Hi.
I do have good used 1.9 air flow meters if that's what you mean by 'air
intake sensor.'
I find I have to check over about 6 to 8 things on 1.9 wbxr's , when they
don't run right.
It's common almost.
Some items I always consider and check :
Coolant temp sensor and its connections,
Any air leaks anywhere,
Throttle switch adjustment.
Air idle screw adjustment
Air flow meter CO adjustment screw
Oxygen sensor performance,
Anything to do with cat or exhaust system,
EFI wiring harness......'rarely though'
ECU - also rare but possible.
Ground connections everywhere.
The usual tune up items.
Spark plug wires.
Air flow meter
I've had to check, try other parts, clean and inspect and just mess with
them for quite a while to get them right again.

Subject: 84 Vanagon GL Intake Air sensor?
Hello all, my name is Chad I'm new to the list and to the world of vanagons,
i have owned many VW's but never a vanagon. so... i have some trouble
shooting questions.
OK here are my symptoms.
when i take off from a dead stop or just try to accelerate quickly, like
passing gear (punch it) i am "hopping" its not stalling, but lurching, and i
am gaining very little speed or RMP's. if i let back on the throttle a
little i lurch forward and gain speed...i can get up to speed but not very
efficiently and cruising is fine...the gear change is smooth (its
automatic).
i am also having some cold start idle problems that dissipate once the
engine has warmed up nicely...the guy i just bought the vanagon from told me
all this stems from the intake air sensor...and i would like some input
before i buy a new because they are difficult to find used and new they are
really expensive.
my questions are:
*does this sound like its the air sensor? or does this sound like something
more serious?
*will this harm anything if its not fixed promptly?
*are the idle and acceleration problems part of the same issue?
* if this is an air sensor problem can i by-pass the sensor? (i was told
there was a way but i don't trust the idea honestly)
i am sorry its so many questions at once.
thanks for listening
take care
Chad
