Buddy did u take out both o2 sensors?

oh wait that wouldnt matter cause one u unplug the o2 sensor you will get a low cicuit bank one that will be a code that will put the car into limp mode. HEnce no power.

 

it really doesn't make sense for it to be a throttle body issue. its an A/F problem probably mas. but the fact that the o2 was taken out and nothing changed is interesting

 

I tried running it with the o2 plugged in but not in the cat and again with it completely removed.....still no difference in performance .......the maf reading at idle warm was 2.61g and my only engine code is that annoying brake booster vac intermittent failure thing. Would that mean anything? I can give you an autoscan if that would help

-thanks

 

Hi Iam new to this I've got a audi a4 1.8t s line convertable the problem is it will rev fine it will drive but soon as I put me foot down no power please help it' a 06 plate I think it' me egr valve just wanted to know if I was right thanks for reading

 

I sold my A4 but I think I ended up running into this problem before I sold it. The speed sensor went out. Another thing that fixed it, believe it or not, was changing the CVT fluid.
