1997 Ford Ranger V6 Two Wheel Drive Automatic 151000 miles
----------------------------------------------------------------
I have a problem with my 1997 Ford Ranger 3L with 151000 miles. The code P401 indicates "insufficient EGR flow". The EGR vacuum regulator and EGR valve have been replaced. This did not solve the problem. At about 1/3 throttle the motor lopes or surges. The vacuum line can be disconnected from the EGR valve and the motor smooths out. Reconnecting the line causes the problem to reoccur instantly. There is six inches of vacuum at the EGR valve.
Any advice will be appreciated.
