S4 Turbo II.

When I drive the car under 3000 rpms at about 1/4 to 1/2 throttle it bogs down and wont go and i have to feather the throttle sometimes. It happens especially on hills. I changed my fuel injectors, and adjusted my Tps but none of those fixed it. Also revving it at low rpms it goes up slow, feels like no throttle response. After 3000rpm it seems to go fine. Also my Tps at WOT is at 6.7ohms.

 

Bump! Same problem. Help?

 

yea anyone im havning this problem too.

 

bumpady bump <-------------------got the same problem....

 

Have you done the "TB mod"?

 

damn I have the same problem too

 

It's just the design of the 13b. Ease off the pedal and it accelerates better. Too much wind velocity will lean it out perhaps?

 

stock ecu issue? Stock ecus run a bit rich from what i heard. sounds like your cars arent tuned right or something.

 

Yes some one has to have a solution sounds like lots of fellow fc owners are having the same issue....

My issue just started happening after i pulled engine to paint my engine bay. Did the rats nest removal, ran absolutely perfect b4 i did this..

Checked and i hav no vacume leaks, could this be a grounding issue? Tps is in working order per fsm.

Bogs down at full throttle, and hessitates (bucks) wen starting out from a dead stop, have to ease the pedal to get going and stop the bucking..

if you pulled the engine then your gas probably went bad during the time it took you to do your engine work. my car bogged at low rpms when i had bad gas i put sea foam in it and used higher octane fuel and it ran great.
