surging and idling problems

LXStallion · 04-28-2001, 11:01 PM

My car has problems with surging and idling problems that I cannot get rid of. The motor is a 306 with 10.5:1 comp, trickflow heads, trick flow cam (286-294\.583-.605), trick flow intake, 70mm throttle body, 73 mass air, 30 lb. inj, and a cobra computer. Are my injectors too big? The car is very fast and runs great through the higher rpms but lacks on the bottom end and won't idle. I have the air adjuster on the car but doesn't help. when considering the airflow needs of the car remember that I am at 6000 ft above sea level. i appreciate any help.
