X585 Pop and surge

Kaliburz · Jul 31, 2004

Well, depending how big the fuel tank is, I say empty it out, flush w/ clean fuel. If you think your supply (transport) tank is dirty, put some fuel in a jar and let it settle to see if there is dirt.

Wait..... this thing doesn't have a fuel filter????? Dirty fuel "should" be filtered before getting to the injector..... /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

Actually it does. The dealer has ordered a new thottle body and will be here this week. Hopefully that fixes things.

I have a 2003 X585 with about 60 hours that recently started to surge intermittently. Several visits to the dealer have not located problem. Curious if anyone else has been able to locate the source of this problem.

Boy this was an old thread. I guess I should give it some closure. Don't know if this is your problem but the trottle body was the culprit. It appears that the valve was sticking or had high friction which caused the problem. No problems after they replaced it. This could be a chronic problem with the EFI throttle body or maybe a bad batch?

Same engine, same problem. Got worse with hours. Changed injectors, EFI controller, temp sensor specs out. Checked out throttle body, it looked ok, but didn't replace.
