So this issue was kinda like one that pissdrunx16 is having here.
http://teamzx2.com/showthread.php?t=9101But its now unique to me, since replacing my IAC did nothing.
So to recap, when I’m at a stop light, the idle drops to 900, then keeps dropping till the car sputters. She doesn’t die, and if I turn on the temp controls the idle shoots to 1,300 or so then drops back down to the problem area. After a bit I get a P0171 CEL. I’ve been checking for vac leaks, though not done with that yet. I’ve made sure the PCV valve is plugged in (the valve itself was replaced like 8k miles ago) and I’ve tried installing a new IAC. I’m about to pull and clean the TB and it was also suggested I look at my crank sensor, thou I have no idea where that is.
My other thought is do I have a fuel sending issue? I mean if the engine is running lean can’t that be caused by a fuel shortage?
