cammed but not cammed lol

[GBB02]

so i’m thinking i’m off timing a tooth or so i replaced my timing belt and it starts up fine no issues but once it starts to idle it chops like it’s cammed. i’m replacing my downstream 02 sensor since mines broke so i’m throwing a code for that and my heat rises a little bit and it’s never done it before unless i go above 80mph and i’ve heard being off time can cause it to slowly rise. someone let me know what the issue is please

Why not check your timing?

it going to, i was just wanting to see if there’s any other thing before i have to. valve timing is good but i’m pretty sure it’s crack timing off a tad

I would do that first, then fix your CEL, before doing anything else.
