So far I replaced cam shaft position sensor, crank position sensor, maf sensor, o2 sensor, throttle position sensor. Now the mechanic says it might be the computer$$$ all original miles on the motor too. Cap and rotor are new spark plugs and wires also? Help me please

Do you

You have to hook up a back pressure tester to the exhaust you screw into where the front o2 sensor goes. Then you start the engine and raise the rpms up to 2500 and see what it reads?You would test it when its acting up I would just take it to a exhaust and have them test it.
