Rover V8 power problems TVR 4L

Hi,

I have a bit of an issue with my V8S. It was SORN for over 5 years while my son was a baby and didn’t really move much, but always started ok and ran fine.

To get it back on the road I fitted new plugs, magnacore leads, rotor arm, dizzy cap and new vacuum advance. I also fitted a new thermostat and did the usual service stuff.

It went through its MOT fine, but the power delivery is now odd and not what it should be. It takes off ok, but then loses the initial burst of acceleration in any gear. I will keep accelerating, just at a slower rate. Before it would just keep going and going. You can pump the throttle to get it to accelerate faster throughout the range. At first I thought it may be the timing advance, hence the new vacuum unit, (it does move the rotor arm when I apply vacuum.)

Now I am thinking some kind of fuelling issue, but what. Any ideas / hints would be appreciated. I have just ordered a fault code reader (Steve Heath’s), btw.


Car is a pre-cat 1992 TVR V8S
