These two small outfits are brilliant.If you want your injectors callibrated and balanced Alan is your man at Lynx and Peter Strong is a very helpful guy,he correctly diagnosed my injector problem with his ears...spot on.

have you got the separate temperature probe with the Synergy 2?, if so put it in a warm location under the bonnet, not in the intake trunking.When mine was in the intake, the cold air caused it to overfuel at idle, the new warm location fools it into thinking the engine is warming up.P.

Thanks for the information podge & greeners for the help. The car has just hit the 100K mark.

I will be contacting Alan or Peter to make an appointment for a check up, do you know the locations of both Alan & Peter

Regards
Tony

I took the car to a local garage to me (Crystal Palace) once it had the engine shield off, and the injectors removed, he found one of the copper seals at the bottom of the injector missing on one injector and it looks like someone has been playing with the injectors and had not tightened them down to correct torque and only one side on all the injectors had been tightened up!!!!:

Now running fine :lol:

Al long last I have a smooth idling car.

Hi Folks,

Similar to some of these older threads I have a 2002 CDTi which has just begun to sound a bit rough at idle. Specifically the engine is pulsing gently and the revs are moving up and down.

This is only when stationary, when moving the issue disappears, possibly due to the increased revs smoothing things out.
It seems more noticeable in drive than in park. Unsure why this would be, but cycling through between park and drive a few times and the pulsing becomes more noticeable in park too.
I do have a video of the issue but can't see how to upload it here. I'll try to add it later if possible.

Any advice much appreciated.
