Hey guys so heres my story. Got a 97 ex 4.0L OHV about a year ago and has been running ok except that I had the dreaded P0171 and P0174 until about 2 weekends ago. I have been doing regular fluid changes and general maintenance to keep her going and have done a complete brake change, spark plugs and wires, and intake plenum orings, upper intake manifold gasket, and valve cover gaskets a few weekends ago. During the gasket change I snapped the ECT sensor on the right side (the one going to the computer I think) but replaced it the next day. Now heres my problem. After I changed the gaskets, the 2 previous codes went away (YAY!!) but had code P0118 until I changed the sensor, now I have code P0117 and she runs like S**T at startup with a cold engine, when she is at operating temp she runs great?? I reset the battery and cleared all of the codes for about a day. Since then I have put almost 1000kms on her and am still getting P0117, I havent done a continuity check on the sensor but I assume its good because its brand new. The only other things I can think of are that the sensor is either not getting power, I messed up during the gasket change, a Vacuum leak, or IAC, MAF, EGR, or similar issue. Any suggestions would be great.
