missing on rebuild

[prestige]

my 2000 tuscan has just had a rebuild iam 700 miles in to its 1000 mile run in

the engine feels tight and very responsive(under3500 reves)

the last few miles it has started to miss fire,only when the car is at a level speed ie 30,60,90,sitting at a constant speed it keeps doing it,but never happens when pulling away at speed ,the dealer is closed now so does any one know if i should be worried or its not nothing to worry about

TVR's use to have a warning notice on the inside of the sun visor, saying if the enging misfired at all get it checked, I think they even went as far to say don't drive it. I guess they had no where to put this sticker on the Tuscan as it has no sun visors. Best to get it checked it's probly somthing quiet simple.

Could be many things but my guess would be worn Throttle pots or bodies, if it is on very very light throttle, and drives it self out of it.

defo throttle bodies.

get it checked, after 700 miles it is probably due a rebuild anyway
