ISUZU TROOPER SPARK PROBLEM

1990 Isuzu Trooper • 176,000 miles

Just did put in new spark plugs and spark plug wires. Changed the air filter, and did an oil change. I must have bumped something out of place, but I do not know. Now when I switch gears, if the rpms are not over 20, it starts to bog down and die.
When I replaced the spark plug wires, I did them one by one, so they are still firing in the correct order, as well as tightly plugged in.
What's wrong?
