IAC and MAF are suspects still. As is a dirty throttle body.

I can clean the TB, TPS, and IAC just fine. But... with the MAF being ultra sensitive, whats a good way of cleaning it?

If the car is running the boost gauge should either read vacuum or positive pressure. 0 would be read consistently when the key is on with the engine not running only.

I would expect the vacuum level to change when idle changes.

I asked him that because my car was behaving the exact same way when I broke the tube to the MAP sensor and it also made my boost gauge read zero. So I threw that out there since that does cause idle to act exactly as he described.
