The engine may experience spark knock AKA ping or pre-ignition. Excessive pre-ignition can cause damage to engine if allowed to continue.

Can you use plus gas in a 1991 Chevy camaro iroc z28?

yes you can. the higher the octane "within reason" the less chance of you having spark knock. low octane fuel takes less pressure to detonate. so when you have a high compression engine with low octane fuel it detonates before the piston has reached top dead center. with low octane fuel it becomes unstable as the pressure inside the cyliner increases. you dont have to worry about going up in octane as long as it is unleaded. if you use a race fuel that is leaded it wont damage your engine but will more than likely burn up your o2 sensors. hope this helps.
