was the engine fuel injected

Cadillac first put fuel injection on the '76 Eldorado- I don't know if you have the stock engine or if it has been switched- but yes, the '84 would come with FI- why do you ask? Is it having any- ummm- problems?

Yes only one injected work

I have an 89 Eldorado that has started dying on me. It acts like the fuel pump went out but, then it starts up again and goes for weeks without issues.. any ides on how to correct this before I get stranded.
