I have a 2002 rodeo that will almost die when starts up then pick up and go to 2000 rpm then drop down to 1000 rpms . It will do that every time you start it up . I would like to know is the electronic throttle and the foot pedal sensors going out? I is not throwing any codes but once in awhile the service engine light will flash . But will not flash when I have my scanner connected
Please help
