heres the deal... driving home and notice a reasonable loss in power. id give the disco more gas and still no power down shift still no power so i pulled off the road and sure enough my check engine light came on as soon as i stop.

the code display is showing code 45, which is "Lambda sensor B - right bank"

i looked at all the connections real quick and didn't notice anything wrong....

so i let the disco cool off for about 10 mins. and then hit the road.... the disco drove the rest of the way home just fine like nothing was wrong at all.

does anyone have any imput on this or dealt with this could it be bad o2 sensors?

'95 disco v8i 154K miles

 

Well, with your mileage, those 02's are basicly fried, start with some new ones and go from there.

 

ah figured just curious as to why the problem was so intermittent. has never been a problem before. ill order some o2 sensors and see what happens. are there cheaper o2 sensors out there other than the oem land rover ones?

 

I wouldn't reccomend off brand sensors. I've heard stories of people having a lot of problems with the cheap stuff. Most of the cheap ones just come with a wire and not a connector which is all well and good if you can wire it together and heat treat it real well. I've never tried but like I said I've heard of too many failing.

 

Especally when it comes to D1's don't go cheap. get you vin number and go to Rover Connection, check their 02 information, depending on your vin and emsiison system there are a couple different ones to pick from and only one will work on your truck.i

 

just purchased from brit pac hopefully this fixes it

 

ok so driving home today still waiting on o2 sensors the disco all the sudden started back firing and lost most all power pulled off road let cool down and 30 mins later drove home fine....

got home o2 sensors were in so i threw em in ... changed air filter and cleaned MAF real quick

here are a few things ive noticed and now i have a new problem!!!

first is i had my idle set at around 800rpm with the old o2 sensors when i changed em out and fired the truck up it was like at 2300 rpm and didnt go back down so i reset the idle and all was fine drove around and it was awesome......

went into walmart and came back out and it started up and was barley idling sounds liek no fuel.... let it warm up and drives fine kill the motor and start again ... same thing...



any help please??!! im lost right now gonna try resetting the fault codes stil reading code 45 again

 

now cleared code 45 and it has code 19- Throttle potentiometer input low/airflow meter highUsually indicates a problem with one of the two mentioned parts. Refer to tests 17, 18, and 19 of the continuity test procedure.


could it be when i cleaned the maf????

i used electronic cleaner

 

update...
drove around for awhile after clearing codes and nothing else has come up feels like it has way better throttle response and hasn't done any wierd sputtering stalling it was doing at initial start up...

praying i didnt kill the maf!!!!!
dint really spray the maf mostly just throttle body and pvc tubing...

some crc electrical cleaner might have gotten in the maf though?

long drive to la tomorrow hope all goes well....


need to save my money to build my half-rack and buy two true track's not maf's and sensors...

 

Looks like you might be good, hope all goes well with that
