I DCed the battery before doing water inlet housing reseal. After reconnect the battery, the 4r misfired for the first time after Reconnect battery. and today it misfired one time again. they both happened when cold start.
checked battery terminals, checked the MAF sensor plug, they are both fine.
Does the ECU need to relearn everything and cause misfire possiblely?
the vehicle runs fine after it's started.
No CEL
