Poor running 3B

[James.Pasqualoni at sungard.com]

Just a suggestion-CRC makes a MAF cleaner that is a bit more hospitable
to the MAF than brake cleaner.

I would clean the connections (you probably did already), also my audi
tuner friend says he has treated them with brake cleaner, spray the
thing down inside a ziplock bag I think it was, and swish it around once
you have a lot of liquid in it. This seems to work especially well for
those maf's that have been corrupted by improperly treated k&n filters,
buildup of oily residue on that fine wire I guess.  Don't know exactly
what brake cleaner he was referring to.

Also pete, that radio should go out tomorrow, good luck

Pulled the codes today, the old 2121 kept repeating itself (used to
have 
an intermittent light) cleared the old ones.  All I get with the  motor 
running is 4413 (fuel injector 3) continuous, repeated its self at least
25 
times before I turned the key off.
 
Did the manual engine off click and buzz test, everything fine, felt and

herd 5 clicks on all injectors, any everything else clicked as normal.
 
Car cold starts fine, once I give it gas it hesitates and misses, only  
takes gas if I apply the pedal very gently.
 
Unplugging the MAF makes no difference in running, no worse, no  better.

Should I be looking for a used MAF.  If so any one have  one.
 
Looking for a way out of this with out going to the shop or replacing a

bunch of stuff I don't need.
 
Any Ideas?
 
Thanks, Pete

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
