I have a 6.2L Turbo Diesel installed in a Land Rover Defender 90 with a manual transmission. The vehicle performs beautifully at every RPM range except between the RPM range of 1600 - 1900. The vehicle starts to buck as though it is getting intermittent fuel. A fuel gauge was installed so that the fuel can be monitored during the bucking, to see if there was a problem with the pump, but upon testing the fuel stayed steady through out the bucking range, so the only thing that I can attribute this phenomenon to is a problem with the cable or the gearing. This bucking happens with all the gears in that RPM range. If anyone have any insights to this situation, please post it. Thanks for your time!
