(94 4runner v6).. jumpered t1 and e1 and got a code 12 (knock control sensor signal/rpm signal)... could this be a symptom of why i have lack of power and poor mileage. afterall, i've already tried narrowing down my first to do list,.. blew the gaskets earlier this year and had everything rebuilt. spark plugs and wires, dist. cap n rotor, fuel filter, fuel pump, vacuum leaks, compression, timing, injectors, seafoam, cat, o2 sensor,.. all changed. oops, i overlooked changing the knock sensor pigtail when doing the headgaskets. does this mean i have to do the timing all over again after i change it out?...
