I put in a new battery and now the speedo rests on 20km/h. Tried the Jeep reset to no avail. Also the cruise control does not work, dash lights come on indicating cruise but do response from the switches. Also are these pron to head gasket failure.......

Changing spark plugs, it runs petrol and injected gas, what would you recommend?

Any help is appreciated, and look forward to coming to the meeting on the 7th.....

Anyway its better than the Hiluxs and Troop Carriers I have had.
