'LOW' as in .... the fuel low warning light was on? If so then it could well be a safety system we don't know about.

Just sounds to me that the fuel tank hasn't enough fuel to supply the pump at the rate of knots that it is needed.. :speechles Sure there isn't a prob.. :thinking: I have had it befor too.. :happy:

Fill the car up and see what happens. There was another member who had a similar problem recently, he replaced his fuel pump and all the problems went away.

Could be fuel cut. I have had a similar thing in my first VR4. This one has never done it, but it has an FCD fitted.

But it's only when his tank is low Nick :happy:

[Nick Mann]

And mine was only when the tank was low. Still felt like fuel cut as I understand it?

Put more fuel in it.

Because you are going so fast, the fuel could be moving around in the tank away from the fuel pickup lines to the engine.

Something to think about?

yeah i think low fuel is a prob will fill up tomoz and have an early spin.
thanx guys

Ive suffered from problems when on Low fuel. I was going "well-fast" and the petrol light came on, went round a bend to join the motorway, and cough, cough splutter splutter, then it "died".. when i stopped, and turned on ignition, i noticed the fuel level was well below the empty line, unlike how it was sitting when going "well-fast"...

had something similar myself recentley but didn't matter what the fuel level was. I changed the spark plugs but didn't tighten a couple down properly so at about 105-120 it would missfire causing powerlossand slight hesitation and then it would pick up after a couple of stamps on the peddle. i nipped up all the spark plugs and couple had a few turns to go, problem solved. I changeste ht leads to magnecor at same time so could of had a dodgey ht lead passing to earth. But ithink it was plugs.
