2002 4.0L idle issue
Hey guys,
So I have a 2002 ford ranger and its not liking to run right aparently. When first started it will idle ok then after about five minutes the idle will drop and bounce between 500 and 800 rpms. It also has an issue with wanting to spike in rpms between shifting gears (its a 5speed man.) If I turn on my fan (doesn't even need to be ac) it will jump about 150 tp 200 rpms then die back down. Codes were thrrown leading me to o2 sensors which I replaced but that didn't fix. I also had a new maf sensor at home I put in but it did nothing. Pulled the neg cable off everytime I changed a part and I have been told I need to reprogram my ecu? Anyone think it might be the iac or the tps? Thoughts? Thanks guys
