Hi

Driving a little hard this evening, something went pop and the engine management light is flashing - still starts but has no go in it at all (limp home?).

Sounds like it's either backfiring or limiting, I can't tell as I've never heard it before !

I can't see any water/oil/smoke coming out of any crevices/exhaust, so hopefully the ECU has just played it safe ?!!?!

Took tomorrow off work to take it to Volvo, fingers crossed I haven't blown anything

Have a look under the bonnet before you go,Might be a hose blown off or something simple.
When you say pop,As in a noise?or just in general speaking?

Pop as in noise, bit like hitting a bump stop.

Investigation starts now !

I had exactly the same thing - it ended up being a 3 inch split in a weak airhose. Something like that should be fairly easy to find. If it's causing that many problems it's likely to be a bigish hole in one of the bigger air hoses. Should be easy to find and fix.

:shhh: hairline crack on spark plug !

Reported by VADIS as "misfire cylinder 2" - good stuff !

All good now.

I'm taking this as a one off, as the plugs were recently changed, it could just of been a dodgy one ! If more start to go, I'll consider getting boy racer plugs (joke) !

worth getting the iridium version ?

My last set of EVX's that came out recently looked a bit overheated. Iridium would be worth a try for sure.

I think VT have both types - I think they are about 30 for the set?

10 each from Spark-plugs.co.uk.

I'll find out what plugs my mate at work runs in his Cosworth Caterham.

Won't the Caterham place completely different demands on plugs compared to our Volvos?

Not sure tbh, but it runs a massive turbo producing 600bhp last time I asked !

Don from Kalmer Union has recommended Bosch Silver plugs . . . where on earth I can find them, still searching! Hoping Camberley Autofactors can get them in !

Personally - I think you are better off without Don Norchi's advice.

NGK are just fine.
