Hello all new to the ranger world having just picked up my first one after owning a bighorn for 20 years, I've bough a 2.2 limited auto but have noticed surging at 1500 revs to 2000 revs when driving!!! I've replaced maf, changed transmission oil and filter, fuel filter cleaned throttle body and my next move is replace intercooler pipes as one was split which I sealed but none of these things have helped with my issues, I have been searching many sites for answers but wondering if anyone on here has had similar issues and sorted them?? Many thanks in advance Mark
