My 97 Ram 1500 is giving me a check engine code 27 when I do the ignition test procedure. According to the Haynes manual it is: "One of the injector control circuit output drivers does not respond properly to the control signal. Check the circuits." This makes some sence becasue it bogs down while accelerating. Can anyone give me some advise on this...thanks

 

pull the plugs and smell which one is gas fouled or you can take an ohm meter and check the injector coil resistance. if all are good, then check the wiring.
