REVscene Automotive Forum - View Single Post - Q45t bucking in first minute or so after startup

My engine misfires and bucks in a warm-start or re-start situation (been driving for a while, stopped the car for less than 3 hours, restart)

and it would buck harshly at very light throttle input and at very low RPM.

Is it a common thing that happened to other Infiniti models?

Tried changing the fuel filter and sparkplugs it made no difference. It happens under a set condition which leads me to believe it's an engine management issue.

Any input would be appreciated.
