Sound's like you are blowing the spark out on heavy load / boost.

Can you drive gently past 4k rpm without issue?

With a rica map iirc it will be at the peak of the boost map at 4k.

Try a nice set of plug's, irridium or platinum plugs dont bother with the four prong crap.

You can get through a few sets of plugs with these engines / high boost

lets us know how you get on

thanks for input were is the best place to get the spark plugs i thought they were longer than standard plug chears

**ikp_77** · Sunday 3rd August 2008, 14:23

yes i can drive it gently up to 4k like i say it only happens when i floor it

**jonno12** · Sunday 3rd August 2008, 14:27

that to me sounds like its an air issue

**ikp_77** · Sunday 3rd August 2008, 19:29

definately sounds likely.... they are not service items as far as i know so it could have been on the car from new....

would be worth thinking about getting new leads & plugs aswell...

**ikp_77** · Tuesday 5th August 2008, 22:23

yeah was thinking bout that leads and plugs he going to charge 160 for timeing belt and tenioners fitted how does that sound

**PNuT** · Wednesday 6th August 2008, 07:28

i think the parts for the job are getting on for £100 so it sounds reasonable! however, i have only ever paid 1 garage any money to do anything for me....

its also worth thinking about the waterpump when you have that lot striped down... they dont seem that prone to faliure on volvos tho so its not the most important thing to do in my opinion(depending on milage)

**Alan M** · Wednesday 6th August 2008, 07:57

Definately change the water pump when doing your belt. I never did mine the last time around and its now dying a slow noisy death. I think a genuine one off Rufe on here was about £68 quid I think.

**ikp_77** · Wednesday 6th August 2008, 17:35

had it to garage he saying it is the chip in the ecu that is throwing the timeing out he say to take it to a1 tuneing to get chip tacken of the ecu how much you think am looking at chears

**ikp_77** · Wednesday 6th August 2008, 17:40

got car back from garage he says the chip on ecu is throwing timeing out when u put your foot down he says to get it took of and just leave it alone how much u think thats going set me back chears

**PNuT** · Wednesday 6th August 2008, 21:54

dont get the chip taken out!

i would be very very suprised if it was the ECU at fault, they are very reliable!!!

is it a volvo garage looking at your car?

**Dangerous Dave** · Wednesday 6th August 2008, 22:02

Sounds like a garage who don't really care about the customer just the money.

Like as whats already been said 'Stage 0' it to make sure all the basics are ok,then work from there.

**ikp_77** · Thursday 7th August 2008, 18:08

the lad used to work at mill volvo sunderland and left there and started up on his own i got the feeling he just wanted me and me car out the way no what i mean .A lad told me to take it turbopacs at durham i got there just as they were ready to shut it cos 60 pound to get started on the diagnostics machine am realy fed up with it now

**PNuT** · Thursday 7th August 2008, 18:16

60 quid! you could have driven to mine for that & i would have checked your codes for free....

**BlackC70** · Thursday 7th August 2008, 18:20

Plugs, Leads, Arm & Cap - that's wot I'd do first. Make sure you get OE volvo stuff rather than aftermarket stuff that's meant to "enhance" it, as it very rarely does.

Get a boost gauge plumbed in, it's not a lot of cash (£20-30 or so) and will show you if it's the wastegate that's dumping the boost out at a certain pressure (overboosting) or if it's holding boost all the way through. That would give you an idea if it's an air leak, an overboost issue or something else.

It does sound to me that it's blowing the spark out, if you accelerate gently will it go all the way round to the limiter without stuttering? Also, does it do it stationary (ie revving in neutral) or only when the engine is under load?
