Vince, can you water it down for me? I sit in a cubicle and do debits and credits in a banking system.
What do you mean "fuel trims?"

Can't hurt. After all that's where the pcm realizes if you're lean or rich.Hi Vince,
I'll get this exhaust buttoned up as soon as the dang headers arrive (downside of ebay sellers, they don't ship as fast). Do you think it's worth putting on a new HEGO sensor while it's all apart?

f your truck cam into my bay, fuel trims are the first thing ] look at. sft (short fuel trim) is the adjustment that the pcm makes fir immediate "repairs" LFT is the adjustment made for larger problems.
AH, yes, EEC4, gotta love it. Without extremely spendy equipment, you can't get into the data stream.Note: computer is from a 1995 F150, so it's not an OBD II system.
