hi all ,
recently, i changed all my crank sensor, plugs, engine oil, fuel fiter, and air fiters. as i discover the car was good and smooth for the first day. but on the second day i was driving and notice the RPM were going up and down from 400-900 RPM sometime i thought it would die on me again, but if applied some gas it was good to go. so instead, i park aside and shift it to drive gear and hit the window buttons upward and hold on to two or more button for few second to see if the idle is moving ..wow, by holding the window buttons upward and hold on to it for few second or more my RPM jump from 400-900 so this mean that all my tune-up is good but my battery juice is too low that is why the RPM shift up and down?? or should i change my battery not my drive belt...yes, mine is 1999 9-5 auto at 67k miles. thx
