hey guys, new to the forums but not new to these cars.

I've had my 95 camaro for 4 years now, I swapped it from the 3.4 to the LT1. it has the t56 tranny, lt1 motor and engine harness/computer from a 95 z28 donor car. it has 2 o2 sensors at each collector for my mid tube pacesetter headers, and a catless, straightpiped exhaust from the y pipe to a magnaflow catback. Im not sure how many 02 sensors were in the original z28 so maybe thats an issue?I just got it up and running and took it out for a couple test drives, after getting hot it will randomly stall, and will not start back up again unless you give it a decent amount of gas. however when it does get running it dies under any load past 1st gear. just wondering if anyone else has run into the same problem, i am getting a scanner for the obd1 system in the next coupple days but i figured id post in the meantime.

thanks
