2008 Cobalt Ss/tc Not Running Right

2008 Chevy cobalt ss turbo sounds like it has a lope tune at idle, it drives but has absolutely no power, it doesn’t build boost, and it seems to have a rev limiter at 4K. When I hit 4K the person behind me said it started to smoke and said they could smell gas. Also the ABS, TPMS, and Traction Contol light are on and it displays service abs, service traction control, service ESC, and ESC off.
Would that cause it to go into any kind of limp mode or reduced power?

Any help would be appreciated!
