car still cutting out even my local garage can't help!

[dom38]

Hi to all my fellow zone people.
I have asked this question before but did not get an answer or the right one that is. My car cuts out on me when it gets hot, Ive had it in the garage for two days & even they can't help. So far I have replaced the folowing: Plugs, ht leads, ignition coil & idle air valve not to mention the numerous test done by the garage. The mixture has been sorted out & a few other things. But the car still cuts out intermittantley when hot and idling. So when i'm comming up to a junction or just slowing down it will cut out and will not start for at least tem mins after.

Please can anyone help me as I am going mad here!!!!!!!!!!!!!!

cheers dom

what engine is it?

[dom38]

sorry it's a 325i 1986

Blue temp sensor?
Throttle position switch?
ICV?

[asmith88]

checked for air leaks? vacuums?

i have had french cars do this and it is normaly the fuel pump and eng ecu relay maybe worth looking into .

Hi eko sorry about this but whats a ICV?

[monkey]

its the idle control valve or idle air valve

blue temp sensor. Under a tenner at GSF. My symptoms were the same. if I interveened and dabbed the gas just once it would start to fight for revs and then stall. Another way to notice (if sure air intake is fine) is will be overfueling. might want to clean spark plugs up after changing also. This is all if memory serves correctly so might want to put this through the mechanic or another zoner. my 2p

Thats been changed today & it still cuts out. It's crazy the engine ticks over at a constant 800 rpm, not missing a beat & then it just cuts out. The revs drop off very quick and it dies! even the bloody mechanic was scratching his head!

[cliff_costa]

at a guess id say wiring loom for ingecters and temp sensors ther is a concectors under throule body to man wiring loom

could possibly be a faulty fuel pump relay.

[Brianmoooore]

When it dies, does the rev counter drop to zero instantly, or drop with the engine revs?

[psychochild187]

oh and that tells if its the relay or the engine dieing


if its the old 325 engine, could it be that early engine with the ignition module on the n/s arch by the air flow meter

do they fail?

[blingsta]

fuel pump relay !

Nightmare problem this sounds good luck

[Brianmoooore]

oh and that tells if its the relay or the engine dieing

It'll give an indication as to whether the problem is sparks or fuel related.
