So i just gone done changing my oil
i disconnected some sensor thats between the supercharger and the motor then connected it again and i reseted my oil life
and when i turn on the car the check engine light is on?
does anyone know what this could be or how i could take the check engine light off?

 

disconnect the battery.. it will reset the ecu.

 

So when i disconnect it itll take the check engine light away?
and notin else wud appear?

 

the barometric pressure sensor. did you plug it in all the way when you put it back on? happened to me when i forgot to plug it in. reset it and it should be fine.

 

yea i turned on the car and forgot to plug it in
then u plugged it in but its still there
imma jus do dat reset the battery
thx guys

 

I may be way off base but is it a good idea to disconnect the battery with a tune?

 

its perfectly fine.. just resets CELs and fuel trims

 

yea its fine

 

I'm just going off what I've been told "it's not a good idea" just what I've been told

 

really? did they tell u wat happens if i do reset it? cuz i havent reseted it before

 

put it this way. if you change the battery on a car, does it erase the ECU? I've heard of putting a battery on in the wrong order and it frying the ECU, but your just disconnecting the Negative side for a few seconds.

 

it could possibly lose the tune and or mess up the trims, but I my self haven't done it on a cobalt but have seen it happen on F-body's

 

so if i jus disconnect the negative side and leave the positive side on for few seconds ill b fine?

 

yea. you'll be just fine dont worry bout it

 

thx

by the way is it bad if i put 7 quarts of mobil 1 in my car?

 

better to have to much then to little. i use to put 7 quarts in, thats when i thought it took 7 quarts though. anyways my car ran fine.

 

I would only put 6 in I would not put 7 manly because if you over fill your car and when it start to build up crank pressure it send oil through the intake there for going through the super charger and causing white smoke to come out the exhaust

 

aww *** i accidentaly put 7
****

 

Too much oil is just as bad as too little.

disconnecting your battery will NOT do a damn thing to your tune or ECU.
