Help! Car runs great at open loop, seems weaker at closed loop
I dont know what's going on with my LT1 but its running a bit odd.
When the engine is cold its nice and powerful. It breaks the tires loose pretty easily.
But the problem is when it heats up and gets to closed loop, it will lag in power and even on WOT from a stop it wont break loose. It just seems weaker when passing and general driving. It also seems to hesitate as well. But at idle however the exhaust smells a bit gassy and it doesn't seems to be as loud as it used to be. I also idles kinda rough
Maybe the coil is going south? opti? The opti is stock so any suggestions? Engine is stock
Thanks a bunch.

Check it for codes. Mine did this when my opti was going bad. It would run fine when cold once it heated up would miss and not run then it would throw a code and go into "Safety mode" and run fine again, until I cut the car off then it would do that everytime
