Newbie here,
My 94 land cruiser is idling a little rough upon starting. Problem gets much more severe when accelerating. Hesitation and cutting out when attempting to accelerate, when returning back to idle the shake is fairly severe. I have to this point:
*Removed, cleaned and checked the EGR valve
*Checked the intake hose for leaks, all good
*Checked and replace as needed vacuum hoses
*Cleaned the connector on the O2 sensor closest to the outside of the body
Questions:
1) My next step was to do the same with the inside O2 sensor. But I found that the previous owner had replaced this sensor with a Bosch sensor. In doing so they cut off the factory connector and added the Bosch universal connector. I am going to order new O2 sensors x2. My question is what is the best way to handle the inside O2 connector since the original is gone? Splice or is it possible to order a new connector? Where can I find a wiring diagram for either the splice or new connector?
2) After I checked the EGR, intake hose, vacuum hoses, and cleaning 1 O2 connector upon starting it was still running rough. I then pulled the EFI fuse to reset the code and upon restarting the car ran perfectly. Does this make sense? I have little faith this will last and suspect that the issue will re-appear shortly?
Lastly, are NGK O2 sensors OK, or should I stick with Denso or Toyota? And am I on the right track or should I be looking at something else?
Thanks so much,
Mark
