LC 105 motor running rich.

Had new air filter and new sensor put in and had injectors for serviced

Hey yeah ive checked everything and ive replaced what needed to be done. The mod i saw was on this forum from a few years back not sure who it was that did it. My cruiser dont have an oxygen sensor on the exhaust as it has no cat

A petrol engine not having a cat doesn't mean it doesn't have an oxy sensor. An oxy sensor keeps the mixture more correct than the airflow sensor can. It sounds like someone has bastardized your system. You say you have checked everything? Really. You would be amazed at things normal mechanics miss. Just trying to change components is one way ti fix it. Just means everything is replaced until it work well. Have a decent check of items people mention.
If mechanics have done work on the vehicle for this reason and you have checked "everything" , either they didn't find the fault and your checking everything is deficient, otherwise the problem would be solved. If you have the capability and understanding of the vehicle systems then you wouldn't need to ask.
Replacing an airflow meter may may be just a stab in the dark.

Seriously dude wats your problem i do all work myself and yes ive gone thru everything on my car and replaced anything that looked like it needec replacing. Ive askedon here to see if anyone had same problem . The car hasnt been bastardized its never had a oxygen sensor even my other 105 didnt have one. Ive checked everything again so if your going to just have a go at me then dont bother messaging back. Its guys like u that alot of people wont ask for help as they get told off by people like u. And yes i know wat im doing as ive built alot of cars and motors myself. Plz dont msg my post again as i dont need to hear from you again.

I see the limit of tolerance or understanding has been reached. If you have done "everything" to the vehicle and have the skills, then please tell me why it is running rich and you haven't found out why. You MUST realize, I and others are remotely providing replies based on what information is provided by YOU or can be gleaned from what you mention. Just saying everything has been done, means to me there cannot be any problem anymore. Just REPLACING stuff may fix the issue, but it appears the ability to diagnose anything is missing. Sorry can't assist further.

Yeah no worries. Ive ended up solving my problem anyways.

As a nosy bystander, what was the cause?

One of the new fuel injectors that was installed was faulty causing it to run rich.
