Sometimes disconnecting the battery for 10 minutes or so then reconnecting it will get rid of that loping. The reason being...over time the computer learns how to control the engine more efficiently than by using the preprogrammed defaults. Now that you've made this repair the engine is responding differently...those same learned parameters no long apply. Disconnecting the battery clears out the learned programming and starts you off from scratch.
