I have changed fuel pump and fuel filter a couple months back and it ran fine, then one day it started missing real bad , so I changed the plugs and plug wires, I also bought a air filter , and put fuel injector cleaner on it , and now it wont accelarate when im driving it, it hits a certain speed and either stays there or goes, and when you try going up a hill it barely goes, please let me know what you think it might be.
why is my 1989 Buick Regal losing accelaration power when im driving it? on 1990 Buick Regal
