I have a 2003 350z with a GReddy twin Turbo pushing 5 lbs of boost. The service engine soon light comes on every once in a while. I was told that it would do that every now and again. Now, it is blinking! It will not go away. What should I look at?

 

well def. dont start or drive it if it is blinking..i have never had an engine light come on being boosted so i dont see why it would be normal to throw the ses light whenever..

do u have cats on the car? is it running different when it is running..what were u doing when this happened

 

go scan the code ..autozone or advanced auto does it for free

 

in the manual it says a blinking check engine light means a misfire

 

Correct if it flashes it means bad misfire. Do NOT drive your boosted car with a misfire. Check you plugs one might have gone bad or a coil pack may have failed.

 

he just says the light is on...it would be very obvious if the car is misfiring so seems like he would have said that but idk..

op is the car misfiring? scan the code and see what it says for a start... i also would not rule out the cats if the car has cats on it if its not misfiring

 

I am new to turbo's. How would I know if it misfires? I don't think it is; however I am not sure. When I drove it last night, the light was not blinking.

 

having a misfire has nothing to do with being turbo..It is when all cylinders are not firing and it is missing a cylinder or two or 3 or whatever...u need to scan the code with a obd scanner...Does the car spit and sputter or run perfectly fine? sound any different?

 

Scan for the code or this is a useless thread.

 

generally when it blinks its probably damaged cats....but check the code to make sure
