the engine light comes on and goes off only when the car is fully warmed up(or atleast thats what i think makes it come on)

when i got the thing jumped out and the light isnt on.. it turns off and stays off..

when the engine light is on and i turn it on to get codes.. the light just stays lit and doesnt do anything

anyone have any ideas?


when the light comes on it starts idleing rough (up and down between like 1000-and 1500rpm) maybe u guys for some ideas for me to try that arent alot of work.. i wanna try to get this fixed for tomorow so i can goto skool and all and not have to worry about it
