Sputtering, Shaking, Fuel Restriction at 55mph and higher
Drives normal up to 50/55'ish and then you'd think the motor was falling out and/or riding on flat tires; engine sputters, loss of power, shakes and sometimes shuts off. Appears to happen even more when under load; uphill or towing.
NUTZ!!! Just happened out-of-blue on Sat.
Fuel filters recently serviced/replaced at last oil service in early Jan.
I am all ears -- lemme know if I need to brace myself for expensive repair(s) OR if this is something EZ or DIY fix.
Note: runs perfect, under load or not at anything 50mph or less
