Check the Opti harness connectors for corrosion or damaged pins. Check the IC Module. Check the fuel pressure at WOT/max RPM/max load - while accelerating
.
A torn intake elbow can really screw things up, allowing air to bypass the MAF sensor. At WOT that will cause it to lean out. Such an obvious defect needs immediate attention.Fred
