Motor pings like a mofo under load in 100+ degree weather on 89 octane fuel...I replaced the upper o2 sensor, plugs, wires, cap, rotor, etc. No codes from the ECU, so I'm thinking the lower o2 sensor may be ok.
I'm thinking about filling up on 91 octane next time I'm at the pump...I was doing some reading and someone was talking about also going with a 180 T-Stat? Not sure if that would help or not...I may have to also invest in a timing light and make sure the timing is good like you said.
