Mark,

You have to have it. The airflow sensor has a flapper inside that is
displaced when air is pulled through. The displaced flapper moves a wiper on
what amounts to a rheostat and the changed resistance changes a voltage
that's fed to the ECU, telling the engine how much air is coming in. Without
the part plugged in it may idle but it won't run.

I know a lot about the J-Jet systems but not a lot about the K-Jet systems.
Maybe Benny or someone else who works a lot with the K-Jet system will read
your update and respond right away.

Thanks,

Hi again. So, I checked a few things.
-idle stabilizer control unit contacts are clean, no moisture
-Idle control stabilizer valve is humming.
-throttle valve switch is NOT working at idle but working at full throttle
-WHEN HARNESS IS REMOVED FROM AIR FLOW SENSOR THE ENGINE IDLES SMOOTHLY.
When the harness is reattached it drops revs 200k, and gets very rough and
stumbles badly when throttle applied.
Does this tell you anything. Can I drive it with the afm unplugged?

Mark

Hi. Help needed. We are stranded at Homestead, Florida, where Hwy 1 heads
into the Keys.

91 GL Westy doesn't want to go any further. Started rough this am, but ran
decent most of day once completely warmed up.

Just completed 1700 trouble free (till now) miles on new fuel injectors,
fuel lines, plug wires, plugs, cap and rotor. Fuel filter has about 2-3k on
it. Checked plugs this am, and they were a brown and dry.

Now  just fueled up, and will start, but spits and burps, and can't get all
cylinders firing on start up. Feels like a lack of fuel delivery to me.
Getting more and more rough on start up last couple of days, actually since
some heavy rains a couple of days ago.

Suggestions on root cause or things I should check please, and does anybody
know any techs around very south florida that I could track down???

THANKS.

Mark & Mary
