Well long story short.
Got one of my old camaro's back for free..
Gave it to my buddy since he needs a car to start working his second job..

Problem..
Car idles for about 20 seconds then it dies.
Put it in reverse it dies. Drop into any gear and it dies..

Wasnt doing this till yesterday when he was looking for a parking spot in the DMV parking lot..

We've replaced fuel pump
Spark Plugs
02 Sensor
Wires
Dist cap and rotor
Wires
Vacuum leaks are gone now.
Fuel Pressure Regulator

Not sure on why its doing this now.
I mean when I first got the car it didnt run, and I got it running a couple years back, and its been sitting for a while since I sold it.

So I dont know where to start.
Most of the car is brand new and still under lifetime warranty for parts..

Trouble codes that are being thrown out are 33 and 43.
I mean the MAP could be bad since I never replaced that.

I dont get it.. Any ideas guys?

 

idle air control may be dirty or bad and i would also check the tps
