87 325es - Surging through acceleration
I have only had the car a week so I was hoping it was bad gas from Arco or something...but I am now halfway through a tank of Chevron 89 octane with a full bottle of Techron and still find this behavior. It is most noticable between 30-45 mph. As I accelerate normally with about 1800-2000 rpms...you can feel the slight surge of say 50-100 rpm. Once I hit 50 and am in 4th gear it is not noticable at all. I have also noticed this very easily going up hills. Any suggestions? New fuel filter? New fuel pump? Chip issues? Thanks, Ted
