I have already changed the fuel filter and it didnt make any difference. I'll check the regulator. After that i dont know. Im out of ideas. Maybe have to break down and take it in to the dealer. The engine sounds alot different after doing the intake and 02 sensors. I think it sounds like it is idling too high but i dont know anyone close by with a rodeo to compare it too. Thanks for the help. <img src="/forums/images/graemlins/cheers.gif" alt="" />
