Gonna be changing out my serpentine belt with a Gatorback, but I need to know the best spark plug for my WK 4.7. Thanks. 06' WK with Full SRT Exterior Conversion/22" Black 2Crave No.25 Wheels/ Vredestein 265-35-22 & 295-30-22 Tires/Tinted L.E.D.

Hi. I have a WJ 2004 Jeep Grand Cherokee Overland 4.7 litre HO V8. It has recently began surging in the engine revs both at idle and when driving. For example, at a normal engine idle the revs will continually increase and decrease upwards of 700 RPM to 1300 RPM and back down again to the normal idle RPM of about 600 RPM.
