You may be right but I think you will find out differently when you replace the tps and calibrate it to the ecm. If I understand this right,you have not yet replaced the TPS? Yes ,fiddling with the accel enrichment and such can mask a faulty,glitchy or improperly calibrated TPS but when replaced ,all the changes you made before replacing the TPS will likely need to be done over.
As a side note,there can be no air leaks in the exhaust either. Even extremely small air leaks create havoc with O2 sensors. The old saying,garbage in =garbage out really applies to EFI.
