VR6 slowly dies at idle

[b0k1]

Hey guys, just started experiencing this problem today. Only thing I've done to the car since it started was cleaning the interior. Went to the shop today and I guess as the car warmed up I stopped at the lights and my idle started slowly decreasing until it died. Turned it back on and kept driving. Was fine for like 2 stops then got home in the garage and same thing happened.

So far I've cleaned out the intake and TB as well as the maf sensor. Does this sound like a bad oxygen sensor? When I removed it a while ago I used WD-40 to loosen it up and I'm thinking this might have damaged it. I have no check engine light btw. When I accelerate in neutral and keep it steady at certain revs it will just decrease slowly on its own. As I was driving I got up to 3k revs and it lacked a lot of power, it kinda just sat at 3k revs for a bit before increasing again.

It could be a fuel issue? Although I've never experienced this problem.

My little 1.8 was doing some strange things in the extreme heat today too, stalled a couple of times just after starting and seemed down on power, maybe see how it is tomorrow? Ofcourse these cars shouldn't do these things, but if it only happens when its really hot which doesn't happen all that often I wouldn't worry too much about it

I'll give it a go tomorrow when it's not 40 degrees, heh, I hope you're right!

disconnecting the battery fixed it right up.. I guess it reset the ecu and now it's fine. Not sure what caused the ecu to change it's air/fuel ratio or timing so drastically.
