Question about 1999 Isuzu Rodeo
HI GUY´S I HAVE A 99 RODEO 4X4 AND HAVE PROBLEM WITH THE ECM, WHEN THE MOTORS IS RUNING SOMETIMES FEEL LIKE THE FUEL IS CUTTING AND I NEED TO PRESS ALL THE ACCELERATOR TO CONTINUES RUNING
That can happen for several reasons the least being the ecm. first thing is it could be a weak fuel pumpand the only way to check this is with a fuel pressure gauge. it should be between 17 and 25 psi. next it could be the TPS(throttle position sensor) this controls your idle. this is located on the throttle body has a weatherproof plug and is held with (2) screws . next is the engine speed sensor this helps the ecm adjust the fuel/air mixture in conjunction with the TPS,IAC valve,O2 sensor<and the egr valve. to pinpoint the sensor problem you have to have a diagnostic scan done. please rate this.......thanks
