Misfiring bad

[stroller]

2000 LR Dis 2 w/143000 miles has misfire codes on all cylinders, o2 sensor B2S1 code (?) TC,decent light and ABS light on. Runs really bad but if you lock the breaks as if in a panic stop it will run good for 20-30 miles TKS

When was the last full tune up and what did you do?

TC, HDC, ABS are normally one of three things, but Dirty sensors are near the top of the list.

We need all the exact fault code 4 digit numbers to be able to help.

codes

When we had id put on the machine it had 39 codes however alot were dupicates.
0300,0301,0302,0303,0304,0305,0306,0307,0308,1300,0150

permanent voltage fault
autotheft alarm serial link fault
battery voltage not plausible
cataylist misfire
misfire with low/empty fuel
emisson revevent misfire
low range signal implausable
oxy sensor heateo down strean cat b2
(62,65,4,0) refer to tech manual

the only thing that has been down tune up wise is plugs and wires

Tks for your time

 

[Disco Mike]

So, how many miles on this, has it been tune along with wires? If you clear the codes what shows up again, the reason I am asking, it is near impossible to have all 8 cylinders misfiring. By the way, what octane gas are you using?

 

[stroller]

codes

cleared all the codes and wk later they were back after probably 30 miles. 20 miles 0n wires and plugs. 93 octane. does make any cence that you can do a really hard panic stop and it will run almost good for 30 miles

Tks again
