Default 1995 SSE Rough Idle - FIXED!!!

Ok, I'm starting a new thread because the other one that I had was technically a different problem. I replaced the IAC a couple days ago and the TPS tonight. The rough idle that I have been having went away for a few minutes after I started it up for the first time with the new TPS tonight. As I was letting it run while moving cars around it started to idle rough again, after maybe 2-3 minutes. Is the TPS something that the computer will have to "learn" for a while before you can expect everything to straighten itself out???

I've been planning on retesting them to make sure I didn't mistest them initially, but it'* been too cold. But, no I haven't tried another coil. Maybe I'll go on ebay, see if I can find some good used ones for cheap just to have around. It would be better to get some SII L67 coils vs my L36 ones right???

I'll see what tomorrow morning'* cold start will bring, that'* when I have most of the problems. I'm also picking up an AutoXray AX6000 from the board in the next week or so, finally something that can read OBD1.5.

92-95 L27/L36/L67 are the same.
96+ L67 toss a slightly hotter spark. (or is it 97+?)
Meanwhile the L36 retained the 92-95 coils for the most part.

Still was acting up this morning, although not quite as bad as before. Time to try the coils.
