Volvo 940 B200FT Auto - Dies on Full Throttle
Hi Folks
Hoping you can help me out here.
On 'flooring' my B200FT auto estate earlier today (i.e. going into kickdown) whilst out for a drive, the revs got up to about 4,000 and than she started spluttering as if she wasn't getting enough fuel. When I lift my foot off the accelerator everything is fine and there's no misfire or hesitation. If I floor the pedal again, the same thing happens and she dies back until I take my foot off and then once again picks up OK. I've replaced the fuel pressure regulator with a good spare I have as I suspected this could be the problem, but it's made no difference.
I've previously replaced the lift pump in the tank and also for good measure, the under floor fuel filter (about 1,000 miles ago) to fix what I thought was perhaps a problem with the lift pump, but I actually think I'd ran out of fuel at the time with the fuel gauge still showing quarter full :-/.
I'm now wondering whether the under floor fuel pump is supplying enough fuel with the engine at full throttle. Other than the symptoms I've described above, there's no misfire or hesitation both when idling and under normal driving conditions. The car always starts first time too.
would be very helpful.
Any help or suggestions as to what the problem might be would be very helpful.
Cheers
Graham
