so last weekend i did the oil change and everything was fine till yesterday, when the car driven for more than 30 min, when i will get to a red light or complete stop sometimes it would idle and almost turn off and the CEL turned on on me, i talked to some mechanic and said it can be a vacuum line, what you guys think? thanks

 

Pull the code from the CEL, it will tell you what is happening or at least tell you where to start looking.

Nothing about an oil change should cause an issue.

 

thank you sir, where is the ECU located at? passenger side under carpet?
do i need to take the code out with the scanner or can i use a paper clip and check engine will blink? im asking this because thats how i did it on my honda. lol

 

OBD scanner port is located on the driver side beneath the panel below the steering wheel column.

 

Moved to the correct subforum

 

It's not the blinky Honda kind.

 

haha, thanks i know hondas are better..... jk

thanks for all the info guys.
