Hey guy's, the old mans EF Fairmont is running pretty sluggish under acceleration, the heavier i accelerate the more sluggish it becomes. Only noticed it a few day's ago, the cars always been serviced. I'v checked the plug's & leads, the air filter and all fine. Next best thing i guess would be the fuel filter but it doesn't look like the easiest job to check.
Anyway i just thought someone may have had the same problem & could suggest what it might be? Im thinking maybe dirty injectors & if this was the case, given that its only just become a problem they shouldnt be too bad, would a bottle of injector cleaner be a good idea. Also does premium have injector cleaners in it?
