    Idle speed

    I have read a number of times that Carb cleaner leaves residue after drying so is not recommended for cleaning the MAF sensor as it can corupt the readings. You can buy a MAF cleaning spray that leaves no residue. High milage cars can build carbon deposits in the throttle body that impede the operation of throttle butterfly flap.
  2. Your car should accelerate smoothly from 30mph in 5th, so I suspect you may have a problem. I have a six speed and will cruise at 30mph in 6th and will smoothly increase its speed without changing gear. If you want to clean the MAF, its easily taken out, two bolts, undo the electric connector and it removes. You must use MAF cleaner, it leaves no deposits left when dry, any cleaner deposits left on it will affect its operation. If the car was serviced 1K miles ago then plugs and filters should have been changed. As its done 90K miles, I would look at the throtle body, these crud up over time and need cleaning out. All these things are on YouTube if you choose to try them yourself.
  3. Don't leave it too long, if its the rivets on a badly worn clutch plate, they will score up the flywheel, which will need replacing as well (ouch).

    Yaris problem

    P0016 code definition Camshaft Position A - Camshaft Position Correlation (Bank 1) What the P0016 code means P0016 is the OBD-II generic code indicating that the camshaft position sensor for bank 1 does not correlate to the signal from the crankshaft position sensor. What causes the P0016 code? The camshaft timing is out of position due to the timing chain jumped teeth. The camshaft phaser is out of position due to problems with phaser. The oil has flow to the phaser is impeded from having an incorrect oil viscosity or partly clogged passages. The Oil Control Valve (OCV) has a restriction in the OCV filter. What are the symptoms of the P0016 code? The Check Engine Light comes on. The engine may have a reduction in power or start hard. The engine may run erratically, stall, hesitate, or run rough. The engine's fuel mileage will decrease. Note: The erratic drive complaints will vary depending on the failure. How does a mechanic diagnose the P0016 code? Visually checks for problems with the connections or wiring of the OCV, camshaft and crankshaft sensors Verifies that the engine oil is full and that the oil is clean with the correct viscosity Scans and documents the engine codes and views the freeze frame data to see when the code was set Resets the Check Engine Light and road tests again to see if code returns Commands the OCV on and off to see if the camshaft sensor is indicating timing changes for the bank 1 camshaft Performs the manufacturer’s tests for the P0016 code to determine the cause of the code Note: The manufacturer's recommended pinpoint test is used to narrow down the problem. Following the recommended tests will help with diagnosis without replacing the wrong parts. Common mistakes when diagnosing the P0016 code Not verifying the failure and codes before attempting any repairs Not doing a visual check for possible problems with the wiring or connections to the components Not doing all pinpoint test steps to help prevent misdiagnosis of good components Not replacing parts directed by the pinpoint test or visually checking them to make sure they are bad How serious is the P0016 code? The engine can have stalling or hesitations along with hard starting. The timing chain may have problems with tensioners or guides and can lead to major engine damage if the valves hit the pistons. Driving the vehicle for a prolonged time with the camshafts out of time may cause additional internal engine problems, depending on the failed part. What repairs can fix the P0016 code? Resetting the fault codes and performing a road test Replacing the camshaft sensor on bank 1 Repairing the wiring or connection to the camshaft OCV or camshaft sensor Replacing the camshaft OCV for bank 1 exhaust camshaft Replacing the timing chain and guides Additional comments for consideration regarding the P0016 code The code P0016 can be due to the camshaft sensor for bank 1 having an internal intermittent problem due to vibration or heat. These problems may or may not be able to be verified. If repeated attempts to find the failure end up in not verifying the code, then suspect a failing camshaft sensor.

    Yaris problem

    Don't get misled by the oil, if the car ran with the old oil, it was to some sense doing its job. Changing it can only help lubrication and is unlikely to cause your starting problem. I sense that the problem you have is not a simple one and will need a mechanic who knows his stuff to have a look. It seems you have a timing issue which could be caused by number things and someone needs the tools and knowledge to diagnose.
  6. Is having your Aircon fixed by Kwik Fit, getting it done by the professionals?
  7. Depends on the interval between use. A good battery should be ok for quite a time, I will guess at least a couple of months. If not I suspect its getting nackered. One thing that might help your situation is to disconnect the battery if you are going to leave the car for a while, the ECU will need to reset on the next drive but it will be more covenient than having to keep charging the battery.
  8. Cars can sometimes suffer from what's called a parasitic draw, basically its equivalent to leaving a light on when you lock and leave the car. A common one was in a boot or trunk as americans call it, light comes on when open, its supposed to go out when shut but how do you know. Look on YouTube, a good source for problem solving. But in your case, at 4 years, the battery is at the end of its life. Although it may not be the specific problem here, changing for a new one is something you're going to need to do soon and it may be the problem. I get mine from Halfords, think I paid last year, £64 with a 4 year warranty.
  9. Sorry, can't recall.
  10. Sounds like a bit of bad circulation, as the car starts, its taking a small amount of time to push the oil to the parts that need it. I think the noise you hear if you start with your foot down is the engine complaining ie. dry bearings, as the engine is running fast straight away, speed equals friction. As I posted earlier, next oil change, do an engine flush. Its relatively inexpensive and cured my similar problem.
  11. This is my opinion only and I know others may disagree, but I dont think the oil spec is that critical as long as its near, Flash is correct about Ambient Temp and age. What I do think is Important is the quality and frequency of change.
  12. If it was hard just after bleeding, then goes soft, its got a leak somewhere, look for fluid around the callipers and wheel cylinders. If you have rear drums you may need to check inside the rear drums, common to miss this one. Don't forget around the master cylinder and servo. If all is dry, you will need to check the brake pipes that run around the car.
  13. Not saying it will be the cheapest, but I've got a Halfords trade card. My local parts wholesaler gives me trade as well. Don't ask, don't get.
  14. Had a similar problem on startup,Rattle and oil light stayed on for second or so. Took a guess that an oilway may be blocked as the car had done 90k mls. Did an engine flush, this cured the problem. I've always used Mobil 5/30 Super 3000, its not a recomendation, just what I use. Its £35.50 for 5lts at Halfords.
  15. Just another thought, I don't think its been mentioned but Its important that the clutch fluid is in good condition. Its supposed to be changed every two years as it deteriates over time, plus the system needs to well bled. Any moisture or air in the system will have the same effect of not fully pushing the clutch pedal so as to not to disengage the clutch.
