2006 Mazda 3: manual transmission..9,000, my car began to hesitate

Resolved Question:

I have a 2006 Mazda 3 manual transmission. I just went to Mammoth from LA. In Mammoth altitude about 9,000, my car began to hesitate. When I drove to LA the check engine light went on. I am going to move to mammoth. Is there something I need to do so the car can adapt to the high altitude?

Ron :

Hello,

The car will adjust in Mammoth once you have been there a week or so and a weeks worth of drive cylces, that being said, the check engine light comes on when the PCM (computer) sees a system fault, when this happens, the PCM sets a fault code, so your next step is to have the car scanned and the code retrived to see what has failed in the system .

Customer:

I hesitate to take it in as I fear getting ripped off any advice there?

Ron :

In most states, most part stores will scan the car for you at no cost and retrive the code for you, if you can do it in Cali, get us a code and we can direct you in the correct repair.

Customer:

I am going to get the code and return with it later, Ron--I will then hit accept. Thanks

Ron :

Ok, get me the code and I can point you in the right direction, sse you then.

Customer:

I ordered a code reader from amazon overnight delivery--I will receive it today. I will send you the code and accept the answer after I get a response to that question--Is that fair?

Ron :

Yes that is fine,

Customer:

The check engine light went off on it's own. Then I checked the code and it is PO126.

Ron :

Hello,

Customer:

hi

Customer:

I just checked the internet and someone noted that the code means thermostat stuck open--if this is indeed the meaning---how much would it cost to replace?

The code P0126 is in most cases Insufficient coolant temperature usually due to a bad thermostat. In most cases replacing the thermostat will correct this issue. This would be more obvious at cooler temp. Start with repalcing the thermostat and I think you will be ok.
