    Hey guys,
    I have a 90 sho mtx (was wrecked). I have some issues that I'm working on to make my sho safer for the road. I can drive it but, would like to start getting these things fixed up.
    First, some codes I pulled:

    *KOEO: 11, 11, =all ok?? then 6791, 6791 = what is this??

    *KOER: a single 3 code?(not fast flasher,regular)
    then, 91, 91 =HEGO (bad O2 ??)
    ~Best price for O2 sensors and where?

    *Balance = 9, 9 (all ok ??)

    *Airbag light 6,6,6... does this say which sensor is out/bad? I have all parts to fix it now,but just need to locate bad sensors. Anyone know locatin of all sensors? Can they be reset and reused(not likely, right)??

    *Antilock light on constant(old problem). Left front suspension(all) was replaced because of wreck. Antilock light did not come on for about the first two months, then intermediate, then constant. How do you test or adjust sensor at wheel? Can I simply replace/swap the computer thingy(beside airbox?) with another for troubleshooting or is that problematic in itself ??

    Thanks for any help and info in advance. :)

    *Side note* I paid almost $200 buck on three different alignments with no avail. I did my own 4 wheel alignment with basic stuff (tape measure, long 2x4, my eyeballs) and got better results... go figure :confused: !

    Hey there. The 11-11 means everything is ok. The 6791 is a stored code from when the engine was running and it is probably 67 and 91, which according to haynes are:67, nuetral drive switch open and 91, oxygen sensor indicates system lean left side. The manual with my code scanner is at the shop so I can't really help with the others right now.
    My 90 mtx has three airbag sensors that I know of. One is mounted underneath the fan cover with the veci label. It is a small black box and the label should have an arrow that tells which way is forward. The other two are mounted on the sheetmetal behind the front bumper near the bumper mounts. Hope this helps.

    The descriptions of the codes are as follows.

    67 (M) Intermittent Park Neutral Position (PNP) sensor fault - PNP. Did you move the shifter during the test?

    91 (R, M) LEFT OR FRONT SENSOR System running lean - Fuel control. The front bank sensor has given up the ghost. Get the Bosch 13942 from AutoZone or AutoZone.com for $33.99+tax.

    The 3 code means you have a 6 cylinder engine (3 spark events per revolution).

    The 6 airbag light means you need to search on the post I wrote to fix the clockspring continuity fault in the steering wheel.

    Sounds like something is still bent in your front suspension.

    Thanks guys for the info. I don't recall bumping the stick during the test... I run the codes again tomorrow afternoon after I get the new O2 sensor in place. Scott, I saw that post you spoke of and will be on that in a few days. Thanks again! :)
