The computer has some adaptive learning modes. Resetting the computer removes any learned adjustments and restores the default parameters. This is a different than resetting any fault codes that may be stored in memory.
If there is not an active code (the 'check engine' light is not On), then there will be no 'limp home' strategies in effect, no matter which faults are stored in historical memory.
Not sure how much adaptive learning was done on our vintage of truck. At any rate, the computer should eventually re-learn its way back to where it should be.
However, pulling the ground cable off the battery for about 20-30 minutes effectively 'zeroes' the computer offsets, and hopefully results in a shorter, faster learning curve.
