What could b causing my 1996 Toyota 4runner 2b just shutting off while driving? Pulled off highway 2 a rest stop and truck just shut off. Had 2b towed from there nobody seemed 2 figure it out yet. I drove home from vacation with it OK from it shutting off on me but then my check engine light came on ,pulled into auto zone and it showed a oxygen 2 sensor. They said that it would not make the vehicle just shut off. Help!
Possibly dirty/faulty idle air control valve or dirty throttle plate. Or also could be egr valve sticking open.
