I just checked the resistance of my ignition coil. my repair manual says it should be 1.28 ohms to 1.56 ohms, mine reads 1.72 ohms, should this be replaced, and would it cause rough idle,engine knock going up steep inclines??

Depends on how accurate your multimeter is. Most are accurate +/- 2%.
I would check ignition timing and make sure you have no vaccum leaks. Ckeck the plugs for problems. I would also clean the throttle body check the PCV valve and EGR (if equipped).

Might be a good time for a tune up, plugs, wires, cap rotor, PCV valve, air filter. If your timing belt has more than 60K miles, it needs to be changed.

i did a diagnostic check on this engine, where you install a jumper and count the number of flashes that you get on the chck engine light. had one flash,pause,two flashes,, manual says it is a code 12. RPM signal, can this cause the same problems????

Check the ignition timing by jumping Te-1 to E-1 should read 10deg BTDC.

The knocking could be caused by the distributor or knock sensor not retarding the timing and creating spark knock/detonation

You're missing the Ne signal to the ECU which represent RPM signal-Test the pick up coils in the distributor-the fix here if the wires are good to the computer-distributor must be replaced
