I've looked around for throttle body adjustment on my 89 740 gl 2.3 red block and found my answers but as far as the 3 cables (tension wires) for the throttle & the cruise control I can't seem to find anything useful! I've recently replaced the following in the last few months:

　Rear U joint
　Support boot & bearing
　Crankshaft position sensor
　Oxygen sensor
　Thermostat and seal
　Intake gasket
　Carburetor gasket
　Cleaned carburetor
　New vacuum lines
　Engine coolant temperature sensor
　Grounded main earth ground wire to engine block
　
RPM sensor
　Engine coolant temperature sensor

As I listed above, I've cleaned the throttle body/valve and adjusted to Volvo standards. But I feel like the cables have such importance and I need help!

Thanks,
Christopher
