OK, it came in because the battery warning light flicked on, so it sounded
like charging, but it is actually that the idle goes too low and then
recovers.

Any ideas on what the likely fault is. W plate 1.6 16v. 78,00 miles. No
trouble codes at all.

I am going to start with a vacuum leak hunt, go on to a throttle body clean,
then see what the MAF is doing and the TPS.

Any bets on the fault?

sorry, it is a 1.8 not 1.6

It's a bad day if you're asking, Mr C.

The only one I've ever looked at I asked about here. Turned out to be an
injector in the end.

I was asking more for fun than anything !! and no one knows all the faults,
after all someone might know it was the epicyclic dimodulator unit or
something !

I have 99 per cent identified the culprit as the MAF sensor. With it
connected the idle is hunting and it can stall, with it disconnected the
idle is rock steady . Reconnect it and it may stop or go back to a rough
idle.

My money would be on the PCV box under the exhaust manifold.

Well, I found it in the end, it was actually a tiny air leak that probably
increased when actually decelerating (extra vacuum) on the bend in the pipe
from air box to inlet manifold right at the manifold end. I initially
sprayed around the area and got no changes, but after actually feeling
around everything I started to be able to hear the leak and after that it
was easy. Interesting how disconnecting the MAF sensor made it run really
well !! That foxed me for a while.

Taxiing out at Chicago the Captain announced that "We have a light on
the panel, so we're going back to the gate". I listened to three
engine run-ups and shut-downs and hoped that it was the light on the
panel which was faulty. ;-)

I suppose it must have been...

What did you sprayed with?

Idle control valve .. I'm sooo ameteur it hurts lol. But I had a over
revving problem once and thats what it was. Actually same problem twice
secdon time was the MAF, log some live data and compare I guess.

Bet the answer has been found already, must read threads before posting hehe
