Fuel injector cleaner

What cleaner do you all recommend? My trucks RPMs go up n down at times while just cruising along the roads. No matter if it's highway or local roads. I tried HEET cause I believe it's due to bad watered down gas as to why my truck is running like it is.

I like Seafoam. Wait till you have an 1/8 off a tank of gas pour in the bottle and fill up with a full tank of gas. Also clean your throttle body with sensor safe throttle body cleaner NO CARB CLCLE. What u are describing sounds more like a vacuum leak.
