Ok....I have a 1994 eldorado, which i actually FINALLY just got today, even though i joined this forum about a month ago.
With everything I learned from reading while I awaited my eldorado, the very first thing I did was check my codes by pressing the off and warmer buttons.
If I understand correctly, I received no recent codes but four codes in the history, being SO10, SO13, SO44, and SO63, then the computer stopped at the signal "PCM?" And did not know what to do from there.
Anyway, I have noticed in driving the car, there is a slight, slight stumble/roughness as I press on the pedal while in park, between 800rpm to around 1000 rpm, then its smooth thereafter.
The only other thing I noticed, is a slight, but not every time, jump into first gear from park, and occasionally a slight jump hesitation going from a stopped position to driving.
If anyone could suggest anything I would appreciate.
Thanks in advance,
