This may be normal I dunno though. I got a MAF Engine Harness from an 89, and I got an A9P Computer. Im using the stock MAF Meter right now with 19lb injectors until im sure all is good. Anyways I fired it up and it was great for about 10 seconds then it stumbled a bit and died. It did this 2 maybe 3 or so times and didnt do it again but the idle seems kinda rough and low to the point where my instrument panel lights dim and then it'll climb a tad again. It seemed to idle real good for a few min. and then have a hickup again, but it never died again. Does the new computer have to relearn itself? Ive doing some searching and have heard the computer needs at least 2 to 3 cool to hot cycles before it has relearned itself. Does this sound what its like to you?? I floored it a few times and its fine no pops ticks, nothing sounds off, just worried about the idle!
