After six weeks of patiently waiting, I just picked up my 2-door Sport and am enjoying the engine break-in period. However, there is a noticeable revving noise coming from the engine compartment while running at idle or slow speeds (<10 mph) with the A/C off. There is no increase in engine rpm when this occurs, so I can only guess that this might be a cooling fan switching on? Interestingly, our Grand Cherokee has the same engine, but never made that noise, so just curious what it is, and if anyone else is experiencing the same thing.
