ok i finished my swap a few weeks ago and noticed a few funny things going on, first a got a CEL, checked it, no codes came. for info i got a skunk2 chipped p72 ecu. thought maybe it was from the chip. well after driving it hard for a few minutes, the car stutters a bit. came to a stop and launched and as soon as i hit 5000rpm, the car bucked, almost like fuel cut off. took my foot off the gas and put it into neutral to see if it was gonna die. no, idled normal. drove it home and was fine. the next day i drove it a bit and it did it a couple of times. took it to a dealership, they thought maybe my ecu. so whatever i drove it around later that night and it didnt happen again. and hasnt since. would this be caused by the ecu you think? maybe doing a learn of the motor? i have heard from some people that maybe that could be it but those people are all toyota people and nissan so..... any help on this would be great
