Yeah that'* good news, I think, My 4runner did this at start up but it did smoke until it got warm. It ended up being the head gasket. I know the Ford 3.8L V6 is real bad about this too, only reason I ask.

No clue, I have never experienced one breaking down on me before (did have a bad ignition module recently). I would think the heat would make it worse.

Samething with my 4 runner, ran fine after it was warm. But your not smoking so hopefully that'* good news.

How about this.... How much coolant and oil has it dumped?

I'm still leaning towards the MAF sensor..... That is, if it cleans up a bit when warm.

CRC now makes a MAF cleaner spray, ive used it and it seemed to work well, just tossing that out there, eaiser than a qtip

I don't beleive the Maf is used during closed loop (cold) running, I'd be more inclinded to think its one of the temp sensors, if not the cap & rotor, leading the computer to think its already warmed up. A self-diagnostic (KOER) will give a basic test of the other sensors leaving you with just the two temp sensors to check with a meter.

As for cap & rotor, always try to use motorcraft; they seem to seal the best; although in a pinch I've used the gold series from AZ with good results.
