Shutter at high speed with load
I have a 1990 F150 with 4.9 that shutters and looses power on the highway when doing 65 or 70 mph going up hill. Runs great any other time. Could it be the injectors? The last time they were changed was at 50k, I bought the truck new. The truck has 218k on it. The last time I checked the compression it was good.
