I noticed a while ago when driving. If you are coming to a stop and hold the clutch down while braking the revs would fall as normal but the fall below the idle point for a split second them rise back to the idle point. When it drops below the battery light comes on and then goes back off once it's ideling correctly again.

It doesn't do this all the time just now and then. Wasn't really a big problem but the other day when it done this it actually stalled the engine. It's started first time straight after but was just a little concerned.

I've done a search on here and noticed a few people have had the same problem but no one seems to have mentions a solution for it yet.

I'll probably just the get idle control valve replaced first to see if it makes a difference but people with the same problem have already done this and it hasn't solved their problem.

 

What dump valve is fitted to it? if its atmospheric this is your problem.

 

Car is standard apart from a decat.

Do you think it might be worth changing the DV pipes with silicon replacements?

 

If you look at the inlet manifold, underneath the throttle body the will be a breather pipe, check this for splits or if its even still on.

 

Thanks for the help

Its a bit dark now. I'll check tomorrow.

Anything else I should be looking for?

 

Id check any breather pipes bud, ones that go to the dump valve and ones at the back of the inlet. Also check the dump valve itself, it could be sticking.

 

Thanks mate, I'll update this tomorrow and let you know how I get on

 

So had a look today and couldn't find anything obvious. Well obvious to me anyway. I have found another problem though

Where the down pipe connects to the turbo I can feel a lot of air escaping. To me it looks like it's cracked all the way around the weld. So I took some pictures to see if you lot can confirm this or correct me.

 

well...u dont have to be a rocket scientist to understand that it is cracked...?and all the way round it seems.

 

I had similar problems on mine mine was the main battery earth to the body was corroded and loose also they never run well on less than quarter of a tank and that cracked decat won't help either get a bcs one on there top bit of kit

 

I have found one of the pipes to be split under the inlet manifold. Is this a ford only part or is there an alternative from the motor factors for instance?
Cheers

 

Graham at car parts express sells the inlet pipes

 

Car parts express? Where's that mate?
