2001 BMW 740iL Q&A

2001 BMW 740iL Question: My car stutters off & on when driving. Sometimes vigorous but mostly mild.

I initially thought it might be the tranny however now I'm thinking fuel filters since it shifts smoothly all the time. The issue is most noticeable between 40 and 60 mph although I've felt it at any speed. Also my steering seems to be very tight to me. I need to use both hands to make a tight turn? -
Answer 1
