Have someone do a back pressure test on you catalytic converter. I had the same problem and it turned out that my converter was almost completely plugged. I was also getting a check engine light indicating a misfire on cylinder 4. Once the converter was replaced, the problems went away.

sounds like your passlock sensor on the ignition barrel is faulty. you will have to go to the dealer to have it replaced because of the programming after replacement.

SOURCE: Reset the security system after installing a swicth 2001chevy Impala

did you change the key? if you have it more than likely needs programmed as most of the gm's have either a resister based immobilizer or a passlock system. If its the same key check that you have all the connecters back at steering column as you may have disturbed the vat's one.

SOURCE: my 1998 Chev Cavalier Theft System light stays on

If the car starts and dies right away you may have a pass key sensor fault.
Try to start the car,if the car dies right away just leave the key on and watch the security light in the insturment panel,if it begins to blink leave the key on until it stops blinking (apx 10 mins.) this will reprogram the pass lock to the pcm and may solve all your problems.if the car continues to die after running a min or so then you may have other faults,or if the car dies right after start the pass lock sensor may need to be replaced.

How do I reset the security system on a 2001 Oldsmobile Aurora


If the security light is on you can try the 10 min. relearn procedure . Turn the key to run ( not start ) an leave the key on for ten min. If the light goes off in ten . min. turn the key off . Then start the vehicle . If the security light doesn't go off there is a hard fault an you will need to have it diagnosed by a repair shop that knows how .

2007 chevrolet impalahave a 07 impala runs great till ur rpm meter goes past 4000rpm then drops down to 0 runs bad after shut down engine for around 10 mins then runs good again check with scanner no


It needs a scanner on it to find the problem while driving it. Several things can cause this. At 4000 rpm's in park the ecm will suppress the engine. this would be the Neutral safety switch. So going from there, if not the switch, it could be wiring or a bad buffer in the ecm.

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.

Security light flash no security system on truck


sometimes turning the ignition on 3 times quickly without starting will reset the computer. If the van has power locks and keyless entry then try using only the keyless entry. Sometimes your car wont have a alarm but an anti theft device which will not allow it to start if it goes off or something triggers it.

How do i reset the security system on my 2003 chevy impala


Are you reffering to the alarm or the pass lock system that put the theft light on.....If its the alarm the put the key in the door and unlock it. If its the pass lock system put the key in the ignition and turn it on and try to start the vehicle. After it shuts itself off leave the key on for ten min until the theft light stops flashing the turn key off and try to start it again. This may take a few times....
