99.9999% of the time, the ecu is fine (man handled or not) when the car will even fire. They just make good scape goats for people that dont know wtf they are doing.
Meanwhile the MAF is the most important sensor, and can cause exactly what you are describing. Clean the maf connection, and check for post maf air leaks.
And quit smoking so much weed so maybe you can think straight and actually fix your car.
