1991 buick centry 3.3 has code 26

What is your question?

How can I figure out how to fix the 26 quad driver module A error, it runs ok at cruising and not on the gas pedal much, if I give it more pedal it starts skipping and running bad. Just replaced the tps still no better

What makes this problem better or worse?

When over drive kicks in it runs on all six, give it any more gas it skips bad. Has new ice new plugs and wires and tps

How long has your 1991 Buick Century had this problem?

More than a week
