ok i have the airbox mod and res delete and magnaflow muffler its a chambered muffler and i have had a cel since i did a airbox mod so i figured it was from the intake and was a lean code but i took the muffler off one day to put a straight through muffler on and my cel went off the whole time i had that muffler on then i put my old one on and the cel comes back on wtf any ideas

 

find out what code it is, kinda hard to help with no info

 

sorry dude i dont have a reader i cant get the code

 

autozone pulls codes for free

 

Pepboys, Autozone, Advanced Auto will check it for free...

 

lol damn it that means i gotta drive an hour to get it im sure its a lean code tho it came on 10 min after my airbox mod

 

Weird it would be the air box because CAI's dont even set off lean codes often.

 

yeah they do...look there are alot of ppl who get codes after doing intake these computers are very picky

 

There are also I large amount of people that do not, I didnt get one and I ran the air box and CAI before my first tune... MY buddy didnt even get a lean code when his air box was crack and didnt have a seal between the inner pipe and the box..

Do you not have a tuner near by you? Also with that OTTP tune I do not see you running lean.

 

Hell I got an EVAP code thrown after I put my CAI on...had it cleared and it never came back. It is either a lean code or the Evap possibly. It is worth taking it to get it checked out if you care to lol.

 

i dont have the ottp in yet just air box and exhaust what do you think it could be then there is no other reason a code would pop up after intake other than a lean code

 

Change back to stock intake if you dont want to go to get the code checked. Drive the car around a bit and see if it goes off.

 

it went off when i took the muffler off dude thats my question why did it do that

 

again, we need the code, we can answer questions when you won't give us info.

 

CODES DUDE! For all we know its random misfire. If your gunna act like a dick about me suggesting something then you deserve no help. We are trying to diagnosing in the dark. If someone else knows what it is from personal experience great you win. Nobody has chimed in just yet about it that has.

 

muffler bearing went bad, the new one took care of it.

 

dude i didnt mean to be a dick sorry but i wont be able to get codes right now so i guess im fucked i will update when i get codes i guess i thought maybe someone would have an idea of what it was i guess i was wrong again sorry

haha i checked the bearing it was good

 

for all we know it could be because you didn't screw your gas cap on right.

 

you forgot to fill up your supercharger pulley.

Get the code. Then let us know.

 

alright look im not ******* stupid i understand ok i will get the code tomorrow sorry guy jesus

 

Theres got to be a place in blue earth that will pull the code for you. Isnt there a napa there? Check out some auto places.

 

alright went to kato today and there were two codes the first one was a lean code as i thought but there was another one P0603 and it said "control module long term memory reset" and the explanation was " not set ecm detected the checksum did not match a previous checksum" and at the bottom it says failed ecm so what the heck does that mean

alright that code is just because i unhooked the battery so why would a lean code go off when i take my muffler off

 

PO420 "pending" if you have no cat on the car, i want it to go away...

i swear i've cleared it at least 100 times...

 

You can shut the cel off through a tune or they make a, im not sure what its called, but it extends the 02 sensor out of the pipe a little bit so the code wont show up.

After they cleared it did it come back on? Was it p0171? A tune will take care of it.

im running high flow cat and i didnt want the cel to happen so i got one of the o2 sensor extentions off ebay, its a right angle

here is something similar to what im talking about
