My 2003 Nissan Altima sputters while its in drive. Sensors were changed. What ? on 2003 Nissan Altima

I've changed the timing chain, throttle body,cam and crank shaft sensors,catalyc converter, gave it a tune up. I am very stressed about this. I don't want to get rid of the vehicle I've put to much money into it.what should I do? Also my check engine light is on. It reads TCM and crank shaft sensor.
