As I said in my post, I replaced one of the sensors (even tested the new one, checked out ok), the one for the ECU. There are 2 more, right? 1 for the A/C and one for the... fan switch? Either way I dont think either of those would have a huge impact on starting. I definitely smell gas if it takes me a few tries to start it without much success... I almost think its probably running TOO rich. Don't have a whole lot of evidence to back this up though. What would cause it to run too rich?
I'm not getting any check engine lights.
I wouldn't be thinking much of this, if it weren't for the fact that it didn't have this problem last year, not even in -10 degree weather, it would at least idle on its own.
I've had the ECU out and examined it closely, no leaking capacitors. Maybe I should have them replaced anyway?
I think i'm gonna log it when it first starts and post it up here for input.
