Check engine and security light
Alright last week i just got done putting headman shorty headers on and a new rear end out of a 99 camaro SS (3.42) in my car. since than my car has been acting up. every time i get on it the check engine and security light keep flashing and it feels like it either boogs out for a second or it has a delayed shift, because the car kind of lets up and then jerks you back a little and takes off. for the first week i didn't have my O2 sensor in because i needed to drill and weld it into the header so i thought that was the problem but yesterday i got it put in at the bottom of the drivers side header right before it hooks up to the y-pipe and im still having these problems. any help would be great, Thanks Jay

Yes, get a paper clip and pull the codes yourself, it is real simple to do. Jumper pin "A" & "B" of the ALDL and turn the key to the "ON" position with the engine off. The SES light will start to flash the codes. The first code will 12 and that is normal, the fans will also come on and that is normal. the code 12 will flash 3 times like this. FLASH....FLASH FLASH. Any other codes stored will flash 3 times after this. After all codes have flashed, the cycle will start over and continue until you pull the jumper out and turn the key off.

A code 53 is a rare one but here is what it is.
53. High voltage at battery OR
High voltage at exhaust gas recirculation valve OR
Voltage reference error OR
Problem at vehicle anti-theft system
I doubt it is EGR since 99.99999% of all GM cars will throw a code 32 for EGR before a 53. My geuss is the VATS although I am too unfamiliar with it to comment any further. Are you sure that was the only code. Just to varify after the code 12 you saw 5 flashes...pause... nd then 3 flashes?

yes it flashed the 12 code 3 times then 53 three times and then back to 12 3 times and i checked it over 4 times to make sure 53 was the only one.

I would check the two white wires coming down the steering column to see if they are possibly worn and causing the light to flicker. Also check the wires going to the starter enable relay under the left kick panel. These are wires relating to the VATS system.
