i have a 1994 k1500 4.3 5 speed. it will idile fine but if u drive it for 2 mins or so it will start to miss fire and run like ****. i have checked the noods and replaced the pcm box not the chip and also so have checked the timing and replaced the disturber 3 times. there are no codes flashing when u self test it but 12 and 13. these are code for self test and no o2 Sensor. oh i forgot to add this if u drive it and it starts to do this turning the key off then on will make it drive fine for a few then it will start to do it again. i have no idea what this things deal is any one ran in to this before?
