Would a 97 2.3 5 spd. man. have a knock sensor? If so where is it located? More for future reference than anything else. Also, cam position sensor. Would be atop driven shaft where distributor used to be? Was under truck today checking some things and saw no shaft, or is it behind PS/AC...

Have a 97 ranger 2.3 w/62k orig. miles. Problem I'm having is an intermittent stumble/cutout. W/KOEO the engine light will flicker and can hear IAC and relays cycle as if eec is losing power. Radio,gauges stay steady. Found pin out diagram and looked to be 2 ign. feeds, 1 mem +, and 6 grounds...
