LIMP HOME MODE

[cmoth 0]

Im having a few problems with my VR6. Ive just had new plugs and leads fitted but the car runs very nicely until up to temperature and then all of a sudden for no apparent reason, it loses all power and goes into limp mode and sounds like a scooby and its getting rather frustrating as it does it every day.

The leads are fine, could the plugs be faulty or is it something else?

Its a 94m corrado with coilpack.

Thanks

Start with the basics, MAF, Throttle body, Plugs and leads (again), then work on checking the fuel system, pump, injectors, press. reg.

Seems wierd it's fine when cold. Any other symptoms, smoke from exhaust, excessive engine noise?

sounds like coilpack ,have a look when dark and missing shoud be easy to see,unless its dropping out alltogether

Hi guys

Thanks for your responses. From my research on here and other forums, I would be surprised if its the coilpack, as it runs as good as gold from cold. I believe this rules that out?

I think its more of a wiring issue to be honest although I spoke with Vince at stealth today who thought it could be fuse / fuel pump related.

Im going to put it on Vagcom tomorrow and see what that revelas and get any previous faults cleared.

Keep the suggestions coming through though please!

i would of said maf? if its not the coil pack, oil vapour knocks the reading out on the maf and you lose all signal to the brain, i doubt its fuel related or it would do it no matter what hot or cold

Maybe? - Ive know someone with the same car who has offered to put their MAF in my car, so maybe I will try that tomorrow, so if it does not cure the problem, at least I know its not that.

Thanks

There are no other symptoms at all? One minute its fine, but then you feel the engine loose all power and it then sounds like a scooby and barely has any power at all?

its definately misfirin if it sounds like a scooby, if u done plugs and leads then its either coilpack or just maybe a dodgy injector? mine did it last week but i cheated and put the larger injectors on.. problem solved

if that is the case, why would it not be like that all the time?

After 15 mins or so, car fires up and runs really well again?

UPDATE - Vagcom initially revealed a load of errors, these were cleared and its come back with Ignition output 3 - short circuit to positive. This was then cleared and the car actually went into scooby mode immediately. Vagcom put back on and above message only one there.

It looks very much like it could be the coilpack, so I am going to get it changed on Monday.

Can someone give me a list of other problems a failing coilpack would cause, as before I got the plugs changed, on occasions, normally when hot, it would seem down on power. Once car cooled down again, back to normal.

If it was Cam sensor, surely it would be donw on power all the time?

Thanks again

the coil pack are made of a sort of bakerlite substance, when hot they expand and this can cause arcing or loss of power, when its cold the gap may just be smaller and there is no effect, i had this but it was only leads arcing when hot, new leads and it cleared immediately, this also cleared a slight hesitation i used to get when in low gear hard accelerating.

New coilpack is on, so far so good, although its bloody hot today so not going to drive anywhere till later. Vagcom is now clear also, so fingers crossed car should be ok.

New plugs, leads and a coil all within a week or so!

Car no longer sounds like a scooby so coilpack has cured that problem. I still feel that car is a bit underpowered although this seems to be all the time now?

having said that, I took it out tonight and it was much better, although not perfect? - Has anyone else noticed their Vrs running a bit slower than the norm in the recent humid temperatures?
