ENGINE AND ENGINE COOLING

 Driving on a 1,850 mile trip. car engine repeatedly shut off on light acceleration from complete stop. motor light and wrench light illuminated. put can in neutral and re-started. wrench light de-illuminated, motor light stayed on. acceleration could barely be attained to keep engine running up to 45 mph. after that speed, can ran somewhat normally,. entering an expressway at very low speed with minimum acceleration became the only way to continue the trip. very dangerous. went to a ford dealer on route. because i was from out of state he agreed to work me in for service that day. however, after i described the problem, service writer refused my request to put car on their diagnostic machine. he agreed to change the fuel filter only. dealer would do no other work. told me i would have to leave it several days. i tried two tanks of fuel with a stoddard solvent injector cleaner. at home. i researched the problem. the ignition coils and throttle body are indicated. i have had both ignition coils replaced.18,000 miles ago. replacement for both was not free. this condition is absolutely dangerous and has no lead up symptoms to warn you. i have barely avoided being rear-ended several times as i tried to make it off the expressway. local ford dealer is trying to avoid scheduling my thunderbird for repairs. a recall of the defective components is necessary. a check of the internet web sites indicate this is predominant with all thunderbirds of this vintage.
