Hesitation at startup

Does anybody get hesitation or misfire revving up after starting warm?? It only last for a for a few seconds then it's fine. I only have 1200 miles and no mods

Take the lack of responses as a big nope... What gas you putting in it?

I only use 93... this isn't my daily driver either, it's nothing bad really it only happens when it's warm and I start it and rev it up right away.... There's a slight misfire and it only lasts a few seconds, I'm hoping whenever I get around to tuning it, it will help this... My assumption is that the ecu takes a few seconds to kick in

this is normal behavior. i wouldn't rev it up right after starting it. supposedly not good for it. happens to most vehicles actually. the theory is is when you first start the car, the vehicle is kind of choking itself to start, using a lot of fuel (like the glory days with the manual choke). when you rev right after starting it it dumps fuel in and the engine chokes on all the excess fuel. you should be fine just give it a min before revving it

Ok cool I figured that's what it was... Obviously I never do that at cold start. But I was just curious whether anyone else experiences that. Since I just installed my new axlebacks I guess I just get a little excited, but just a little embarrassed showing off the new exhaust with that few second hesitation. Now I know to lay off the gas for a bit

yea let the dealership know if you can reproduce it... try resetting the battery its probably something simple since its so new.
