93 4.9 injector question
what would be the symptom of a faulty injector or injectors on a 1993 4.9 I6. it cuts out real bad under 45mph but seems to run fine at highway speeds or atleast it's not noticable. i've checked fuel pressure and it never fluctuated while the symptoms occured. also it idles fine. i've also replaced the fuel filter. with no change.
