'03' Multipla SX, 1.9 JTD 115.
Hi! I'm new to the forum, and I have an issue with my new (to me!) Multipla (JTD 115) which has got a bad case of the shakes!
At idle, which seems to be around 750-800rpm, the whole car shakes quite noisily, regardless of clutch engagement, gear selection, nothing makes a difference to it unless I increase the revs to around 1,000rpm, then everything is fine and quiet again. It seems to be nothing to do with the clutch, fly-wheel, etc.
Once on the move everything is fine (higher revs!), it's just the drop down to idle revs, and everything starts to shake again!
I've read on an Alfa Romeo forum (through a Google search) where someone with a 1.9JTD engine seemed to have a similar problem and it turned out to be a problem with the fuel injectors at low rpm's.
Has anyone here suffered similar or know what I should be looking at?
I'm the proud owner of the Multipla as featured in this month's Practical Classics magazine (in 'Bangernomics'). I'm a friend of the editor, Danny, and it's had a LOT of work done on it over the past month or two in the Practical Classics workshop, including new engine mounts, rear subframe mounts, rebuilt rear brakes, new exhaust, new radiator, new track rod ends, drop links and main gearbox mount. It had a new cam belt fitted last year too.
This isn't my first Multipla JTD, having owned and loved one for ten years until it gave up the ghost. This new Multi is a very welcome addition to the family - but we could all do without the bad vibrations!
Any help would be greatly appreciated!
