S5 Tii Fuel Cut Hackjob and weird decel issue
#54
Could an exhaust leak at the turbo/downpipe flange throw off the readings some how? I have a pretty bad one at the downpipe gasket.
Clearing the codes and setting the tps makes the problem go away until I touch the accelerator with moderate pressure and it trips the check engine light and the surging idle comes back in as well as the hesitation.
I may be grabbing at straws here but I have no other ideas.

Well, I am unsure which harness was used. However, the issue is fixed! (mostly). As stated before, I noticed the BOV was set to vent to the atmosphere. This is typically a no no on MAF based cars, so I made a crappy plastic block off plate and the car seemed to run a little better. I then set about the task of making a recirculation adapter since BLITZ doesn't carry one for this model in the last 4 years :/
Went to Home Depot and bought a 3/4 ID piece of pipe that has a threaded end, threaded in a brass barb 3/8 to 1/2 fitting and attached a section of vacuum hose to the intake elbow.
Car idles much smoother, I just need to set the TPS one last time and lower the idle and it should be done!
I am still completely bewildered as to why the CEL keeps tripping out, but for now I am not that concerned.
