This is a very dangerous and serious concern. Do not store car in the garage. I would not drive this car. This car needs to be serviced by a qualified automotive service technician .

One of the most likely causes are squirrels or other types of animals chew into the plastic fuel lines. I have been told it is the ethanol in the gas? Others clam that it is the soy in the wires. Rodents have been reported eating the wires and fuel lines of cars parked at airports?

Hi there I am a tech mechanic and I am going to start n say this to test the battery and alt. Don't just test it running that only a part of it OK start with the heart of the car (battery) take the leads off test them without them it should be no less then 12.3-12.4v n then cut n clean the term. Wires n if need be replace them NOTE (don't test the ohms most people will tell you to but no you can have Evey wire on the big wires broke but one and the ohms say they good but they are not bc the meter is only putting 1-1.3v. On that wire if you want to test them do a voltage of drop test on the same side pos.to pos n nev to nev don't just test the two test body, motor also test the starter the same bc most the time it is a bad conn or even a open circuit or a ground at the back of the car ) and use a computer safe test light and test the fuses and the power box and don't forget to both of the boxes need power and ground too some fuses only have power with key on and don't just touch them hold it on them few sec and if the light dim down or go out it bad or open circuit note to that you need to pull up wire diagram of the circuit and see what Evey thing is on it and make sure you are not missing fuses also check the boxes with ur meter for the 12v only touch them with po test lead and the other one to a good ground also to make sure ur getting good testing and test both power and fuse boxes with the meter 4 12vyou also should have a alt fuse or rely and the battery does also have them to its called a battery saver and if you have a bad rely or a light in side ur Gage pan. Out it will not work but for your rely you can test bench test them to but it is ify you should get whats called a jumper wire and put in tm that circuit to complete it and the car start and system work right now if you do like that it works it means that rely is out NOTE THIS THOU YOU HAVE TO JUMP IT RIGHT OR YOU can BLOW up the COMPUTER system LOOK IT UP ON YOUTUBE I BET you can DO IT STEP 4 STEP one more thing don't 4 got the hurs. Wires at the back of the alt n it could be the ignition lock and key and the ignition switch to my money on a ignition key and switch thou Louis don't know what he doing about the only thing that he got right is his name!

It sounds to me that your Powertrain Control Module (PCM) is going into "Reduced Power Mode"(sometimes called "limp-in mode"). If the engine is running that bad or if the PCM is going into reduced power mode, the Check Engine light should be SCREAMING at you! If it is not, you probably need to do a "bulb check" to make sure the check engine light works.
There are several hundred things that can make the PCM do this. The ONLY way to find out which one is causing it at this time is to scan your computer network for fault codes and diagnose accordingly.

This may be related to the antitheft system The system is known for turning off the starter and/or injectors when it fails. Is there a light on the dash that says SECURITY? This is a common problem worth looking into. http://www.diy-gm-security.com/

alternator,or something in the climate control, you just need to listen and track it down, once you know where its coming from you can fix it

Double check your work. They put fuel caps on the ends or inside the filter. Is the filter on the correct way? Filters have arrows for flow. Take the filter back off and make sure the arrow flows toward the engine.

Are you saying that the dome light doesn't work when opening the door? Or when using the dash dimmer control to activate it? Or both?
There is a position on the dimmer control of most vehicles to disable the dome light. Verify that you don't have it in that position. It is normally at the opposite end of the dimmer rotation from the position that turns the dome light on. If the light doesn't work from either the dimmer or the door switch, check the bulb. They do burn out. If you replace it, do not touch the glass of the new bulb directly when installing. They get very hot and the oils on your fingers will cause premature failure. If everything seems ok (dimmer/door switch/bulb), check for a blown fuse. Otherwise the problem is in the car wiring.

There's a bolt pattern to follow and torque speculations as well. Search online for your vehicle and type in R&R oil pan gasket for a (vehicle year make and model, engine type.) Example : R&R oil pan gasket on a 1982 Toyota celica 22r engine.

Have the alternator output tested for any over / under voltage at any AutoZone type place. I might next look at the voltage regulator. Also, make sure all your alternator, battery and ground terminals are clean and with good contact. Do those simple things first. A smell suggests the possibility of a short somewhere so that testing gets more elaborate.

First step is to get the computer codes read. Your local auto parts dealer may read the codes for you at no cost. Once we have the codes, we can advise you further.

If you bought from them it can. Manufacturers will let after market fob's be learned in the system. I have never been able to program an aftermarket fob to an aftermarket system. Not even with a scanner.

brakes and rotors will not cause noise unless they are badly worn and this will be evident on inspection
most noise will be from rubber suspension bushes and sway bar and shocky rubbers
I would suggest that you get quotes from suspension accredited shops and have each shop show you what is worn and what is ok
ON good roads ( hard surface) suspension units should last 60.000 miles before requiring repairs ( barring road damage)
