After using the search, I still haven't found any topics that could point me into the right direction, so I'm going to go ahead and post my plea for help
First, the CEL. It's an odd story, basically when I start the car, the CEL is off. After driving for about 20 minutes (could be 5 more, or 5 less, but always after a reasonable amount of time) the CEL comes on and stays on. Whenever I stop the car, turn it off, and start it again, the CEL is off again. Only to come on about 5 minutes later.
Does this sound familiar to anyone? I don't really want to go and get the codes pulled because over here (the Netherlands), they'll charge you $bigbucks just to do that, so I hoped maybe someone recognises the symptoms and knows what that is. I've got a hunch it's either something with the EGR valve, or the O2 sensors in the exhaust, since it only happens when the car (apparently) is hot.
This brings me to the next item; sometimes when it's cold outside and the car has been sitting for a day or so (think around freezing temperatures), it has a tendency to stall out when I'm stopped at a light. It idles on the rough side, gets rougher, and it stalls out. No lights come on prior to this, or during the stop. I've had this problem once before where it'd do it anytime I'd stop, and then slowly step on the gas again, it'd stall. If I just floored it (or at least pulled away "Aggressively") it didn't have this problem.
Again, I don't really want to take it into the shop, since this sort of stuff usually takes a while to find, and even tho the shop I go to is real good, they also charge for being so damn good.
If anyone has any hints, tips, or tricks, I'd be grateful if you'd share them
I'll warn you in advance, I'm not a real DIY guy, but if I've got enough diagrams and information available I'm always willing to give things a shot.
