Great escape!

part-of-spring
The other day I had to nip out to get some materials. A bit of an understatement as it involved a journey of a hundred miles each way. As we were going up the bypass at the beginning of the trip there was a metallic clanging sound of something hitting the underside of the truck which slowed progress as I considered whether or not to stop and check. Needless to say, I didn't as the van felt and ran OK.
Ninety odd miles later. We stopped at a well-known supermarket for a break. To be met by a shushing noise. A quick look round the truck did not show anything untoward but the shh persisted; then I noticed that the rear near side tyre looked soft. In that short time, it was half flat, the air was coming out that fast. I can't believe it - another puncture! and its 
spring-in-tyre
the new one! I will not repeat what was said but I think you can guess!  
I ran round to the cab pulled out the jacking kit and got it in place just before it went completely flat. Ten minutes later the Tyre was changed.
Before we returned home, I wanted the puncture repaired, so tracked down a tyre shop and took it in. "No prob' mate have that done for you in a jiffy". Then things went sideways I saw him call over a colleague and then me. It took us all by surprise. I was told that I had been extremely lucky that it had not blown apart when it happened. The pictures speak for themselves!

Air flow meter fault, symptoms

Air flow meter.
I have written about this before in another post but have decided to write about it in its own right. I'm talking about a faulty air flow meter. The best way to find this fault is with a test drive and to listen very carefully to the driver's description. It is no good sticking the vehicle on a computer because as lots of you have discovered it does not show up in the fault codes. Have any of you wondered why? Finding this fault is down to good old mechanical detective work.

The symptoms:

In the initial stages it is quite subtle. The van starts and runs as usual and drives off as it should you then notice that you are having to use a bit more throttle than you used to get out of the turnings; this may go on for some time. Next, in the ebb and flow of traffic the van is not picking up as it should, almost sluggish in the way it gathers speed pointing to a possible turbo problem or a worn clutch in some cases. Finally driving away from a stand still is almost impossible! You have to push down the accelerator pedal a lot just to get up any speed to change up to second gear. On lifting your foot off the accelerator pedal to change gear the vehicle speeds up while you are changing up. On pressing down on the pedal again the van struggles to gain speed. It feels like it is holding back, this is because the air flow meter is not telling the 'brain' the airflow has increased.


I'm sorry to say changing the crank sensor will not do the trick but what is a good idea is cleaning the ERG valve because it will be close to being blocked if the vehicle is being used for a lot of stops start. The combination of these two things will make it purr like a kitten.

Lane hogging becomes a road traffic offence

This is just a heads up. How you drive is up to you.  I am not sure who said this to me:. Ignorance is no defense in the eyes of the law.

Middle lane hoggers to face on-the-spot fines

Drivers who hog the middle lane or tailgate other cars face on-the-spot fines of £100 and three points on their licence, under new measures announced today.
The fine for using a hand-held mobile phone while driving or not wearing a seat belt will also rise from £60 to £100.
