Poor idle,stalling,vsc,traction control, any tundra.

Ok ,vsc,traction control lights,stalling poor idle, no 5,6 gear. First got new gas ⛽ cap after 14 years not sealing properly, now when I fuel up, I hear vacuum breaking from tank. Before truck would stall every other traffic light, after new cap ,no stall,but very low idle 250 rpm.
2. Second thing I did was clean throttle body ,checked very dirty, cleaned in place no removal, used rags wet with throttle cleaner, must work it in there to remove black soot ring on body!!,after cleaning, cleaned mass air flow sensor and reassemble, new air filter, keep in mind my original air filter was 14 years old, because I blew it out with compressed air, worked well for me and saved lots of money . I have the old spare to clean and low out.
Disconnected battery negative for 5 minutes, erase codes,restarted
Wala, idle up to 750,no lights, test drove no stall,5,6 gear awesome running like a top ,did get new double iridium plugs to install in am as mine are 100k old .
I hope this helps anyone with stalling low rpm ,poor performance, and below 500 rpm alternator won't charge. So hope this update helps.
