i have catless dp's, fmic, dci, and a jb4 on my 08 335xi. Recently ive been feeling some type of stutter when driving and the idle has been a little weird. For some reason Autozone and a shop i took my car to get the codes read and figure out what's wrong.. but no one has been able to read the codes?!?!? possibly because of the jb4??
Start up the car and it has quite a bit of white smoke (live in Chicago so its cold af). Smells like gas a lot more at start up too.. and gas mileage has been going down.
When i step on the gas i feel very little power almost like half the engine isnt working. When i gun it there is no doubt ill get a check engine light. not sure if its spark plugs? fuel injectors? fuel pump?
Also, i have catless dp's if that makes a difference? i do have the SES light on normally goes away if i do a code clear. i have had 1-2 experiences where it cleared for a couple days but came back.
if anyone has any experience with similar symptoms id grately appreciate the feedback.
Thanks
