Hi. Am trying to set the timing on my 1991 toyota truck. I heard that there are some other procedures involved...something about vacuum advance but there's no hoses on distribuitor...also I heard about unplugging something, but I don't know what I have to unplug...please help with this...Thanks.
you may have to look up the diagrams on the terminals on the ECM to understand which terminals to jump. you should have the 22RE being a 91. connect terminals Te1 and E1 of the check connector. should be 5* BTDC @ idle.
disconnect check connector. should be at 10*-14* BTDC.
