This can be a bad switch, or frayed wiring, usually at the hinge area of the driver's door where the wire flexes each time the door is opened.

You need to check the O2 harness for melted spots. If not then you may need expensive O2 sensors. Codes say too rich one side and too lean the other. http://www.obd-codes.com/trouble_codes/

Does your car have a chipped key? Maybe you had a key made that isn't chipped? Can you try starting with a different key?

Ned, Thank you !! No one has said how you get to those starter bolts for removal. We are going after it now.. My son blew out clutch and we are doing a father son repair. We have removed exhaust, drive shaft and most everything, but that starter has halted everything. Now to get the starter out.

That top bolt is not visible from any angle.

See attached pictures

It sounds like the battery and if you continue cranking it with low amps it can also damage the starter. You ccan take it to any auto parts store and they will come out in the parking lot and check your charging system and battery for free then you will be sure what is wrong.

Make sure you have a fresh battery in the garage remote. Drive away about a block and park. Press the two outer buttons on the IS for about 20 seconds , they will flash 10-15 seconds and then go out,erasing any old codes in the car.
Then select a button position, 1-2-or3 on the car for your garage function. Hold your garage remote to the car's button pad and depress the garage remote button and the cars button (1-2 or3)continually. The LED in the cars touch pad will flash slow, then fast then go out. Once these steps are completed the car and your hand held are syncronized...thh car has recieved the remote function. That is step 1 for all vehicles.

Now you need to return to the garage and "introduce" your car to the garage door opener's receiver. Depending on the brand there will be a "learn" button on the garage door opener. You will climb a ladder and push the learn button as per instructions in the opener manual or on the stickers on the opener motor itself, if it is a Chamberlain, Liftmaster or Craftsman....
These buttons will be pressed to erase old opener codes or program to add new devices...which is what your car is.
Each opener has its own series of functions but generally after initial set up of the ceiling unit, you will depress the learn button and hold for several seconds. Then within 30 seconds , you will depress the cars button for about 2 seconds and release, the lights will flash on the ceiling unit in the garage indicating success and the next time you press the cars button the system works.
For complete detailed instructions go to the HOMELINK web site. It covers most cars by model and openers by brand with VERY detailed instructions.
Nice car! Enjoy and post back with results

Take it to you nearest Auto Zone. They will hook it up to their computer and tell you what the problem is for free!!! I believe the vehicle will have a computer port. 2004 and up I think it is.

HI. it will be necessary to replace this relay. asap. The relay is suffering from circuit damage. This type of damage will not allow the relay to completely open, thus, causing the battery to drain, when the ignition is in the off position.

the only way to get them out is to remove the unit from the car and disassemble it. if you replace the unit it will go to an exchange company and if you request it they will send your cd's back.

Thanks for using FixYa!

You need a special tool to fix timing problems. You'll need a timing gun. Most cheap garage shop has this tool. Just bring your car to a cheap shop and have your car properly timed. This is only a 15 minute job. I hope this helps.

Have a nice day.
