What to do when your vehicle is running rough

Hi, now this tip covers both petrol and diesel injection engines:

If your vehicle is running rough through all running temp range ie it runs rough when cold and at running temp.
The first thing you should do is go out and purchase a fuel line cleaner, now this you pour into the petrol tank and it then cleans all the fuel lines and all the injectors.
You can buy this from most filling stations and car spares shops a good brand to buy would be Red X this i find works better than any other brand, make sure you buy the correct type ie petrol or diesel and then just follow the instructions on the back of the bottle.
You will then need to give your car a good run for at least 30min to ensure it has worked its way around the whole fuel system.

If after doing this your vehicle is still running rough then you need to look at changing things like fuel filter, air filter etc just give your vehicle a good service and then you should find you have solved your problem
