Default Random blinking check engine light

I did a cam swap about a month ago, its been on base tune waiting for my dyno appointment at vengeance racing. I have driven it maybe a hand full of times babying it and testing the upgrades with no issues. Not doing wot or anything and keeping rpms low, like nothing over 4krpm. So car has been running great till last night. I drove for about an hr no issues. then random cel light would just flicker so quick i barely noticed it. it done this a few times in 15 minutes completely random. Now seems to do it more frequently but still random. sometimes after flickering cel light stays on for like a second or 2 then goes out. It idles fine when i start even to temp no cel light. can drive maybe a few minutes. then slowly flickers happen but like a split second, as i get to 2nd or 3rd gear happens more an more frequently, when i push in the clutch they stop completely. shift and give it some load then flickers like crazy consistently, so i immediately pull over turn her off, let car sit for a couple of minutes. start again. idles fine no check light whats so ever, it can sit all day idle no cel. So again warm to temp, no cel, drive 2 or 3 minutes then same thing again. after this happens smells like gas, so like its unburnt or something. Coils seem to be connected fine (they are stock though, with the amount of upgrades im thinking i need to upgrade), all my grounds attached. Only thing i can think of is the gas has been sitting in the tank with fuel line on the engine open for a few months. Maybe fuel is starting to go bad? thanks ahead of time

upgradres:
tsp cam vvt-3 headers and cam
borla exhaust
rotofab
springs/7.850 pushrods

Cam and no tune? Not a good thing and could mess stuff up in the engine. If you have other transportation, I'd use it and get the car to the tuner before something disastrous happens.

Mike at vengeance tuned it for me. I gave him my computer and he installed the base tune. So it does have a tune. i been driving it lightly. I do have another car but due to girlfriend car issues. I was forced to use the camaro for the day. It been driving fine and no check engine lights before today.
