Hi Leon,
I have gotten code E23 before on these engines due to the throttle body control wires rubbing through and shorting on the housing. Unplug the control pigtail from the throttle body and examine it very closely. Repair all damaged wires/insulation, then give the pigtail a twist before reconnecting it. This will shorten the pigtail and keep it from rubbing on the housing. Good Luck
