Keep getting CEL. I need help plz.
 

Need your opinions everyone. I've posted my problems a few weeks ago saying that I'm on my second reman engine. After 30k miles it's been replaced and now at 60k they had to swap it out again. My problem, ever since I got my car back, the CEL keeps going off after 2 days of driving it. I notice it will flash a few times before going solid and staying on. I'm almost fed up with the dealership (Galpin Mazda) in Van Nuys. Once the new engine was replace for the second time I had a CEL. I took it in, and they told me the crank sensor was bad and they replaced it. Took the car home, and two days later CEL. I brought my car back to the dealer and then they said my coils are bad again and they replaced them. Two days later CEL again. This time they told me I have a fuel leak from the hard line and I replace it. I was really upset so I asked them to show me. They removed the back seat and started the car, I then saw gas leaking all over the place and it filled up like a swimming pool. So they fixed that problem. Now after having the car over the weekend, I reved my car to 6k rpm and boom I get another CEL. WTF is going on with my car. I feel like it's falling apart. I really don't want another car, but this is happening way too much. I've been really sad for the past month or so.

Did you happen to get the code form the CEL this time?

No I didn't. Now that you said, I will try and ask them when I pick up the car. Its been two days already and they haven't called me to tell me what's wrong with it.

Yeah dude, get that CEL code this time. Without you knowing, it seems to me like theyre just charging you for whatever the hell they want, and not even correcting the problem..

That's what I'm scared of. The fuel leak was a big problem when I saw it. They told me that I had a misfire at 4k rpm because of that.

... fuel leak? wow ... what kind of fuck up dealership that cant even get the fuel system right ... even I know how to replace my fuel pump and shit and success on the first try ... I guess they dont really cared about customer's car.

Anyway, you should really get the CEL first. post it up here. and see if we can figure out the "true" cause of the problem. since it seems that they're just throwing random "bullshit" at you so they can leech tons of $$$ outa your pocket.

See if anyone local can help you with that. Meh, if you're in NYC I bring my pocket scanner and plug it in, 10 seconds job. jeeze.

Thanks everyone. I'll give them a call and see if I can get the code. I'm so scared to keep my car, I love it to death but I cant afford to keep having issues like this.

So I went to Galpin Mazda to pick up my car yesterday. They said they replaced the O ring seal on the fuel injectors, and the CEL is gone. So when I picked up the car, after 10 min of driving it, I rev the car above 6k rpm. BOOM I see my CEL again. I asked for the code this time, and If I remember correctly, the tech said it was PO302. any help would be appreciated at the moment. My car has been with the dealer for over a month and I'm going crazy. I don't even feel like I own it anymore :mad:

P0302 is a rear rotor misfire.
First action to resolve this issue should be to change out the spark plugs.
Then you look at replacing the coils and/or ignition wires.

^^ Like Jon said.

Fuel Quality matters too. Happened to me.

Thanks everyone. I have already changed all plugs and coils prior to this. They have also been checked since I get the same code, but everything still looks fine. I get the CEL when the car goes about 6k rpm. That's why I have no idea what's going on anymore.

If you changed the plugs prior to this, verify that the ignition wires didn't come loose and are secured to the plug.

and make sure that there is no high resistance in the wires and they are in the right places....

and make sure your SSV and APV are functional.

and tell the dealership how much they fail.
