Hi all.

My car (PUG 406 2.0 2000, RFR engine) has a weird problem: the Idle
speed fluctuates +/- 50rpm (you can feel the vibration, and is very
irritating). But some times, the idle is perfect.

My mechanic suspect on the coil pack. The dealer (actually I've sent
the car to 2 different dealers) hasn't found any error code. And the
last one, told me that vibration "is normal".

The mechanic has already change/clean TPS, stepper motor, spark plugs.
The car feels normal on speed, so the problem is only when idle.

Any suggestion? Thanks on advance.

Hi. Thanks for the suggestion.
I've looked for a leak and it looks fine. This vibration could be the
injectors or a bad spark plug? (already changed)
