Thought it might be worth a shout here to see if anyone had an idea what was up with my car...
It's a '98 Volvo V70. Last Christmas we changed the fuel filter as the engine was occasionally cutting out when idle, and I was seeing brief losses in power whilst driving along. After changing the fuel filter, everything was grand.
I've started seeing exactly the same problems recently - cutting out at idle, and loss of power. Only this time, it's much more severe - I limped home tonight, and lost power around 2000-2500 rpm in 2nd and 3rd gear on the way back. After getting home, I started the engine and let it idle - and it immediately cut out. Left it an hour and it fired up and idled no problems.
When it does start to lose power when driving, I find that if I put my foot down, I'll get power coming back.
I'm thinking atm it could be one of two things:
- fuel filter needs changing again (although I'd be surprised it needs doing so soon). Makes sense if the engine is ok after sitting for a while, presumably all the crud in the filter is washing back out again?
- fuel pump relay is maybe bad - would explain the intermittent loss of power, but I'm not sure why it would be ok after letting the car sit for an hour or two.
Any petrol heads on here care to venture a guess before I have to take it to a London Volvo dealership??
