S/4 convertible wont hold idle!
Yes ive searched and just found peeps having problems with 7's not holding idle but there problem is pushing on gas pedal wont matter,still wants to die.
MY vet starts just fine rpms go to 3k then will drop slowly (2-3 sec) to 2k then after that it drops radidly and then dies. She will idle wen i step on gas pedal and make her idle thats not a problem, also driving in gear is perfect, just wont hold an idle what so ever.
I just replaced the afm just to make sure it wasnt faulty wen the problem arrised, made no diff from previous afm.
Just eliminated the stock air box, all vacum lines on rubber pipe are all connected , replaced the o2 sensor 3 months ago wen i put on pacetter header.
Afm is not sitting at an angle its level and not upside down.
ben driving her for 3 months with pacetter header and main cat has good size exhaust leak, but never caused her to die, idled lil bit ruff but never came close to dieing out with the exhaust leak.
Tried to start her up today and engine was cold , revd to 3k then wanted to drop i held gas pedal about 10 sec's or so, she idled for about 1 min then then dies out.. I noticed my header was glowing orange is that normal wen engine cold?
any help is helpful

long story short: put on new intake , started fine idled fine , drove thru stop and go traffic for 20 min no problem , got on freeway drove for about 7 miles as soon as i took my exit i noticed that the car was off, thats it,.
After that the car would not idle for nothing...

i don't know if this will help or not because the symptoms are quite different. Everytime i braked hard, my car would shut off. it turns out something was stuck in my throttle body. took it out and car worked fine.
