There should not be problems. The only thing is some can be taken off with a 22mm wrench but then some have to be removed with a O2 socket, which is a regular socket that has a cut out down the side for the wire to slide in. This is the major problem. Other than that , you can do this within no time. Be sure the sensors have anti seize grease applied. Also, aftermarket is just a good sensor as the OEM.

Try replacing the fuel filter and locate the fuel pressure regulator it should be located on the top of the motor at the area where the beginning fuel rail is, ( the fuel rail feeds the fuel injectors) if you notice the the pressure regulators vacuum hose is broken replace also if the pressure regulator appears to be wet with gas replace it.

With all of the lighting circuits going through the Lamp Outage Module (LOM) I think replacing all the bulbs and insuring that they are the correct bulbs would be a good first step. If the problem still occurs, then I would have to suspect a bad LOM and a replacement would be needed. You can get a new one from a dealer or possibly a salvage yard near you by checking www.car-parts.com.


let me know if you have any further questions or need any more help



my best to you

sounds like the trunk light switch may have gotten knocked loose .. that would leave the trunk light on all the time and would run the battery down in a few days even if fully charged to start with .. you can take out the trunk light to test that theory .. the alternator will only put out what is needed and thats probably 30 amps with everything on .. to test its maximum capacity you need to hook up an external load and you have to run the engine at a specified RPM ... for a quick test.. if your alternator maintains about 13.2 volts at idle with everything turned on .. then its gererally working ok ..

If fuses keep blowing, then there is a dead short somewhere,. My advice would be to go to an auto electrician. You did not mention for which circuit/s the fuses blow.

Check your transmission line's, also look under your car if leaking between engine and transmission more then likely it's going to be your front transmission pump seal, transmission will have to come out to replace front seal.Don't let it run low on transmission fluid or you will have to replace or overhaul your transmission, not cheap.
