Maybe it's not what it was before. That leaves only one solution...

Could be isc.

Agreed stuck or broken, broken vacume line or unplugged, or leak in an intercooler pipe. All 3 of these allow un-metered air around the MAF and can cause idle issues.

I should make a list so I can copy/paste it into these types of threads.

Engine codes? Checked for vacuum leaks? Everything hooked up correctly? Is the ISCV functioning properly per the TSRM? Is it out of gas?
