Poor running 3B ---FIXED!---

[HJS]

Its possible, but I wouldnt condemn it yet. You mentioned ice storm and rainy... 
how old are your wires? how about the cap and rotor? Id pull that and dry them 
off first and see what that does. If they are new and decent then you might be 
looking at a maf. When my MAF went it was pretty smokey at idle and couldnt pull 
any boost at all. not even 1 psi

 Think you jinxed me!  Was driving home in the worst ice storm I have  seen in 
Minneapolis.  Car suddenly starting running like  crap.  Bucks, wont usually 
idle unless I hold the peddle down a  bit, must accelerate very slowly to make 
any  speed.  Bummer!
 
Car ran perfect before, however had two intermentant codes.  O2 sensor  and 
ISV.  Have had an O2 sensor on order, first one came in wrong  part.  Did not 
pay much attention to the ISV because the car ran perfect  (238k miles).
 
Unplugged the MAF sensor, no difference in car running, pressured  turbo and 
vacuum system to 15 psi, no leeks, pulled and cleaned MAF, no  difference.
 
Started to rain again (have to work out side) so I quit for the day.   
Will clear and pull codes tomorrow.
 
Think I am on the right path with the MAF?
 
Thanks
