My Check Engine Light came on 5 days after I paid a fortune at the dealer for a 100k service and brakes and tires. The last thing I wanted to do is go back. I followed this video an the one to clean the throttle body. The light was on after I drove it around and I thought I would still have to go. I then turned the car off and restarted and the CEL went off. I love the internet! Thanks for the info ZipZapDIY

Great Stuff. Thanks for your instructions and making it seem simple. Can you do a video on how to replace the trans fluid for an LR3?

I’m assuming it’s not a Karman-vortex MAF sensor on the LR3. I have a 2003 Land Rover HSE and I was getting ready to clean the mass airflow sensor and read on the back of the can not to use with that style of sensor. I did a quick search and noticed Mitsubishis and BMWs used that style.

Hi dear please o have a v8 hse 2006 and I think that my problem can be clean injectors, when start is ok work immediately, the slow running is perfect! 1000 rpm like a clock! The air filter is a new k&n! But when put foot fast the engine failure but if I step throttle slowing is good and the rpm is normal!
Please help me I don't know what to do more!

Note: if I open filter box and work engine without air filter the car work better when step fast throttle
Thanks indeed!

Is it ok to use WD40 to clean the MAF sensors?

2005 Discovery 3. My air flow sensor isn't held in by screws and it's on the front of the pipe not the top. How do I remove it?
