Cel light is blinking!
 

I have test pipes and that's about it, I know test pipes can cause the light to go on but mine Is blinking! Idk if its cuz of the 10 degree wearher or what do you guys think? What should I check or change if its a misfire?

Blinking is usually indicative of a emissions code. I bet its a misfire or O2 code. You will have to get it read to see exactly what it is.

I'm at the dealership right now and they charged me 125 to get it checked out cuz I'm 2 months out of warranty even tho I only have 32 thousand miles smh, are they going to say anything because I have test pipes on?

They'll mark it in the notes probably. That way if your o2 sensors go bad, it won't cover anything but since you are already out of warranty it really doesn't matter.

True, what could be causes a misfire and how much is that usually to fix?

Its possible to throw this code when cold starting the engine, I have seen it on mine. Although in this case I would assume its from your test pipes messing up your 02 readings and causing it.

Wow, $125 is painful. I bought a decent code reader for $100...

I should of done that, would getting a tune get ride of the misfire since I have test pipes on?

Yes it would.

Alright the dealership told me that when I got the test pipes installed the gasket was ripped and there Is a leak, they said that if the crap from the gasket was sucked back into the engine then I'm f*ed, what are the chances of it getting sucked back into the engine and I said dont fix it ill get my shop replace the gasket, and should that fix the problem, and how bad is it to drive it right now with the hole in the gasket?

Not bad, if shít gets sucked up, bye bye engine, but I doubt that happened, it usually happens with cats

Get yourself some Z1 gaskets, tell them you want the Black Friday price ($30)

if the engine runs and sounds fine (the way it did before) does that mean nothing did get sucked up? and where could i go to get the gaskets installed at a good price, but where they will do it right? I am located on long island ny if anyone knows a good place!

and will the Z1 gaskets fit on my resonated megan racing downpipes?

Yes, I have them on my Megan's, lol


And honestly, CEL BLINKING, that's a first, mine just used to stay on

Yea that's why I got scared cuz blinking means a misfire, but now the computer is reset, I still have the leak but until I get this fixed is it safe to drive?

Exhaust leak is fine, embrace your louder exhaust note

FYI AutoZone and and Advance Auto Parts reads codes for free.

Thanks for bringing my mood down :(, smh just threw 140 in the trash, and if the leak is from the gasket is there anyway that while I drive right now that anything can get sucked back into the engine and mess it up?

It's THEORETICALLY possible, but not likely, like not at all, I have put 8k+ miles with a blown gasket

i just installed Berk Test Pipes, and my SES light went on. I'm going to install the O2 sensor extenders in the morning and reset the SES. That should clear everything up. Maybe that's whats going on with yours too.

Put some stainless steel wool in them too

the whole thing thats bugging me tho is that my cel light isnt just on its blinking, i had the computer reset today at the dealership before i left and 20 miles later the light blinks like 3 or 4 times and now its just steadily on, then like 2 miles later it blinks again a couple of times, so what do you guys think is causing it? could it be because of the blown gasket or because of the 10 degree weather thats throwing off the a/f ratio?

If there's a leak near the Primary O2 (before or after), it will read lean, intermittently add or pull fuel (high trims) attempting to maintain stoich, and possibly cause lean misfires.

Not to go off subject, I just bought my reader for 35 from amazon. It reads from the torque app off of android market. I ordered my O2 extension bungs from z1 and have reset my SES light a few times via the app. Gives some good info just a fyi.

thanks for the info! im going to get the gaskets replaced with the z1 gaskets today

alright so i got the gasket replaced but my cel light is still blinking, could it maybe be a bad tank of gas? or does it mean i need a tune soon?

Why don't you listen to this guy!?

You keep guessing what is wrong you are gonna spend lots of money "thinking" it may be this, it may be that... Etc etc..

Go get it read and start from there ...

Google helps... I'm having the same issues and I narrowed it down.


There are lots of codes it "could" be throwing.

Either P0300 random misfire, P0133/P0153 slow sensor response.

Until you know exactly what is the code how can you trouble shoot properly. People here have wealths of experience but to properly diagnose your problem. You have to know the code and work through the process of elimination for the causes.

Get smart on your car, use the Internet, your smart phone and your "free" resources before spending money on things that don't need to be fixed.

Good luck.

i got it read, it said i have a misfire and exhaust leak ill check what the numbers are tomorrow!

Take it to the dealer to diagnose the misfire

i already did 2 days ago, they said it was from the test pipe gasket leak(exhaust manifold leak) and i got that fixed today but when i was driving back from the shop the light was still on and blinked when i was going around 30, but the car seemed to run exactly the same as when the light wasnt on, no limp mode or any weird noises coming from the engine while its happening!

So if there's no leak, take it to the dealership...

How did you fix it so quickly btw? If you say I bought a gasket from AutoZone I will say you still have an exhaust leak


Find a new dealer btw

Why don't you just post the code?

Or are they just telling you this and you are repeating it back to us?

Misfire code should be a P030x series number...

The last digit is the cyclinder that it is misfiring on.

The exhaust manifold is your stock headers.. If they weren't removed when you put your test pipes on then you shouldn't have a leak there.

Here is an example of using the Internet if you have the code number

OBD-II Trouble Code: P0300 Random/Multiple Cylinder Misfire Detected

No need to post with exclamation marks as if you were yelling when people are trying to really help you.

If you are that inept about mechanics, take it in to a reputable local shop.

i dont want to take it back to the dealership because they charge insane hourly costs i already paid 140 with tax for the diagnosis! and i went to a shop that had the gasket cut out and they showed me the old one and it was burnt threw completely on one side! in a couple of days my tank of gas will be empty that i filled up at a sketchy gas station and the weather is going to be warmer and if the light is still on ill take it to z1 motorsports and see what they say.

i appreciate the help and i am not trying to be rude, im just trying to explain the situation the best i can, and i dont think the diagnosis sheet they gave me from the dealership says the exact code that it was throwing, it just says that it was a random misfire and an exhaust leak.

Some DTCs, especially those related to emissions, take a few drive cycles to clear. If you fixed the problem, it should disappear after a day or two or three.

even if its blinking?

There could still be a leak (hairline crack) or the O2 sensors themselves may be damaged.

If you can get the exact codes its throwing it will help pinpoint the problem more quickly.

There's different codes for various O2 problems (out of range, failures to warm up, etc.), high fuel trims, and also misfires -- all three kinds of codes could be in there.

BTW, if autozone won't do it for free, or its a pain to drive to one and have them do it, any walmart or autoparts store will have very inexpensive code readers (make sure its one that will give you the actual DTS code numbers -- not just clear CELs absent of the info!).

Something like this http://www.newegg.com/Product/Produc...0KZ-0001-00001

I usually see them in either orange or blue -- just make sure it gives the actual codes.

It should be around $25 and an invaluable tool for troubleshooting problems! They generally come with a listing to look up the codes, otherwise you can just go here OBD-II Check Engine Light Trouble Codes

There's links for generic codes as well as Nissan specific ones.

You may still have to follow up trouble shooting the old fashioned way (i.e., under the car with a flashlight and tools), but to get pointed in the right direction, using the OBDII info is greatly helpful!

Good luck!

i am going to to get the code read tomorrow because i looked at the sheet from nissan and they didnt post any of the code numbers

the code was Po300 random/multiple cylinder misfire, i cleared it today in the morning and hasnt come back yet.
