Car has to learn to idle everytime I start it I have a 5.3 from a 1999 z71 in my 87 camaro. I swapped the cam to a 222/222 Lunati and put some comp 918's on it. I don't have a vacuum reserve canister on it. Do I need it and if not, does anyone have an idea of why my car would die like this.

I'll put 5 bucks on it being that your 12volt orange which always supplys power to the PCM is on a switched circuit. It needs 12 volts all the time.
I go through this every time my car goes through tech and they hit the battery cut off LOL. It was a pain to run a wire all the way to the trunk. So I deal with it lol.

I've checked this a couple times. That's what I kept thinking. give me a list of pins that should be hot all time and a list that should be keyed. I will check this again and see.

battery and alternator is good reading 14 V on my gauge and never has a prob starting. and that's with the battery in the back. If the pcm is bad would it still run right otherwise?
