Need Injector Help for 4.3 Chevy

[altautoman]

I have a 2000 Chevy S10 4.3 "W" Engine. I recently installed a .500 Lift Comp Cam, V-Max Intake Spacer, Ported my heads with a valve job. I now am starving for fuel out of the hole. I was told I need stronger injectors to solve this problem. If anyone knows where I could find these please let me know.

Make sure you have 65 psi fuel pressure, this is a vortec cpfi right.

Vehicle has excellent fuel pressure, 64 PSI. When connecting OBDII to system, it show misfire in all cylinders at idle. When reving motor all misfires go away. Once you are driving at get on it, vehicle response in excellent. It only seems to have fuel problem when leaving a standstill.

If the injectors were undersized the power loss would be at high rpms, how is the idle vacuum with all the mods?

If it's starving for fuel out of the hole then you need to get the idle-part throttle mixture up. You should only need stronger injectors if it starves for fuel when you tromp on it and the injectors are working hard.

you need to call jet chips and tell them what youve done, and be prepaired to spend over 400 buck, you need a chip cut for that cam

Is there an easy way to check vacuum, or adjust idle mixture? I noticed today even if I start out of the hole with a power brake, vehicle hesitates for a couple of seconds then revs very fast, spinning tires. But when you let off the brake it will cut out again then kick in antoher couple seconds later. I will call Jet and see how much more money I can spend. Its only money right. As long as the wife doesn't know. I appreciate all the help you guys are giving. This site is has excellent communication!

spray carb or break cleaner around suspected areas to check for vaccume leak, but idel is non adjustable

Thanks for the help, found obvious vacuum line not connected. Don't know how I missed it, truck runs great! Has anyone ever used the Comp Fast Flash programmer? I just ordered one, they claim you can change your fuel/air ratio and dial in your cam with your computer.
