Need Help!! I have a 1991 Mu. Recently, when driving I seem to lose power in 3rd gear and around 3000rpm and it starts blowing large amounts of black smoke but sometimes it will suddenly take-off and run as normal. But when stationery and idling, you can rev past 3000rpm without any issues. If theres anyone out there who has any ideas where to start looking...I had a mechanic friend look already and he is dumbfounded...appreciate any suggestions. Dying to get my MU running for Summer.

Check your fuel delivery, filters, fuel put a dose of injector cleaner in the tank. Next step drain the fuel tank you may have a pick up problem. Oh another you may be getting air in the system, split hose etc. Hope you work it out. cheers Bruce

also when was the last time you had your injector pump serviced & injectors themselves? has the mixtures been tinkered with? is it just a one off thing maybe you just picked up some gunk?, have you tried tipping out whats in the fuel filter to see if theres any contaminents?. sometimes i suffer from poor performance nothing what a can of red bull cant fix (or 2)must be a bloke thing just my 2c good luck. muvit......

I've had same problem ; engine didn't rev above 3000 and if it did go littlebit over it loosed power. I've been driving it like that until injector pump blew up,engine stoped and wouldn't start again. $ 3000 AU, later with new pump and rebuilded injectors it revs as a sports car but it uses bit more of fuel too.
