Just put in new battery in 2004 f150 5.4 and immediately idle speed dropped to 2000 rpm. Why and how do I fix?
how many min/hours are on the new battery???
Typo rpm drop to 200 at idle new battery was in for 25 min when it first did it
Was the truck running rough before you replaced the battery?
Ran just fine 169000 miles
still runs just fine idle dropped that's all I noticed
