Did you adjust base timing with the engine idling after warmup? That has to be at 20 deg @~800rpm before diagnosing anything else.
Also, make sure your TPS is around 0.45-0.5V when throttle is closed, coolant sensor voltage is good, and MAF is good and that they are all reading the right values.
All those can cause the ecu to add/remove timing.
