When I start up my car whether it be after 1 week of sitting there or 5 minutes after my last drive, when I start up the car it starts up rough and boggs for like 10 seconds then goes away. I changed out the plugs, but have not changed the coil packs cause I changed them like 20k ago. I tried some Motul Fuel Injector Cleaner, and it ran good for 1 day, then it came back. When I run it after the bogging goes away I have no problems.
Car is Turbo charged, I checked all the hoses and mnade sure everything was hooked up.
Has anyone else experienced this?

 

I may have or may not have experienced what you have...cause it has only done it maybe once.

Although, if it was a vacuum leak, your idle should of been higher, and probably irregular, not low, and bogging like.

 

did you fix the problem?

 

sorry rong post

 

Could it be in your tuning? The car could be running too rich at cold startup.

 

greg.. your car is dying hehehe j/k
i ran into this couple times when i start the engine, but mine goes away after a sec.... with a loud vacumm noise....

 

yeah, it goes away, but I wanna find out what it is, Took it in today to check alternator cause I know another member who had the similar problem, but battery, starter, adn alternator are all good gotta go backwards now, changed plugs, gotta check the coil packs, and the injectors

 

isnt this caused by the map sensor?

 

well I swapped around the coil packs, took out the plugs inspected and put them back, and it starts up great now, no problems. Weird. Glad it went away but kinda worried as to what it was.

 

Could either be your secondary air pump, or a blockage in one of the air lines to the TB. The pump runs for 1st 10ish seconds after startup, then switches off (you can hear it whine down)
