I have had the same problem, I bought an adjustable idle spacer and that helped tons. I would have never believed it but it did. I also put an aluminum rad in to keep temp as cool as possible. My gauge never goes above 180 and it runs awesome all the time now. The computer does something to the timing and fuel curve when it warms up so I keep the computer thinking its cold all the time. Runs rich but good as hell, Dave

how did the spacer help when you put it in, because i'm going through the same thing right now. the car runs fine for like 20-25 min. then when it's been at running temp for a while(190-195) it will start acting fuel starved. it's gotta be something electrical, because when i shut it off, i can't get it to start due to no spark. i already changed distributor, cap, rotor, coil, and bypassed the msd. i have also changed out a multiple of sensors, and changed the fuel system out. i hope ya'll have something, cause i'm starting to get desparate!!!!
