Default Re: Surging problem with cougar

Still trying to sort this problem, checked the EGR valve via a method described in a pommy forum. It simply advises to diconect and block off hose to EGR if problem is no longer there it may be the EGR or more likely the DPFE Sensor. Mine tested ok. Took it for a longer run today (work 5 k from home) and it started to shift eraticly so I turned off the OD and it got worse, turned OD back on it got better. I then turned the OD off again and the OD light flashed as did the Transmission Warning Light. Drove it for another 1/2k and it settled and ran really well for the next 15k. Stopped resarted after 10 min and it again changed up and down then after 1/2k settled and ran fine for the next 15k. I am still thinking transmission problem but am not up with the electronic controlled units. I intend to try another Scan tool tomorrow to see what that comes up with. Thanks in advance.
