Live Data Reading 2001 Excursion - Any thoughts
Vehicle 2001 Excursion 204000 miles, 6.8..no codes but seems to be running rich(smell fuel from time to time and once in awhile is lopes like it’s loaded up with fuel). Here’s live data from Matco Scan Tool. Any thoughts?
FUEL SYS 1 CL
Fuel SYS 2 NA
calc Load % 48.2
ECT 158(yes, done after driving 5-6 miles)
STFT B1 0.0
LTFT B1 16.4
STFT B2 -3.1
LTFT B2 19.5
RPM 821
Speed 0(sitting in park in driveway)
Spark ADV 17.5
IAT 37(should be correct as outside air temp was in the teens)
MAF 1.1
TPS 20
O2 B1 S1 .615(fluctuate between 0.01-.90)
STFT B1 S1 -4.7
O2 B1 S2 0.00
STFT B1 S2 99.2
Ive pulled live data a few times, LTFT B2 always seems a tad higher than B1. Not sure if this means a faulty plug or COP on bank 2 or not.
runs great, plenty of power, gets 12-13 cruising at 75-80 unladen, so can’t complain too much.
Thzbks in advance.

Agreed, 158 is pretty low after 5-6 miles.

That was a thought. It gets to operating temp rather quickly, less than 2 miles, but the gauge has read just below the icon since we bought it once warmed up. So there are two options for that, either the thermostat was replaced with a low range, 165 maybe, or the ECT sensor is faulty. Probably best to replace thermostat with a new one that I know is correct range and if it still appears cold from gauge replace ECT sensor.

In any event, replace it with a new one of the correct temperature range and then re-evaluate.

So some fool put a 165 thermostat in it. Just replaced with a 195, ECT reading 194, LTFT B1 3.1, LTFT B2 4.7. Idle steady about 800 in park.
I’m assuming a need to change plugs, running cold for who knows how long probably took its toll on them.
is that variation of 1.6% on LTFT normal?

Thanks for this thread. Got me thinking about my thermostat. Decided to replace mine and it was way over due. I could immediately see the temp gauge climbing much faster then when the old one was in. The indicator is also a little higher on the gauge. All I have is an analog gauge so Im just guessing maybe 20 degrees or so higher. Someone said something about the A/F ratio being richer in the colder temps so Im hoping to gain a little fuel mileage and also heat the cab a little faster in the mornings.

So now looking for spark plug recommendations. The truck has 206k on it, so I want to change them if needed. I’d rather go buy the plugs and if I don’t need them I’ll return them then to pull them all to see if they need it. Bosch, NGK, or Autolite Iridium?? Any other brands?
The next question, and I did this on my 1999 5.4 F250, anybody recommend or say not to use a little copper anti seize on the threads?
