Thanks! That did the trick.
Upon further analysis.. I realized it was throwing the code because I don't have an IAT sensor, not a critical piece I guess.
I've been thinking about putting one on my 88. It gets hot around here in the desert to the point I almost need a "winter" tune and a "summer" one. With the IAT, I can adjust timing based on air temps, including heat soak on warm startups.
