Oh, and congratulations on your engineering degree and good luck with your first engineering position.

Hello everyone, I know I've been inactive for some time now and just wanted to check in. I have not given up on this thread or my car but money and time has been very tight for the past year or so as I finished up my fifth and final year of my engineering degree. I've been offered my first engineering position and I'll be going in on Monday to do paperwork and make it official. This means I'll have adequate funds to spend on parts my car needs (while saving up for a low maintenance commuter). I had a couple notes on how my car has been running as well.
Firstly, for the past year or she has been the most reliable she has been for the past 4-5 years. I haven't been stranded anywhere, had any stalls at stop lights or slow corners, and she started up pretty easy every time this winter. While I primarily walk to class and drive my girlfriends car (2005 Accord) when necessary I've been making it a point to take the Mercedes for a drive at least a couple times a month. I also haven't had to change spark plugs for quite some time now, where before I had to change them every few months.
That being said, my fuel mileage has dropped. Prior to adjusting the control plunger / duty cycle I was getting around 19-20 mpg, now I'm getting 13-15. This makes sense after enriching the mixture and isn't really an issue as she's not a daily driver any more, but I thought it noteworthy. Also it seems to me there is a substantial amount of unburnt fuel coming out the tailpipe at idle but no notable smoke. Again, this makes sense with our diagnosis of a correct fuel / air mixture but insufficient spark. Luckily where I live emissions tests are not an issue .
I have had a just a couple hiccups. The situation goes about like this: After driving the car for a bit and getting the engine up to temperature I stop for 5-15 minutes and get out of the car. I crank the engine a few times and she seems to want to start but not quite be able to get there. I pop the hood, take off the air filter housing, and depress the AFM. It smells strongly of gas, so I prop it open in the hopes of letting that air / fuel mixture flow out and fresh air flow in. After a few minutes I replace the filter, try again and she starts up again without a fuss. I've had this happen in warm dry weather as well as damp cold weather, and it only happens if I stop for just a few minutes. This has only happened 2-3 times. I suspect it has something to do with having to depress the throttle to start the engine.
I've noticed my car goes through oil pretty quickly. I don't necessarily suspect it's burning this oil as there's always a some left on the ground when parked overnight. I've also noticed on very warm days (90+ F) when I come to a stop the oil pressure drops pretty low regardless of how full it is. Sometimes this is right around the 0 mark. Is this something to be concerned about? I've switched from generic 10w-40 to Delo 400 15w-40 after reading some recommendations on this and other forums. It hasn't been long but it seems like it's losing less oil so far.
My air conditioning and heating is fickle. Still, the heat and AC only function correctly under 3000 rpm. Sometimes they don't function at all, and sometimes they will only function after driving the car for a bit and restarting the engine. In the past 18 or so months. I replaced the blower motor recently as well as replaced a leaky air conditioning fitting. When doing so I was working with someone experienced in automotive AC and he suggested the heating / AC controls were vacuum controlled. Therefore with my vacuum leak it would make sense that they don't work at high engine speed. Heating and AC is of course lower priority than getting the engine running properly, but I was wondering if the AC is indeed vacuum controlled or if anyone has had a similar experience. I know the locks are vacuum/ air pressure controlled as when I first got this car they wouldn't lock and had to be taken in to the same questionable mechanic I previously mentioned. I've yet to inspect his work on that.
I'd like to thank everyone for the progress I've made with this car, especially @H.D. This car probably wouldn't still be running without this forum. I apologize for once again disappearing and returning with a massive information dump. I'll be re-reading this thread as well as the linked informational threads to catch back up. I hope to be more active on this forum and with my car now that I can actually afford parts.

I've been using it more and more lately to prevent / cut down on corrosion of contacts and such. Used on battery terminals there is almost none of the white crap build up that eventually causes electrical problems and "no starts"
I've also been using dielectric in switches I "rebuild", greases and cuts down on corrosion inside
