'94 GT, Manual, Bone Stock, Very Well Maintained. here is the problem, short but sweet ... if it is cold outside: car begins to fire out of intake, give it gas the backfire moves to exhaust, barely moves forward while car bucks violently, stalls, restart and the same thing for a few more feet then stalls, next startup the rpms skyrocket and upon dropping it runs as normal. if I leave the car before 3 starts the cycle of exactly what I described starts over. if car is in stop and go traffic: eventually voltage drop (I assume that's a byproduct of loss of vacuum), car bucks, backfires out of exhaust and stalls, restarts hard and with any gas fires out of intake, runs for about a quarter mile no faster than 15mph then stalls, restart and backfires out of exhaust then stalls, upon 3rd start rpms spike then runs fine. I have ideas such as vacuum leak and timing, but I don't understand how it could follow the exact same behavior every time. Weird. any ideas??
