So i adjusted the tps an now i can jump the connectors an it will idle down so i could adjust timing the right way an then when i unplugged it , it idled up and went to 10-11 so the timing is set now but it still bogs if i rev to fast or take off to fast but i can rev it an drive slowly and it runs wayyyyyy better
Any ideas now ?
New injectors should be here tomorrow and we will see what happens with them

VF1 is the conditioned (0-5v) O2 sensor signal, WHEN TE1 is jumpered to E1. Without the jumper, it is 5 voltage steps giving fuel trim (2.5v is "normal").
If you jumper VF1 to E1 (ground), you may damage the ECU. Do you mean you put a voltmeter (infinite resistance, definitely not a "jumper") between VF1 and ground? Did you have the TE1-E1 jumper in? Did you get the 6-8 flops in 10 seconds? That's the test for an O2 Sensor.
