Grrrrr 2.0 16v stalling when hot and in traffic

Hi.

I thought this would be in connection with the damaged distributor cap.

Basically my car runs great, idles fine and pulls like a train…..However, once ive been for a good drive if I get caught up in traffic it begins to missfire (backfire even) and then stall.

If I turn the key it starts immediately but does the same thing straight away, If I keep the revs on its fine….it only happens when the revs drop below 1000rpm

It did it 3 times in the queue into VW Action today…..how embarrassing!!!

What are you using for idle control?

My right foot  

I dont know to be honest as I bought this car already done

Ok can't really help further….

OK, thanks anyway.

Im pretty good with electrics….do you think its worth my while to look down the route of the idle control?

I'd say the idle control is key to this issue! Hence, you really need to find out what's going on. It might be mixture, but I'd look at the idle and check its doing its job first.

pics of the engine bay might help us id whats the guy used when fitting the engine (or not)

Voila  





Thanks

right looks like you have a MK1 AAV where the 16v isv should go, which apparently can work ok. 1st thing is to check the valve has 12v when the fuel pump is running, and make surte the valve is opening and closing properly. give it a good clean as well.  check all over for air leaks too while you're at it, the folds in the metering head boots a prime place for splitting

think i can see the 16v ecu just poking out from under the plastic scuttle tray, along with the vacuum line to feed it from the brake servo nipple so all seems well there

Superb, thanks

im gonna spend some time on it tomorrow

Think ive sorted this problem now, thanks for all the advice.

Basically I took the ISV off and cleaned the innards with carb cleaner.

The car now idles smoothly at about 900rpm in all conditions and pretty much behaves itself!
