what should be the gap on the plug anyways.
.039-.043. If the car is stumbling then reset the ecu and drive it for a few days. When the car stumbles below idle don't correct it with the throttle. Eventually the ecu will learn to not let the rpm drop below idle. I just did that a week or two ago and my engine only stumbles when my a/c is all the way up and it's 90+ degrees outside. It takes a few days for the ecu to learn how to do that so be patient.
