Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there, do you have any codes?
Please check and let me know, because a couple of things come to mind when we see bucking on a cold engine in these cars.
First thing we want to know is if there is any smoking when it's bucking while cold, if there is no smoking rev it in park and see if the engine misses when not driving, but still reving.
