Have a 1990 Buick Regal Limited 3.1.Sat in a garage for 2 years about 2 yrs ago got it out put all new fluids in it filters started it and ran but it ran very sluggish until you reached above 35 miles an hour. Had it checked said it was between 2 sensors replaced the crank shaft sensor throttle sensor ran good for about a week limited driving and it started dieing when you would put your foot on gas petal to go. Got it up on the hwy started to pass a car and it just died going about 50 miles an hour not good now injectors are clogged have put some stuff in them to clean them out still won't start. Please help
