Long story short, I changed my clogged injectors and replaced them with the same oem injectors. Now the car idles at 500 rpms when I pull it out of gear but doesn't die. Tap the gas, it'll rev then idle at 900 like normal. Anyone have ideas as to why, or how to fix it?

 

Why are you running stock 24lb injectors on a H/C LT1? Or is this on another car?

 

+1 - CC503 + LE2 Heads = Why the heck? However, the problem probably lies with your IAC. Can you log the car with datamaster? It will help to see what the IAC counts are at and if your IAC motor is functioning. You might wanna try the reset procedure on your IAC to see if this helps.

 

Shop that dynoed it never told me what the duty cycles were on the injectors so I thought I was alright. But what size should I be at?

 

If you truly are pushing that much power to the wheels (same car as your sig?) I'd say those things are at 100% most of time. I'd go with a minimum of SVO 30's and maybe a tad bigger.

Gonna have to have it reprogramed when ur done.

 

SVO redtop minimum, greentop maximum. Anything you find in between will work as well.

 

Ok thanks
