Re: 99 Escort lx fuel mph and horse power problems.
On a 99, the tranny should be controlled by solenoids based on the vacuum sensed at the manifold. If you get it scanned, it might pop up a diagnostic that'll point you in the right direction. When dealing with issues with automatics, I try to get the obvious out of the way, verify proper vacuum and no leaks, filter's clean and fresh oil charge, et. al, then see where you end up. If your oil is dark or acrid smelling, you may be slipping clutches, so procrastinating will only get more expensive.
