What order to install cells

Checked voltages all at or right at 8volts did a load test all passed put it back in and drove 100 miles and triangle of death came in with the different voltage something something . Took it back out and doing a one cycle charge to get mAh . Some are 2000 something most hight 3 to 8000 something . My question is I will change out all 2000 mAh something , with this done what order do I install the cells from PC side high to low or I even herd middle going high to low going left to right .

 

I'm new to this and trying to learn , I load tested with a 12 volt electric motor . I tested voltage before applying load and as load was applied . If say it was an 8 volt at test and when load was applied it did a drop to 5 or 6 volts then I tossed the cell . Instead of discharging charging three times I just did it once to see where I stand on the cells . So some are at say 2456mAh and others are st 5678mAh to 7890mAh I would guess the 2456mAh cell is bad causing the code to come in after a period of driving as the battery would not hold a charge as long ?

 

I have yet to buy techstream on the low there is like three that are say 2345mAh and around the same at say three at 3456mAh and the rest are 4567mAh to 7890mAh . If I get cells all from say 4567mAh to 7899mAh would that be ok and how would I place them in the pack . Thank you

 

I did but I was stupid and was placing them on eBay and selling them , I guess I have about 12 left and without having tested them I'd bet at least half are bad . Lol looks like I'm deep enough into it at this point that I will be back on eBay buying some back . I love the car and when it runs right it's a great little gas saver .
