Hi Guys, any steer on this?......recently had cam belt change and new plugs (presume Vauxhall plugs as done at my local Vaux dealer) thinking it might help improve the engine performance - last new plugs were at 40k in 2006 with previous owner - however the tickover is now more lumpy than it was before - at its resting point at 500 revs, the engine visually 'jiggles' unhappily and the backs of the front seats take most of the vibration - wish I had left well alone. Pressing accelerator slightly brings all the harmony back.
So, can anyone guess what might have changed or been upset by having a the cam belt and the plugs changed?
Thanks

That sounds a bit like the problem I'm getting with my 2.2 after having new coil pack and rocker covers. Still haven't got to the bottom of it yet though.
-
The cambelt is not properly installed!
-
If it was my car, I would get a forum member to have a look at the timing
-
Throw it back at Vauxhall. Although probably I hiding to nothing.
Bank 246 timing is set with a non adjustable bottom roller on the late 3.2's so worth a look at bank 135.
....after checking coil pack condition. Any codes via pedal trick? Might not be, missfire has to be quite bad before a codes is raised.
-
If its just unhappy at tick over could be a Vac Pipe or Vac leak somewhere. :-\
-
thanks Guys for coming back and advice - re reply from chrisgixer, with bank numbers for timing - was is that? No misfiring just seems that engine (to use an old expressioni) is 'hunting'
-
Check the simple things first, so vac leak is a good start as said. Are all the hoses and vac pipes connected correctly. No air leaks?
Then misfires, although skip that If it's not a missing.
Cam timing, cylinders 1,3 and 5 is the drivers bank of cylinders on the v6...?
