so when my car is cold my acceleration is choppy like is breaking up almost like my 2steps on ,but even turned it off and i get the same problem. So today when i was on my way to work engine was cold i want to get on the highway half throttle, got super choppy like a miss started to pull bout 20psi and engine light started to flash got off the highway turn the car of then on light gone smooth pick up. Any ideas but when its warm it pulls hard and smooth plz help

 

Sounds like spark issues to me. Maybe check your plug gaps or get fresh plugs?

 

I had a semi-similar problem to yours, although I'm not nearly as modded. People on here simply said "you have to let it warm up" but I ended up switching my spark plugs and it ran like a champ ever since.

I see you are running iridiums on a ss/sc... I would definitely switch them to coppers and gap em for a 2.8

 

i have v power ngk in my garage idk if there cold enough BKR6ES?
my plugs look good but im just gonna change them any way .032 gap sound good

bump i need more advice
