the parts are new apart from the carbs. these where from a manual choke version car and yes all the items changed because of the problem.
the electrics where checked for voltage when off and running.
the car is an auto.
the engine will not start until the engine temp has dropped from the gauge temp of around 88 or half way to nearly 1/4 of the gauge.
then it will fire run normally without a misfire..
thanks but manual carbs/inlet manifold where removed and a manual choke set up was fitted.
