i have a 2000 cav 2.4L with heavy mods t3t4 ho intake 3'' exhaust msd 525cc injector gm sc re-flash hp tuners just to name some of the stuff . but when i drive it once and a while it likes to stall at a light or if i gear down when the car is pulling down if i push the clutch in to roll up to the light it stalls plus it idles a little ruff and or surges about 200-300 rpm than it usally catchs its self and smooths out plus the car must be warmed right up or it will stall as soon as u stop it the car is untuned but i have corrected for my injectors and turned up the idle to 1100 and it has helped but its not perfect any advise is appreciated. if u guys need anymore info or pics i'm more than happy to get it for u

well i solved 98% of the problem. I'm sure everyone knows this but me but i thought i would let people know just in case. i went under fuel control and raised the DFCO 300 rpm and the mph 10 and now the drivablity is sooooooo much better almost no problem driving in stop and go traffic this helped my car more than correcting for my injectors and raising the idle combined.
