I have no check engine light, and this happens mostly in idle now this week. My truck is a 3.0 Auto ford ranger 1998 4wd. The engine revs at 1000 which is its normal idle, it goes up to 1200, then down to 1000, and then suddenly it will randomly drop below 1000, almost stalling then suddenly it decides to rev back up , and go back to 1000. My air intake sensor is fairly new, my throttle sensor is fairly new, Whats happening? Im probably at 3500-4000 since my last oil change . I dont appear to have any vacuum leaks. This is scary.... I did have a corroded battery terminal , my battery is 3 years old and is due for a change but my alternator reading is at 14 volts consistent while running, on the battery terminals. Im so confused by this , there is no check engine light. When Im driving at 40-50 miles per hour nothings wrong, and suddenly I feel a yank, like the engine wants to bind or its like a jerk /skip. What the hell is happening?
