said by Doctor Olds:No power could be clogged exhaust/converter and or clogged fuel filter/bad fuel pump. You still have some diagnostics ahead of you unless you drive it to a Dealer or a shop.
Managed to drive it Autozone, they said I should take it to the dealer to get scanned.
They pulled stored codes:
P1031 - A/F Sensor 1 heater control circuit low
P0725 - Engine Speed signal circuit
But they might have been from me unplugging sensors.
Someone mentioned it sounds like it is running in 'Limp Mode' and I should try to reset/clear the ecu.
