Why is my 1989 Buick Regal keep dropping in speed when I drive it, I have changed the fuel pump and filter a couple months ago and it ran fine, now a couple months later its missing real bad, so I changed plugs and plug wires and air filter and put fuel injector in it and now when I drive it, it hits a certain speed and stays there or it drops down, it also goes really slow up hills. Please let me know what anyone thinks might be wrong with it. Thank you
have the same problem?
