[sold my malibu]

now I can't figure this but :
we have a afm (by code 24-31) giving me intermitant trouble.somrtimes fine then not so good at idle.OK at highway speeds

incorrectly clean it (lets not go again)then just horrible.
pull it apart seal it up and good that day,next day start-up fine then 10 minutes later ,up to temperature and back to the way it was before I touched it.
basically I know I need anew one at this point.
I checked into the maf-pro route ..ya not quite ready for the big time just yet.
I think I will go with the lexus upgrade ..MAF ,550 low impedience injectors and pump.
The thing is guys is:Can some one tell me why the AFM in the lexus won't work because some people say it does.
If its job is to read and tranmitt info to the tccs how can the tccs eff it up if I have the rest covered (550s and higher volume fuel pump)
