my truck idles at around 750rpm and sometimes hesitates a little when i accelerate. i was wondering if some type of sensor might be bad or something?
I’m not sure how you think that anyone is supposed to help you out if you don’t tell people stuff.
What year is the truck? How many miles are on on it? Does it have new spark plugs? Wires? Filters? etc. Has the transmission fluid been checked? Service history? Etc.
750 rpm is a pretty normal idle.
You could be driving a Mack Truck diesel or a little Ford pickup gasoline engine. As noted, we need more information.
2005 f150 v8 5.4L, 51,500miles, no new plugs or wires, I bought it used.
