The intake itself is oem, but i guess the box filter is aftermarket. I find it strange that the light is just coming on now when I've had the car since January. The tech said the car detected that it was running lean at one point, causing the light to come on.

I usually rest the light myself, but it comes back on after a few hundred miles..sometimes more. It is back on today and I am supposed to be back at the dealer Wednesday morning.

Any idea what is going on here? I've read several times on the forum our cars have a history of issues with the gas cap. I was thinking maybe replace that and see what happens :confused:

Yeah, I was searching around the forum earlier. I came to the conclusion of what you just told me :icon17:. I also read a few posts from you about this code haha. It's a PITA and there are many causes. I might just clear the light when it comes on (just ordered an OBD II today). If I go to the dealer this second time and they still come up with nothing, I'm going to ignore it.

As far as the Uprev tune..where would I have to go to get that done? Like a performance shop? I'm assuming the dealer probably doesn't do it. How much does it cost?

Were you able to pull a code it was throwing? If you haven't just go to the local parts store they will gladly do it for you and tell you what could be wrong in hopes you buy the parts from them.

Got the code read.. P2A00. Had something to do with the O2 sensor? I remember this is similar to what the dealer told me the first time I went. (I was out of town and stopped at a Chevy dealer. He cleared the code and told me if it comes back to get it checked out.) A couple of months of so later..light comes back on. Nissan then tells me the bad gas or something with the air filters.:mad:

I don't want to make this too simple, but I had this issue a few times early on with my car. I had the dealer check it out and it was "vapor leak" around the gas cap. The SES light is focused on emissions. I started just pressing harder when replacing the gas cap and gave the cap a few extra cranks . Never have had the problem since.

Keep in mind that with the arrival of colder weather the seals change a bit. My old 90 TT developed all kinds of gas vapor leaks when winter arrived only to disappear in warmer weather.

Just got back from the dealer..again. They said they think it might be the sensor thats causing the P2A00 code to be thrown. Replacing the sensor is almost $600. He said "but there could be other issues with it". Say what I took out of it is that they want me to pay $600 to fix something on the CHANCE that it could be the problem??:mad: I told him forget it, I'll trade the car in before I do that. What now?? :confused::shakes head:
