Since you have done a major tune up,and having a problem like this,sounds like the timing needs set,or the distributor has a small crack in it.

Misfiring on 2 & 7

Hate to say it but I would look at the valves on those cylinders. I would venture they are not sealing properly.

Good luck.

Do you have the 3.4 or 3.8? If its the 3.4, they had issues with the fuel pressure regulators getting funky. I had to replace one on mine twice before the car had 150K.

My chrysler cirrus 2000 model is not starting, a mechanic said the brain box is bad, we have tried over 7 other brain box without any luck, what can i do to get the car working?

It seems that if you tried that many brain boxes, one of them would have worked.

Here are some things to check. (I am assuming you have gas in the tank, the battery is good and the engine cranks over but doesn't catch and run.) Perhaps one of these items was overlooked in the trouble-shooting:
Engine cranks but won't start:
Charcoal canister full of fuel, faulty MAP or MAF sensor, faulty engine coolant temp sensor, faulty EVAP canister vent valve, EGR valve stuck open, lack of or incorrect fuel pressure (fuel filter, fuel pump, fuel pump relay), water in fuel, fouled spark plugs, faulty ignition module, severe vacuum leak, severely clogged fuel injectors, wrong size o-rings on fuel injectors (prevents compression), faulty airflow sensor (if equipped), Idle Air Control (IAC) valve defective, disconnected-broken-loose wires for all of the above.

You need spark plugs,and wires(or boots) and fuel filter,and air filter,and a pcv valve wouldn`t hurt either.
