Title says it all, idles ok and max rpm. All inbetween is unstable, no codes and sometimes a long start. Seems to help when try to wait with key on a longlong time for the start matter, does not help for revs
You might need these guys. Sorry, i know English probably isn't your first language, but the joke is there to be had. the word you were looking for is hunting. As for the problem, Sorry I can't help, not knowledgeable on isuzu engines.
You mean the engine speed is not stable??? CASE excavator CX330 has been installed 6HK1X model of ISUZU engine, but it has 02 types of ISUZU engine: ISUZU 6HK1X-QB ==> mechanical fuel system. ISUZU 6HK1X-YSS ==> Electronic Fuel System (Common Rail system). What type is your machine's engine?
Yes its a commonrail engine
