Hi. Just wanted to ask if you've encountered this problem with the car listed above A32 with the 3.0L VQ30DE V6 engine.
- Intermittently, idling drops then car stalls, but usually only while stopped, not while running.
- While running at low speed, engine starts misfiring (?) - sputters, revs jump up and down, and stepping on gas does not produce revs, so pull over and wait it out, or restart if it stalls
- Cleaned the fuel tank
- Cleaned the MAF and the IAC
- Still happening
Any suggestions? Thanks!

I would do a full tune up. This guide can help walk you through the steps, also I would service the throttle body and check for vacuum leaks.

Use this guide when the engine is cold only:

This guide may help as well:

We should run the codes as well.

Please go over these guides and report back.
