Hello I am new to the site, I just purchased a 1988 GT (noMAF) and it is running very rough right now . It has sat for 15 years so I have changed the fuel filter, ultrasonically cleaned the fuel injectors, replaced spark plugs, distributor cap, button, but the car is still running rough on acceleration . Do you think it just needs a few hundred miles of driving with 93 octane gasoline to work out the kinks? Thank you all! Any suggestions will be great!
