Hello, I have some trouble with mpgs, idling and acceleration on my Wrangler YJ 1995. 4.0. Recently went to a mechanic, he connected my PCM to a DRBIII scantool, and he told me that the adaptive factor is -80%. He did reset all adaptive memory, and I can feel improvement in mpg and acceleration. Is there any way to reset adaptive memory other than connecting it to a scantool? I've read on internet about touching positive and negative cables (or grounding postitve), that it empties the capacitors in PCM adaptive memory. The reason I'm asking this is because I don't have scantool available all the time, and that this error is due to a bad LPG map (I have converted this JEEP to propane).. So I would like to once again reset memory, and after PCM relearns to copy that map to a LPG controller so there would not be any differences.
