Cars sounds weird. Help ASAP

Started my car, I’m running a cary Jordan custom 93 tune. My car idles okay but after it starts too drop rpms it makes it sound like I’m cammed. Any ideas?

Last time you did spark plugs?

Codes?

I'd go back to Cary Jordan. Even with old plugs, etc, I don't see how that would be effecting idle.

Codes would help though....

NGK 2 Step Colder Sparkplugs. I ended up putting in a precision racewerks stage 2.5 LPFP, Port injection with 750cc injectors. 3.5 Bar tmap sensor. Did this about a week ago or so.

Sounds like you did a bunch of work and then the issue started. I would double check your work as it all pertains to fueling and that's what you said your codes are pointing at. Usually supplying the exact code read outs is more helpful as well. There are a lot of codes that point to a lean condition. Some have to do with spark, some have to do with injection, some have to do with pumps, etc.

This right here, can damn near guarantee something wasn't done right. I'd check all those areas multiple times over. All proper procedures were followed. I'd bet money the code isn't a coincidence. Relates to one of the installs. Good luck OP

My guess is your port injection. If you get a slug of fuel through the engine, it will dial back everything to lean it out.
