Question about Chevrolet Cavalier

2 Answers

First off i have had nothing but problems with my 02 chevy z24. First paid 800 dollars to a dealership for the security light and theft light coming on. Turned out it was an after market security alarm someone else that owned the car prior had put in. Next i have nothing but problems with my check engine light coming on. First it was the coils and spark plugs were shot. I had all of the replaced. Next it came on again and i had the o2 sensor replaced. Now there is a loud clucking noise when i drive down the road. It feels like it is coming from the front end. After i got the o2 sensor replaced the check engine light came on again!! I dont know what else to do. Can you help me out with this???

    the loud clucking noise does slow down when you decelerate or does it keep up with the rpm of the engine

Or it might be just an exaust leak and the o2 sensors are reading a lean fuel mixture. check to see if the egr valve is leaking

2003 chevy impala starts anti theft comes onput in gear dies wont do nothing


My impala did same thing and then would not start. I suspected anti theft problem I then had chevy dealer change ignition switch. It fixed problem second time I wasn't going to pay $ 750 for so I bought $40 dollar switch on ebay. It was an easy job following great video on you tube. When I went to start car it would not go. While doing relearn procedure (hook up battery charger before starting procedure) I got very tired of door chime so I found it was coming from left front door speaker. I removed wire to stop chime. When i went back to relearn procedure car started right up. I have a steady security light on but car has run fine for months. If you cruise and heater fan has also stopped working add wire from switched terminal on ignition switch to power feed wire on heater. It fixed both problems on mine.

Im almost sure that my anti theft system is stopping my 1998 chevycaviler z24 from starting do i need to take it to a gm dealer


If it were my car I would definitely take it to a GM Chevy dealer to have it checked out.

If the anti theft system has kicked in to stop the car being started you might find a security warning light on the dash.

this is a common problem with the new Chevy ignitions --- sometimes it is the ignition switch and sometimes it is the microchip inside the key itself. your best and cheapest way to get this fixed is to call a automotive locksmith and have them come out to your vehicle and determine if it is the key or the switch,,, either way it will only take 30 minutes to change out the ignition - or 10 minutes to re-program the key to the car. on the low end it will cost you 85 dollars -- on the high end it should not be more then 145 dollars ( this is with the new switch ).

occasionaly my car still does not start. Not start how ? When you turn the key in the ignition to the start position , what happens ? Does the engine spin an not start or nothing happens ? Some anti-theft systems disable the starter an some disable the fuel injectors .But no matter which the security light will lit on the instrument cluster. Plus codes would be stored .

Car will not start and the light for anti theft comes on blinking


It's mostly likely security code enabled. Take it to the dealership and have them reset the code. Bring your license, registration and insurance. They should be able to reset the code. It's somewhat costly though, it might cost around 200 dollars, but it takes about an hours worth of work for them.

2001 chevy impala security light keeps coming on


This is a problem with chevy vehicles that have the system theft light. after a couple of years of using the key, the lock tumblers inside the ignition switch tend to wear out and so causing the system to think it's being stolen. Now you have to put the key in and turn the ignition to the on position, without cranking the car and leave it for 10 minutes until the theft light goes out. Very annoying especially if you're in a hurry. The dealer cost to repair the ignition switch goes for about $600-$800. that includes re-teaching the key.
