If you care about torque specs, go to your nearest Auto-Zone and spend $20 on Haynes manual #36071. It covers 1993 to 2008 Rangers and Mazda B-series trucks. Each chapter has torque specs for all bolts in that chapters topics.
This is the link to Autozone DIY section. It has all the torque specs for the entire 1.9 engine and others. Copy and paste it in your browser. http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c1528008db67
They are 43 Ft. lbs
You have to turn them twice. The first turn is 61 psi. The second turn is 72 psi.
8-9.5 in./lb torque
sequence is from the center out. torque in 3 stages. first 25 ft lbs second tighten 90 degrees [1/4] turn third tighten 90 degrees [1/4] turn. you're done.
16-19 pounds torque
12 ft/lbs but its better to use 1/4" torque wrench set at 144 in/lb so you don't over tighten.
You did not mention if it was the intake to the cylinder head bolts (1993 buick lesabre 96 in-lbs)..... or ..... the intake upper to lower bolts ( 1993 buick 132 in -lbs) but i hope you will know wich you are looking at since there is a large difference in torqe.
