My dad has a problem with his 206 HDi SW 1.8 8v...
The car starts and runs, and drives perfectly fine.. However, when the engine is idleing, the engine has an excessing Rocking! so much its rocking the gearlever...
If I lift the revs above 1800 revs or so it smooths out..
I put the Lexia on it and got a Parameter Reading on the injectors and got the following results:

As you can see, Injector 4 has a very unusual HIGH reading on the MG/Flow correction.
I can also hear a slight mis fire sound in the exhaust..
Is this screen confirming we have a faulty injector on No.4 Cylinder??
Cheers
Paul
