Main Engine Relay.... on 2005 Nissan Frontier

I have a 2005 Nissan Frontier SE w the 4.0L V6. Truck wouldn't start and when it would it would sputter at best, i ended up having to replace the main engine relay. Runs fine now but 2 days after replacing it then "service engine soon" light popped on and has been on for 2 more days now. Gonna get it checked out, didn't know if anyone can add onto this for me. Maybe it only needs to be reset? Thank you..

no, the light comes on for a reason. you need a real shop to do a real diag to see where the failure has occurred. get back to us with the code number and we can help more.

Ok i found out the code for my check engine light... P0430. Any help on this would be appreciated! Thanks..
that is a cat converter code. if it is clogged, it will not start. otherwise it is just worn out. a cranking vacuum test will tell if it is clogged.

Very much appreciate it!
