Depends on whether you have a GEMS or a THOR engine.
MAF's are different and the ECU does not require resetting.

Sorry Zhoey should have listed 1998 4.6 hse GEMS I beleve I have orderd a new one from England so will see what go's on when I get it.

[zhoey]

GEMS is ERR5595 from memory. Yes, I think that's what you need. :)

My experience has included checking the Crank Angle Sensor. Sometimes they just loosen themselves off and become misaligned. You can pull them out and clean them up too. They are relatively easy to get at... do you have a copy of Rave?

You will get more ideas/feedback from forumites here... hang in there and keep at it.

There's dealers in Dubbo & Orange if you do get stuck.

Hi idle?
I would be checking the stepper motor as well.
At high mileage they seem to fall apart inside.

Hi Zuk, get yourself some soapy water in a spray bottle and go over all connections and joints to the intake manifold. Air leak into the manifold will cause the engine to idle faster. When you spray over the area that is leaking you will notice a difference in the running of the engine. Also check the PCV valve by crimping the air line from it to the manifold. Do the same to all other hoses leading from external components to the manifold. If there is a leak at an external component there will be a difference in the running of the engine when you isolate the line to a faulty component.
