V50 T5

[AlfaSpider]

Hi
I've just bought a 2005 V50 privately and its an awesome car just a few niggles I need to sort.
•Around 3000 rpm there is an intermittent misfire that's really bad and no boost. Seems to have cleared with use but it's booked into a garage for diagnostics. Is this a known issue?
•Suspension can be very crashy and under acceleration over rouugh surfaces it's really not great. Would loosing the low profile tyres resolve this?

Not sure about the misfire as it's the ME9 (ford fettled) engine but it'll be worth checking the shocks and bushes as it's not supposed to be crashy. Larger profile tyres (224x45x17") would help comfort but if the suspension isn't up to scratch, you could be wasting your money.

Thanks, it's at a ford specialist so hopefully they'll get to the bottom of the misfire. I'll get the suspension checked out as well but it's odd because it's just passed an mot. I suppose that might not necessarily show up in the test.

Your Volvo has the same floor pan and suspension as the recent Focus ST, but although it shares that same 5 pot Volvo engine and Volvo M66 gearbox and ME9 ECU, the engine loom is different and so is the software. So, it is possible that a Ford specialist may not be able to read codes and diagnose as fully as a Volvo dealer or specialist.

Don.

PS a misfire is sometimes evidence of one or more of the individual coil packs on each plug failing. You can often see tracking marks that indicate this if you remove them and check inside the sheaths.

Thanks Don, I'll see what they come up with but if I have no luck I agree a volvo specialist would be preferable. Interesting to know suspension is the same I guess this means parts are interchangeable between ford/volvo?

Turns out the spark plugs hadn't been changed so possibly the cause of the missfire. Suspension is all in order so I'm guessing it's probably down to the the tyre profile. Great car though can't fault it otherwise.
