I'm usually the one giving advice here but I need help from the true experts and those who have gone through this. My car (S70 '98 T5 with right at 110K miles on it) had been running great lately. Recently I changed a thermostat...no problems. Cleaned a replaced the PCV hoses a week or so ago...no problem there...and it was now time to do an oil change today before our semester begins at school tomorrow. I bought 6 quarts of Mobil-1 synthetic 5-W30 as I normally would for the winter and did the change. Strange, but I'm a bit short to the top of the dip stick so I decide to drive to the autozone (just a couple of miles away) for one more quart. Seems that most always I've got a smidgen left over from 6 quarts, but anyway, I get on the road. All is fine until I get off of our hill and onto the flat 4 lane. Then suddenly my car dies in the middle of the road. I try to start but it's a no-go. I try again and it barely starts and I get over into the center turn lane (just a few blocks from the A-zone) with my flashers on. I have my trusty scan tool with me so I look up the codes (check engine light on now), and at first I get P0243...Turbocharge Wastegate Solenoid A Malfunction, and think this is strange. Then, I get a second code- a P0103: Mass or Volume Circuit Low Input. I start up again with a great deal of effort and buck wildly to the A-zone who can't help me a bit...well, at least I buy an extra quart of oil and call my wife. I'm thinking that I'm going to have to park the car here over night but don't like the idea of it being messed with and want to get it home...so, by the time she gets there I've cleared the codes and can start my car again but it's very very uneven. Black smoke from my exhaust and smell of the cat. converter (sulfer), but somehow I limp home, the last leg of it up a hill, but the car seems to idle high...I think, that's okay because when I put on the brake the idle dwindles and the car will die. I let it do it's thing up the hill and into our driveway (just a half miles or so at most), and park my car. My wife is behind me all the way and tells me there was very little black smoke except once on the way home, in the middle of the intersection, at a red light when the car died and I had to crank it several times to get it started.

At home I get on the boards and read that most likely it's a MAF sensor, so I do the BAY13 trick of plugging and unplugging it 20 times (maybe a coroded connection, I thought), clear the code and the car start up fine. I'm thinkingt that maybe this fixed it, so I try to pull out of the drive way and up the incline of our coldasack but it stalls again...I back down and park it again, not wanting to do anything else tonight. I haven't touched the car since this...I don't want to. I'll probably have it towed to my indy tomorrow while I borrow my father-in-law's car to get to and from work. I can only do this for a day or two...I really need my car running right, and quickly.

Guess my question is, is this most likely just a MAF? The plastic tie around the connector (a fix that Volvo recommended a few years back) had been done when I bought the car, so I know that the original problems people were having is not the current issue. I think that the Turbo code was secondary to the P0103, but could it have been the cause? Did driving my car home foul up anything...the O2 sensor, Cat. converter, plugs? No other codes are showing up now except for the P0103 but the inside of the car has a distinct sulfer smell to it. Will changing out the MAF sensor take care of my problems or am I in for other stuff too with this code and what I did to the car after I got it (namely driving it home). Any help would be appreciated.

I suppose that trying to drive it to my indy tomorrow rather than having it towed is out of the question...right?
