335i mysterious new problem??
last week i was driving and hit a hole on the ground. after everything went to hell. the car starting misfiring and apparentely killed the battery. so i had it towed to bmw they replaced the hpfp and upgraded the software. i brought the car home and it kept shuttering shaking misfiring you name it . i replaced injectors coils plugs and battery. now it only starts on cold starts after its warmed up it just cranks for a couple seconds. but when it does manage to fire up it still shakes and rpms still go from 500-1k. i try to drive it but theres no throttle response? i really need help its driving me crazy i had just dynoed the car the day before so i had added 3 bottles of nos octane booster on 7 gallons of 91 octane what can this be?? would really appreciate any thoughts

I've been super busy as of late. In the process of moving but if you have the jb4 I will help you select the right com port and get it communicating
