Question about 1994 Volvo 850
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.
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
