engine hesistation under acceleration
My 2007 Focus has recently started hesitating under heavy acceleration when it gets to about 60-70 MPH. It is pretty subtle and has happened only twice. My wife's 2007 Freestyle had something similar and I solved it by taking off the throttle body and cleaning it.
Has anyone had something similar happen with their focus and what did you do to fix it?
I had it in the dealer for service and they could not replicate the issue and would not give any advice on what it could be.
Thanks in advance!
