I dont usually start my car and go but today I was in bit of a hurry. Started the car and waited about 30 sec, started driving down the street, at about 2k rpm there was a hesitation (sort of a misfire) feeling to it. If you take it a couple of hundred rpm up around 2.5k it runs fine. Drove it til it warmed up than it was normal. Wondering if anyone else has/had this issue?

Has a tune but was done during the summer, now its -10 out lol IOWA
Would the climate affect it?

 

climate affects my car. in the winter like now if i just start my car and go it defenitly does not feel right until its warmed up. my car has done this for years now, to me its normal

 

for me it's like hitting a brick wall at 2k when cold. it either doesnt want to go past that with normal gas input, or give it enough gas to get past 2k and it goes like a bat straight out of hell

 

Im guessing its all in the tune. I went ahead and hooked up my buddys scan tool and checked the misfire #s. Noneof the cyclinders had a miss. Will try the injectors also. Could the intake air sensor IAT be faulty?
