3vz failing smog no ac and code 51.
when i have the diagnostic connectors jumped and truck is idling it rapidly blinks like normal, however if i give it gas it gives me a code 51 and as soon as it is back at idl it goes away. tested the idl and e2 connectors on the tps and they are working. hoping that its the problen with the smog or the ac

You don't check for codes with the engine running. Key ON after TE1 & E1 jumped.
Colde 51, IIRC is knock sensor. That would put your timing at 0 degrees BTDC.
