The problem used to manifest itself particularly in damp weather. Living in Ireland, we don't have a shortage of those conditions. I did the old trick of observing the ht leads in dark conditions and found fireworks jumping around the place. I replaced ht leads and distributor cap and sparkplugs. That seemed to solve the problem. As the car was due for it's certificate of roadworthyness, I replaced the exhaust system which was full of holes. After this procedure a new symptom started: After driving for about 30 miles, when slowing down to stop, the engine would "hunt" to establish idling speed and sometimes even die. At the same time a green triangular warning light would come on with a lambda symbol within. A couple of miles later everything would return to normal even with the light still showing. Can someone please explain to me what this symbol indicates and what I can do to fix it. Any hints would be appreciated. Regards to you all. Bernd

Re: Volvo 460 1996 1.8 Petrol cutting out.
Likely that is a check engine light... if you have a shop near you with an obd II tester you can have the codes read. as for the test in the dark.... because of the damp condition ... try that again... but have a can of WD40 (not sure you have that in your country) basically a spray can of penetrating oil. where ever you see arcing... spray the oil... it doesn't conduct electricity but it will repel any water. also pick up a couple bottles of gas line antifreeze....it contains alchohol (not the kind you can drink unless you don't like to be able to see) it will **** up any water in your petrol.
The "hunting" rings a bell but i cannot think of what causes it at the moment... you would do well to try those things and see if that fixes the conditions you have tho.
Please take a moment to rate this solution... thanks

Hello, why type of fuel do you use? You could have water in your fuel??. If you
are living where the weather is very hot and your having to buy fuel with
alcohol 10% or more don't buy this type of fuel. Your 1988 Ford Bronco II is
carburetored, and the alcohol will start boiling causing vapor locking this Ford
Bronco II. One reason is that early model used an open fuel system and none
injectors. With the alcohol additive will low the boiling point of the fuel
causing it to boil away; therefore, carburetor can't operate on fuel vapors it
has to be liquid. GB...stewbison
Weak spark or worn out plugs will manifest themselves more under heavy throttle operation, but the first thing we think of whenever someone mentions hills is fuel delivery volume, and the first suspect with low fuel delivery volume is the fuel filter. I would replace that filter before looking any further,
If that does not correct the problem, some more in-depth diagnostics of the fuel pump and the rest of the fuel delivery system will be in order.
Could be clogged exhaust when the cat. converter goes bad it blocks the exhaust from leaving it will run until its backed up with exhaust then die, simple check have someone start it while someone feels if theres exhaust coming out of the tailpipe if they don't feel stong exhaust that could be the problem
perhaps you need a new cap and roter a new spark plug wire set. they don;t like moisture. also check to see if you have any broken or leaking vacuum hoses. the worse case senerio would be that your head gasket is leaking--at cold temps a little antifreeze will enter until everything warms up and it seals shut due to metal expanding. but since you say it's cold weather only--this probably wou;dn't be the case. good luck.
