Cylinder 1. Passed 185 psi
Visually inspected the wire harness
Visually inspected the vacuum hoses
Swapped the ECU

About 2 months, ago I installed a new fuel pump, fuel filter and pressure regulator.

When I first start the car, it runs fine. While it is still in park, I can rev ’til the cows come home without issue. When I put the car in gear and drive for a few seconds, I get the Flashing CEL and Misfire code(p0301 only) comes back every time. Also, I can feel the car missing, so I know its not an erroneous code. What should I try next?

I would recommend checking for intake manifold gasket leaks. It is a common failure that may cause a misfire problem. I have provided a diagnostic chart to help assist you.

2006 Toyota Sequoia sr5 would not turn over

2006 Toyota Sequoia

New rack and pinion

Well I put a new rack and pinion in my 2006 Toyota Sequoia but had a issue. I didn’t tighten the drive shaft screw at bottom. But did tighten the two on top I was going to back to tht after I screwed the nozzles in I got the one small looking nozzle but the other would not tighten for nothing it didn’t look stripped it looked fine anyway the sun was going down and I had to get ready for work so I thought to my self I could tighten the one screw on driveshaft and put the nozzle in with my tires on ground anyway.

I put my tires on and took it off the jack and stands and started working on the nozzle which I couldn’t get to tighten but as I’m looking up I see the driveshaft screws are turned the opposite direction, and even tho I didn’t get the nozzle on all the way I just wanted to try to start my truck it would not turn over my truck always turns over all the lights lit the dash and made a weird sound but not even close to starting
You
Do u think there’s a problem tht my screws for my driveshaft are turned the opposite way in which I can’t reach is the reason my truck won’t start or the nozzle not in right or both

Would not turn over

No. I think your battery drained while you were working on it. This is VERY common. Fully charge the battery and the vehicle should start right up as normal.

Your lights and radio will work fine with a weak battery as they require as little as 5 to 15 amps to operate. However a starter requires upwards of 200 amps to operate correctly.
