fault

Hi, my mechanic has put a new (well second hand 2007) engine into my 2006 Ford Focus but it's misfiring on one of the cylinders. He tried replacing the coil, discovered that's not the issue and is now in the process of changing out various sensors, but nothing has worked so far. He says there's not a problem with the new engine and is running out of ideas. Would you have any suggestions?

When I turn on main beam the dipped lights still stay on, making a very bright patch close ahead that makes the main beam seem dim. What do you think?

There's water getting into the plugs of my 2007 Ford Focus LX. What do I do?

I have a 1999 Skoda Octavia 1.9 TDI diesel. When the engine is cold it's almost inpossible too start. What do you think is the problem? When the engine is warm its starts directly. It is any typical thing?

My mom owns a 1999 Kia Sportage; when she first starts it up it runs just fine, but if she backs up and then pulls forward and shuts off her Kia and then tries to start it all that happens is it keeps turning over but does not start up for her. Aan you please explain how to fix this please?

Does the 2010 model Hyundai Santa Fe suffer from the same disastrous dual-mass flywheel problems as the 2006 onward model? Had to replace it every two years and in no mood to go through that again.

My 2009 BMW 5 Series 2009 estate (68,000 miles) gives a little shunt when stopping at lights or slowing down in traffic. Also when taking off, though not all the time. What could it be?

Hello,

My 1998 Mazda 323 F 1.5 petrol is using lots of coolant. Would be grateful for any help to what is causing this to happen.

Thanks! Gerry

I have a 2004 Nissan Almera 1.5 hatchback. The car is losing power; it seems ok in fourth and fifth gears, but in first, second and third it's a joke, it just crawls along. What could be the problem? When put up on the diagnostic machine, nothing shows up.

Although my 2001 Honda CR-V seems to drive very well and it starts easily from both hot and cold, the engine management light (EML) comes on; and from cold the rev counter does not operate. When the rev counter isn't working the engine is a little lumpy. After five minutes if I turn the car off and re-start, the rev counter works and the car drives perfectly.

This is an intermittent problem, sometimes the EML light isn't on, and sometimes it is. This problem has only occurred since the car has been parked up un-used for a couple of months. It doesn't appear to affect daily use once the car has been running for five minutes. The car does not over-heat. Any ideas what could be wrong? And will it be expensive?
