KA Problems need help.

My 240 like idles fine then when you get on it it hesitates around 1000 - 3000 rpm's then it runs really good from around 4000 to 7000. I saw my O2 sensor wasn't wired up. Do you know what it could maybe be? I've tried to look stuff up and everyone says fuel pump, O2 sensor, timing or the MAF.

Also my clutch is slowly starting to slip but I don't think that would have anything to do with it. Anyone have a solution? It would be appreciated, Thanks!!!

Remove your passenger kick panel and check ECU codes.

I would fix your O2 sensor if you know it's not installed correctly. Try some MAF cleaner as well. Report back when known issues are repaired. Sounds like partial throttle causes the issues, perhaps it could be a vacuum line leak or bad throttle position sensor as well.

In terms of how many rpmss suited fourth gear atleast so those few extra fuel sumps determine about 10 gallons above empty before guessing any traction for clutch and then air emitt
