I have a Nissan qashiqai 2013 1.6 petrol engine recently i have changed total clutch kit but even though it taking slow pickup when i was accelerating it is slow slow pickup and hills its going very slow pickup can please help suggest me

I'm sorry to hear about the issues with your Nissan Qashqai. Here are a few potential causes and steps you can take to diagnose and address the slow pickup problem: 1. **Check Clutch Adjustment**: Even after replacing the clutch kit, improper adjustment can cause issues. Ensure the clutch is properly adjusted according to the manufacturer's specifications. 2. **Inspect the Fuel System**: - **Fuel Filter**: A clogged fuel filter can restrict fuel flow to the engine, causing poor acceleration. Consider replacing the fuel filter if it hasn't been done recently. - **Fuel Pump**: A failing fuel pump might not supply enough fuel to the engine, resulting in poor performance. Have the fuel pump checked for proper operation. 3. **Examine the Air Intake System**: - **Air Filter**: A dirty or clogged air filter can restrict airflow to the engine, reducing performance. Replace the air filter if it's dirty. - **Mass Air Flow (MAF) Sensor**: A malfunctioning MAF sensor can send incorrect air flow readings to the engine control unit (ECU), affecting performance. Cleaning or replacing the MAF sensor might help. 4. **Check the Exhaust System**: - **Catalytic Converter**: A clogged catalytic converter can restrict exhaust flow, leading to poor engine performance. Have the catalytic converter checked. - **Exhaust Leaks**: Leaks in the exhaust system can also affect performance. 5. **Inspect the Ignition System**: - **Spark Plugs**: Worn or fouled spark plugs can cause poor combustion, leading to reduced performance. Replace the spark plugs if they are old or in poor condition. - **Ignition Coils**: Faulty ignition coils can cause misfires and poor engine performance. Have the ignition coils tested. 6. **Check for Vacuum Leaks**: Vacuum leaks can cause a lean air-fuel mixture, leading to poor acceleration. Inspect the vacuum lines for any signs of leaks or damage. 7. **Transmission Issues**: Although you've replaced the clutch kit, there might be other issues with the transmission that could affect performance. Have a professional mechanic inspect the transmission. 8. **Throttle Body**: A dirty or malfunctioning throttle body can affect acceleration. Cleaning the throttle body might improve performance. 9. **ECU and Sensors**: Ensure that the ECU is not storing any error codes that could indicate sensor problems or other issues. A diagnostic scan can reveal any hidden problems. 10. **Engine Compression**: Low engine compression due to worn piston rings or valves can cause poor performance. A compression test can determine if this is an issue. It's advisable to take your vehicle to a trusted mechanic or a Nissan service center to perform a thorough diagnostic. This will help identify the exact cause of the slow pickup and allow for the appropriate repairs.

Hi , great video, I've got a Nissan HRA2DDT 1.2 engine from 2014 and I have codes P0365 (camshaft position sensor exh) and code P0341 with it, I want to swap both camshaft position sensors and can see them but it doesn't look very easy to get to them, any advice removal and replacing them would be appreciated.....

I have p0301 replaced 4 spark plugs its still misfiring but only at high rpm idk anymore

[@SanuMotorswithCharlie]

When you remove the plugs did you notice any plug tip burn out ? If not try to change coil pack and have a look. Thanks

[@messystressy]

@@SanuMotorswithCharlie I just checked the coil packs one is definitely faulty. Ordered some new ones and see what happens. Thanks for the video mate you helped me diagnose my issue I never would have thought to check the spark plugs

[@SanuMotorswithCharlie]

@@messystressy Now you know what you doing. Well done !!! If you need any help I’m here Thanks

[@jettchana7901]

Hello, I did check and have same error, I did change the plus and interchange the coil, but error still says 3
