so my s5 n/a is loping at idle. i havent found any vacuum leaks, sprayed carb fluid under the UIM nothing, changed BAC, AFM, TPS, TB, all gakets do do with intake air, adjusted TPS.
but everyone keeps saying vacuum leak (but theres none)
when i turn the A/C on it stops loping
when i start it it idles fine with the warm up sequence (3k for 17 seconds then drops onto the fast idle cam) but once it drops off the fast idle cam it lopes at idle.
can anyone suggest abything other than a vacuum leak (cause there is no vac leak)???????

 

Wrong section.

 

how do you figure is a s5 rx7?

 

s5 is second gen, this is the third gen section..
