Surging @ 1000rpms
99 2.5L Automatic tranny w/70K. I have often felt a little hesitation at idle just when I start to give it gas. Also at idle (right around 1K rpms), in drive, it will 'surge' rhythmically such as...(yes this is my best description) rrrrr......rrrrr.....rrrrr.....rrrrrr. No odd noises just surges ahead in that manner. No other issues with it at any other rpm or speed.
Have done plugs, wires, fuel filter, cleaned MAF sensor.
