my 91 isuzu trooper doesnt want to go when i push the gas and has no power when it does go the codes that come up are 24 vechicle speed sensor (vss) circuit - V6 models i found that my speedometer cable was broken and got a new one but it still comes on and the other code that comes up is 44 O2S lean / fuel metering {9} but i have replaced the O2S two times now and it still comes on
please explain..when you say it wont go when you give it gas,,,does the engine rev up but not pull the suv?or,,does the engine not rev and feel weak?
tell me all you can

the revs but feels week like its not getting gas and when you push the gas it stutters then kind of starts to go
Customer: replied 3 years ago.
it revs up to 20 then has troble gettting higher to shift and you have to let off the gas for it to shift and when it shifts it kind of jerks
you need to check a few things here.
1-check the fuel pressure,,the fuel pump may be weak causing low fuel pressure,or a clogged fuel filter,this would also give you the 42 lean code
2-a bad throttle position sensor [tps] could also do this,,most times if this is the problem,,you will get a code for it
