I’ve been working on this issue, for some time. Hard start,no start, replacing just about everything except ignition control module? Code 0100.:hb
I’ve replaced the MAF twice; the air filter, replaced distributor to MSD unit replaced spark plugs, MSD wires, and coil, replaced CPU. car runs great and noticed some increase in power after work. I have some or a little hesitatingfrom low rpm and sometimes intake cough and rough idling. Vacuum is 18 seemed alittle low but within limits, compressions 140-150 new fuel pump.:eek:
Can’t get rid if this code. The FSM mentions the code inseveral areas. Some more advanced knowledge would be a help.
Thank you
