I have been working on this old car for a while. I replaced the distributor, cap rotor, plug and wires. After setting the number one cylinder to TDV on the compression stroke, and tried to set the timing. The timeline mark fluctuated back and forth around the twelve degree ATDC mark on the bell housing. Does this indicates there is a problem with my idle air control motor?
I am going to replace Wii of the o-rings and gaskets in the throttle body, the fuel pressure regulator, fuel injector and the air charge temperature sensor this weekend. Should I also replace the idle air control motor? Is there a way to test a idle air control motor?
have the same problem?
