a few service codes

[jordieb213]

let's see....the rover idles a little funny when sitting in gear...also, i used an OBD II scanner and got these little numbers.

P1668
154
174
1174

it said something about an 'ion actuator'...it smells like it is burning a little rich as well, and i just got back from a road trip which consisted of all but 20 miles of highway travelling, and i only averaged 12.26 miles per gallon....thats horrid...i usually get better than that when i am just driving back and forth to work through the city!!!....ave. speed on the highway was 70-75 mph...if you guys have any thoughts or information, let me know...

wow...thank you. that was a great source of info!!!

umm..... bank 2 is the drivers side or passengers side on the disco II ??

ps....P0154 O2 sensor circuit, no activity detected bank 2, sensor 1
P0174 system too lean, bank 2.

Bank 2 is the pass. side. How many miles on your truck, what gas are you running?

i've got 100,500 miles on my 2001 SE7, and i only use 93 octane.

[Disco Mike]

Well you are at that place and mileage where O2's don't work like new and the power, MPG and torque go away. If you go for O2 replacement do all of them after a good engine flush and decarbon. She will run so much better.
Have you replaced your plug wires, if not they are not doing you any good either.

yes sir, i have got new spark plug wires on there. so by ALL o2 sensors, you mean, before and after catalytic converter on both sides...and also i need to grab a new set of spark plugs. what plugs do you recommend? i'm running 10w-30 mobil one fully synthetic with a K&N 3001 long filter..(okay maybe 10w-40 because it was summertime, not sure). but i'll just go ahead and change the plugs and the sensors.

someone should give you a raise!!!! you're great help, and it is much appreciated.

I run 20/50 Castrol blend in mine along with a 3001
What brand of plug wire are you running?
You might check these sites for prices,
Rover Connection
DAP
for O2sensors, they are pretty good on their prices. With the right plug wires, Bosh Platium Plus 4's.

i'll try your oil choice for the next cycle...i just changed it about two weeks ago.

i changed just the bad 02 sensor for now, what a difference already....i'll get the other three after i save up some more money(i'm a college student, and the classes aren't free), i'll just go ahead and change out the plugs, the wires, and the sensors at the same time...give it a nice tune up. for christmas i'm hoping for a lift...is the 3" OME too high??
