i have a 86 stanza with the 2.0 dual plug coil engine and i am having some problems with getting good spark. one morning i started the engine and it barely wanted to run and i could smell a very rich fuel condition. now it wont start at all. i pulled the #1 plug and did a spark test and it seemed to have a weak spark. but anyways i have checked all the plugs for spark and some don't seem to spark at all. i have checked both coils with a ohmmeter and also checked for good spark and they check out good. i have performed test on the IC unit with my volt meter and all the wires are producing the proper voltages with the ignition on and cranking. however i did a ground unit test on the ic unit and if it is .5 volts or less the manual i have says the unit should be replaced. i',m not sure if i am performing the test correctly. i'm not sure if i am supposed to place the probe on the voltmeter to the screw that holds the ic unit in place or if i am supposed to remove the ic unit and touch the housing itself. the other probe is supposed to go to the ground on the battery. I done both ways and the first method produces .2 volts and the other way i have described produces over 1.5 volts. does anybody know how to test your Ic unit to see if it is bad. they are very spendy and i want to make sure it is bad before i buy a new one. i have also done basic stuff such as checking cap, rotor, plug wires, and plugs. I am also getting fuel to the cylinders and the timing belt seems to be in the right spot.
