Well I have been having this problem ever since i can remember. When i start the car cold or hot start the car seems to spudder until you can hear/feel a definate good feeling that the car has warmed up. It takes like 3-5 min every time. When i drive it without warming it up it miss-fires like it has no power. but when it is warmed up the power is flowing. I have a 306 port/polished,springs,valves heads, 4.10 gears, Tremec 3550 , holley systemax II upper/lower, bbk fuel pressure regulator, 190lph fuel pump less than a year old, cold air intake. If anyone can help please ... I would appreciate it
