Runs better prior to drive cycle
2000, Ford Windstar, 3.8 liter.
For some strange reason, when I reset the PCM by disconnecting the battery for about 10 minutes, the van seems to have better power and smoother shifting. A few days later, after completion of the drive cycle, it seems to lose a little power and not shift as smooth. No codes being thrown before or after drive cycle. Any ideas???
