Removing the battery causes the computer to de-program. With the engine and ignition swith off, try removing the negative battery cable. Wait a while then replace it. Wait only a minute or 2. This will reprogram the computer . You may have to repeat the process a couple of times. If not the idle position sensor could be the problem.

Hi my renault megane scenic has the engine light on and it is shaking it was plugged into a diagnostic tester and it came up with an anti pollution fault any ideas


Hi i think the problem is one of the coils ( very common on renaults ).
The shaking is the engine missfiring.
Because of the missfiring the emissions are not correct which brings on the engine light.
If you are able to get a diagnosis ( code reader ) done on the car it will tell you which coil is gone
I hope i have been of some help to you

Hello there, i have BMW 525 E39 Car... the car engine is shaking while idle but smoother when i drive. at workshop, we checked the spark plugs, Coil, exhaust and change fuel pump. at diagnosis it says...


There's a handful of possibilities. You said you checked the coil? There are 6 coils - one per cylinder above each spark plug. Regardless, you say it runs well when driving, it's at idle when it shakes - indicates a vac leak. Check the inlet tube (large rubber hose to intake) for cracks, also check all smaller vac lines in and around throttle body, Inside throttle housing is a fine mesh screen that could be clogging up. Also depending on mileage, you might have the injectors cleaned, they will get gummed up and stick at idle/low speed.

It sounds like one or both of the drive axle inner joints are worn out. This condition will give a very pronounced vibration on acceleration only and will be worse with increased speed.

Cleo 1.2 16v car feels like missfire light shows


Probably dirty fuel. If you use supermarket fuel try using Shell V-Power or BP Ultimate for a couple of tankfuls. You may find that it's actually cheaper in terms of pence per mile as well!

Acceleration - cannot get above 40 miles per hr.


If the engine revs up while in drive and running at 40mph, your transmission is probably slipping. Try checking your transmission fluid level. If it is OK, I would get it by a garage to have them look at it to cofirm.
