hey ive posted before and havent really got the help i needed but i just want to keep trying to see if anyone new sees these.
anyways i have an a4 fwd 1.8t with remus exhaust and apr chipwith about 95k and if i floor it at about 3-4k rpms it bogs out and even at high rpms you can hear and feel it backfire.
it just began to happen. i think its my sparksbecause ive been running a couple different octanes once in a while but does anyone else have any other ideas.
and i also wanted to know how do you know when your turbo is out?
my turbo doesnt kick as hard as it did before and it sounds like its leaking. everytime it wraps around is sounds like something is hanging on it. hard to explain.
thanks

 

Possible boost leak.
Spark Plug gap wrong.
When did this problem start?
Any codes?

 

well my and my dad just did timing belt and water pump a couple months ago and we swapped sparks at the same time and there werent any problems with bogging.
but my and my friends like to run em a lot and my car wasnt running the same and then after i realized about the bogging.
another friend of mine has that thing to run codes but it wont read, it says error??
arp chip maybe?

 

is the timming marks lined up right?

 

you should check it again to make sure. Thats where I would start

 

yea we did timing belt a couple months ago and right after it ran perfect, no backfire or anything

 

have you upgraded your dv or you running a stock one?


if it is stock, the diaphragm migght be torn

jjust get 710n

 

when i bought it the guy told me he had a hks hybrid bov
i know there bad and ive been wanting to take it off and swap it for a dv but i dont know where its located.

 

Hi guys. This is my first time posting, but here it goes. I have a bone stock 5speed 2000 A4 1.8t. At low rpm... Actually any rpm really, it bogs out and backfires and I lose a great deal of power. The CEL is not on, but it is very irritating and sometimes dangerous as I would be turning in an intersection and the car won't go anywhere. I literally have to rev it up and then come off the clutch a second time to get it moving. Please someone help me!
