Hello, newbie here. I’ve been on the forums searching for this issue but can’t find it. If there is something out there, my feelings won’t be hurt, please send link. Well here goes....when the air conditioning is off, the car purrs like a kitten, absolutely no issues! Idle is at 1000-1100. However once the a/c is running, when I come to a stop or have the car in neutral she has a very erratic idle and then shuts off. I’ve read not having heat shield for the intake could send hot air, while the a/c is running, in that area and throw the MAF for loops. So I bought a MAP Rev 2 heat shield to aid in this issue. Installed it, took it out for a drive and the EXACT same thing is happening again! Again if there is a link please send.
