Getting the Wheeling Fever

There is another area that may be worth investigating. The throttle control. If yours is the same as my Trooper (4JX1 engine), it is "fly by wire" and not a physical connection.
I had a similar sounding problem last year. The problem, in my case, was the throttle body. The main agent did the work so I cannot help with any of the technicalities.

Please advise how you managed to over come this fault on your Isuzu.
Thanks and regards,
Roy Sinclair.

Roy,
I'm sorry but I cannot be a lot of help as I just let the main agent do the job. If I remember correctly, they changed the throttle body (or whatever the engine end of the throttle wire is called).

The throttle body proved to my problem - the butterfly valve position is detected by a small carbon potentiometer which failed. This thing would cost less than $3 to buy but you have to get the entire unit, which is factory calibrated, at a cost of about $800! Don't be tempted to fit a secondhand hand part!
