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

[PeterBergin at aol.com]

Cap, rotor, wires, plugs and wires have about  40k on them.   Look good and 
dry.  Started car yesterday no difference, am going to pull  codes today.
Thanks, Pete

Its possible, but I wouldn't 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

Well  thanks to VAG com... this morning I pulled the codes, there was only  
1.  
MAF.   I was actually kind of happy to see it.   So I went online (audifans 
marketplace to the rescue!) found one a few  hours away from me for a good 
price 
so I went to go get it. Came back  about half an hour ago, installed it and 
all 
my problems went away!  Idles great, no smoke, runs amazing, and pulls like 
nobody's business! I  am so unbelievably relieved.  It was cold so I gave 
it a 
little  temperature, and got to maybe 12psi boost and it was effortless and 
 
smooth as silk. Ill definitely sleep well tonight! Or maybe not...Ill  want 
to 
get up early and go drive it!
Thanks for everyones help, I  appreciate it. Looks like Im good to go now.

Here's a picture of the  patient. Its a 1985 UrQ with 3B that has all the 
RS2 
goodies. Therefore  Its painted RS2 Pearl blue. It has the tall wing, 
blacked out 
rear  lights, euro lights up front and sport hood. 

This was an 'in  progress' picture, you will notice its missing the drivers 
side  
windshield wiper, has the 5000q wheels on it (winter tires) with no  center 
caps, 
and the front grills for the sport hood arent clipped in,  they are just 
laying 
there. Thats all been fixed now (except the 5000  wheels, the sport q 
wheels wont 
go on till summer).  _http://maxboostracing.com/RS2UrQ.jpg_

Since you have  VAG--COM, have you checked Group 0 , the one that has many 
operating  conditions like load, intake air temp, RPM, TPS, etc? It is 
designed 
to  be read at idle and lowish RPM. The Bentley will tell you what the in 
spec  
ranges are for the various readings.

Your MAF may only be  slightly out of spec, which means it may only need  
cleaning.

Cheers,
Brady
