I have a '99 boxster 2.5L, manual, 98,000 miles and after driving it home with no problems and parking it, now when I turn the key it cranks over like it's starting up but it will not idle and quickly dies. I can start it and feather the gas pedal to keep it running but it doesn't sound quite right and as soon as I let off the pedal it stalls. If I try restarting it again right after it stalls it then has a harder time starting and if I go for a third try after stalling out the second time it does nothing. I hooked it up to an OBDII reader and it gives this error code "P0102 MAF or VAF A circuit low input". I looked around on the web and whenever I saw posts concerning the mass air flow sensor no one mentioned their cars not being able to idle... I did see that sometimes the MAF error code is generated when something else might be wrong. Even though I read several posts where people drove around without the MAF sensor attached I still removed and visually inspected it (it wasn't even dusty). Tomorrow I plan to check the idle control valve, if that isn't it then I have no idea what to try next. I am having a hard time finding anyone else that has posted a problem online like the one I have and I don't want to be buying unnecessary replacement parts "willy nilly" to get to what's wrong, any ideas or suggestions are appreciated.
