searched and couldnt find anything, may have missed it so correct me if i did.

ok, so the past couple of months ive been noticing after the car sits overnight and you start it cold it will fire right up run for 10-15 seconds then the rpm drops and it sounds like it starts to misfire, the car feels like it has a vibration for another 10-15 seconds then it clears up and runs normal. ive also notice now that it is getting hot out, that if i have to get on it (down shift to pass on the highway, 6-3 is normally when its most noticable) get on the gas hard it cuts out. i have no cel or codes, thought maybe my air filters were dirty and no, checked and cleaned my throttle bodies, flushed my injectors, and had the engine decarboned. none of these helped any. only things i have not done are change the plugs, or fuel pump.

any input or help would be greatly appreciated

 

my car has a slight stutter (barely noticable) and i just changed my plugs out, i would try that first (not sure of your miles) and possibly the ignition coils might be going bd

 

Hey midnight, I think my car is doing the same thing. I have a video but I don't know how to post it, I don't want to post on YouTube. It basically sounds like its about to turn off but then RPMs jump back up to it's whole warming up cycle.

 

MM thats what mine does. ive tried just about everything. ive only got 50k on mine. i have NO CEL codes, im a tech at Hyundai, and i have a friend whose a tech at nissan, and neither of us can figure this **** out. havn't pulled my plugs yet, ive checked everything else but those, ive re learned my throttle bodies, my idle, my vct actuators, just picked up a new 225 pump today im going to throw in it tomorrow and try.

 

put in new plugs, and new pump. the cutting out at wot is gone, but still seems to stumble on clod start. really starting to **** me off.
