you dont need to adjust the linkages just the part that connects to the pedal or adjust the alda and clean the banjo bolts plus inspect the turbo for play

check the bajo bolts clean them etc adjust the alda and inspect the turbo for shaft play forward and back and ease of spin.... then start worrying about linakges

also when was the last time the fuel filters were changed.. how long did the car sit etc etc.. the linkages are set to precises lengths for the engine to operate.. no need to mess with them unless absolutley neccessary
