ok redo this
basically i noticed the engine maintence light on this morning
my mileage is 3600 so i was thinking this came on as a reminder to get maintence done/oil change
checked the oil life and it is at 60%

yesterday i had installed a hks axleback went smooth
other than that i have no clue why it went off, im about to go to autozone and get it checked

 

there should not be any lights going on based on mileage and oil life.

the rest i cant help you with. good luck.

 

really i have that engine light on and i dont know why

 

Is it the Check engine light or the service due light? the service due light is the wrench. If its the CEL, then I'd obviously suspect that its whatever mod you did.

 

alright i just got back from autozone they said the code is P0171
Fuel system too lean bank 1 (cylinder number 1 denotes bank 1)
1 - large vaccum leak
2 - Fuel system concern
3 - Ignition system concern
4 - MAF sensor faulty
5 - H02S/AF ratio sensor fault

I have a prm intake installed in december and hks exhaust which i put in yesterday around 1pm just this morning this light came on when i was on the highway.

its the check engine light

 

bump any clue? faulty maf maybe but how?

 

yeah... not maintenance light, but a check engine light.

you prob hooked something up improperly. check all lines you touched when you disconnected them.

 

This would be my first thought. Second would be that your MAF sensor got fouled from the intake.

 

i thought it was the exhaust aswell but all i did was unbolt the two bolt springs and the hangers bolted them back up.

this morning now the car has no cel i didnt do anything besides unscrewing the maf and looking at it to see if it was dirty then screwing it back

 

was there a gasket for the exhaust, and have you check your intake for any oil both could of thrown a soft code (a code that pops up then goes away sometimes after the computer fixes its self).
