i got on it in the parking lot at work n went to get on the road but the engine suddenly started running like a 1940s john deere. as in it sounded like it was running on 2 cylinders and was runnin like pure ****. should i be concerned? im tempted to sell my car even tho i have a passion for it. its a 2008 ss/tc with a canned tune from zzp n only intake exhaust and 3 bar map's for mods :/ lmk what u think idk if its just i went hard on it to early after startup or if its something bigger. no engine light or flashing engine light wen it ran like **** but yea im worried cuz i just finished paying it off not even 4 days ago

I will save you the lecture about being smart and warming up the engine properly before getting on it. Could be all kinds of things-bad piston, broken rocker arms, etc. is it still running poorly now?
Personally I wouldn't sell it because it's not right for you to pass on a potentially hurt motor that you did by not thinking, to Simone else. Compression test it, and pull the valve cover and see if you have any rockers damaged.

it only ran like that for about 10 seconds n ran fine afterwards. u still think i should take valve cover off?

Its not hard to do. If you are worried about it enough to make a post, then you should.

Pull Valve cover, leak down/compression test, ditch the canned tune

If you floored it while it was still cold, I'd guess you blew out the spark. I've done that several times and most times led to the engine just stalling out. Stop doing that.
