ok so basicly what i have is a 88 gta that i put an 89 350 into, it is the 88 tpi setup, i swaped all sensors over to the 89 block, i put a edelrock tpi manifold on it, removed the 9th injector, and i swapped the cam shaft out, the cam is a .465" intake, .488" exhaust lift, duration is at 224*int, 234*exh, and the lobe is at 114*, it is also a hydraulic lifter cam not a roller and has the matching lifters, the block is also bored .060" over and was decked at some point, so the problem is that the car wont stay rinning, orginally i thought it had a vaccum leak, but because it wouldnt idle i turned the idle up and it ran good at a steady 1000 rpm (vacuum is at 16), so i thought sweet problem solved, i figured id allow the car to enter closed loop to see if threw any codes, i checked after i turned the car off, it threw a 34 and 36, 34 is maf circuit voltage high, and 35 is maf burnoff relay circuit, so i reset the computer to make shure they wernt false codes and started it back up engine light came back on but i continued to allow car to idle, after about 2 minutes of idling the car began to sound like it was stalling, it would choke drop down to about 500 rpm, bounce around there for 10 seconds then stall, the same codes were there and i cant get the car to run right, so i am asking for help, i am starting to belive this is a computer problem that cant be fixed without a custom prom, so if anyone has any ideas or suggestions please help me out here
