5.7L V8 engine K blazer. Anyway, on cold start, engine will give the odd sputter. Upon putting it in gear after warming up a few minutes, it sputters badly when trying to accelerate where it seems like it wants to stall.
Once engine is fully warm, it seems to operate completely fine.
First time brought in, no codes given, but spark plugs cleaned and fuel injector cleaner put in. Ran fine for about 3 weeks then sputtering started again.
Brought it in again, and cat converter changed. Performance better but again, after 3 weeks the sputtering issue is back.
Any suggestions? Thanks

Any codes? Check and clean EGR. If there is an IAC, remove and clean it.
