security light
 

so i replaced my fuel injectors 1st time in 250k. also did the valve cover gaskets and the upper plenum gasket cause i was having high idle issues. i would spray carb cleaner in certain locations and the idle would change. thats how i found a gasket change was warranted. so its all back together and running great again. but after the rebuild the security light is staying on. i cant figure out why. any ideas? car still starts though...its a 94 3.4L.

could just need to clear it with a code reader,these cars can develop quirks that are just
a mystery sometimes,like my 99 caddy saying it 140 f outside ,an runs fine, computers ,older cars high miles ,they do that sometimes
