P2 T5 strange running

[SKIDMARKS]

Hi Guys

Been a while since posting on here but still a Sweedy owner with now 135k on the clock.

Been viewing from time to time especially of late as the car has been misbehaving. Problem is apart from the hunting ( on tickover ) that's been with it for ages now, it has had a really dead spot from cold....and it really is bad. Pulling onto the road outside ours and try to get to speed is crazy.....just dies, ie press the throttle down and it's as if the ignition has been turned off, then starts to pick up.

Have changed plugs ( Volvo )...fuel filter....oil/filter. Also stopped using Tesco Momentum and gone back using V Power.

The car has been so much better not using Tesco but the fault is still there today, it was ok since going back to Shell.

Codes read is camshaft sensor fault which has been there since 18 months or more, this is the only code coming up. The throttle body was done around 18 months ago so not that.

Any ideas ? I'm thinking now it must be the cam sensor fault, but I have been told that fault could relate to the afm.

Any clues will be appreciated.

Cheers

I had engine trouble myself a few months ago, it turned out to be faulty coil packs but then you haven't got the fault codes to indicate that fault. Try resetting your fault code to see if it comes back and there will be your problem. Also, does your engine emissions light come on?

Had the code reset quite a few times and no emission light on !

Ok, well you can rule out injector faults because the engine light comes on and you'll get Cylinder Misfire Messages (can't remember the codes but they are in my misfire threads from months ago).

In that case, follow through on your DTC and go from there.

I would get that sensor done (and check the wiring for it) and see where you are from there.

[SKIDMARKS]

Yes, realise sensor needs doing...just had a price from Simon for £136.00.

Recently had a price to get the injectors cleaned as I'm sure they have never been done and just trying to rule the cheaper thing out first. I bought the car at 85k.

Can't help with injectors I'm afraid as mine doesn't have the injectors it's supposed to have. (yet another bit of the plod legacy)
However, I know it's done at least 100k on the ones it has and they're fine even though the car has been fueled on many different cheap hydrocarbons lol. (now on 192.5K)
It might also be worth getting it plugged into Dice/Vida and see if there's anything else worth knowing.

192.5K? Well, I'm showing off now, mine has done just shy of 230K. :D

martin what colour are your injectors

[M-R-P]

Brown Densos.

[ROZER]

am sure you should have blue 350cc t0 395cc not brown they are only 315cc thats a bit mad

[ROZER]

same engine and year as mine dude and mine are blue. and plod.?

[M-R-P]

same engine and year as mine dude and mine are blue. and plod.?
Dunno what plod were playing at... mine has the wrong gearbox on it too - M56LK with the 3.75:1 FDR and 23 tooth output shaft to the gearbox making the clutch nearly twice the price!

[ROZER]

yes i think you could call them brown not orange but they could have faded. but the orange are 310cc and brown 315cc are engine uses blue 350cc you need to look into that when you get your remap dude that could cause some problems.

[ROZER]

ye i remember reading your dmf problems not funny at all dude.

[ROZER]

have you got any service reports on it

[M-R-P]

Vague service sheet mate. A few notes saying "engine-modify" but no real detail. I'll try and get a pic later but the injectors aren't the usual Bosch jobbies and according to the torque app, I've never had any problems with fueling or afr.
The lads at the local stealers got a bit excited and huddled round the computer when they did the software and DIM install.
Not that I put much faith in them.

Can anyone answer this.... Why do the Police feel the need to fiddle with the original spec so much, surely these cars are fast enough and durable enough as they are? And if they're not, why use them, why not just use a different make and model? It all seems a bit backwards to me!

[M-R-P]

In fairness, the majority of plod cars are unfettled, other than the stuff added to the cars in the special vehicles factory in Gothenburg.
Only a few get tinkered-with at a local force level.
