'87 5000 tqa check engine light = code 2322 = intake air sensor =questions

[Keith Lawyer]

I'm far from an expert, but what about bad gas?  Sounds like it could be that the car thinks it's detecting knocking?  My 200 had the same symptoms when I first got it and (like an idiot) ran 87 octane in it.

Sure, I've got one KS and you have two, but that shouldn't seem to matter necessarily?

Hi all - Subject line says it all. The problem is I'm on the road and don't
have my Bentley manuals with me.

Check engine light only comes on at about 1.1 bar and goes off if I take my
foot off the gas or go lightly on it. The car is chipped, pulls 1.9 bar and
if I hammer on it, I sometimes feel a slight bogging down or lagging after
the "check" light goes on (1.1 to 1.2 bar). Other than that, the car drives
and runs well. I only have the problem under load and only if I'm aggressive
on the gas pedal.

Pulled the codes, got 2322, "intake air sensor bad" or "intake air sensor
wiring defective." (I happen to keep a print-out of codes in the glovebox,
so the missing Bentley didn't slow me down here).

Do my symptoms sound like a bad intake air sensor? Where is this sensor?
(LOL!). Should I stop driving immediately until I fix it or just drive like
my mom, nice and easy?

I'm going to make some calls to check on prices for this part.

In the meantime, thanks in advance for all your help and advice.
