Hey guys i have a 05 dodge magnum rt awd. Since the day i bought it at 109000 miles it does this surging thing i cant seem to understand. When i give it a little gas while cruising about 45-60 the lights surge with the rpm. At wot it does fine and iv noticed my mpg is crap. I plan on installing a MDS indicator light but i do know when i first bought the car i was getting about 27 a gallon now im at 18-19 mpg. No CEL. Thanks guys.
