Rpm’s will randomly surge and rarely shut off the truck.

What is your question?

I have a 1990 F-250 automatic with a 5.8 V8. We’ve replaced a number of things on the truck. Replaced ECM, ICM, Grounds to the engine, fuel pumps, and have checked for intake leaks and couldn’t find any. I need help.

What makes this problem better or worse?

It seems worse the more I’ve used it in a day.

How long has your 1990 Ford F-250 had this problem?

Since I’ve had the truck (about 8 months).
