Title: MISSING !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Post by: Firecop119 on June 26, 2010, 10:29:28 AM
hello   i need some help :flag_of_truce:  i started up my 1990 yesterday and it didnt run right. it idled just fine but when i hit the throttle it kind of has a sputter. when im riding it still sputters and has lost some power. theres not much power while taking off at a dead stop. when i ride it seems like it wants to clean it self up but just doesnt make it. 2 days prior when i shut it off it ran perfect and now this. the carbs were all rebuilt this spring and a new filter.  any idea would be great.   thanks all       :drinks:

Check your battery and conections. FJ's dont like to run at low voltages. If its an older battery I'd start there for sure..

Shit in the fuel, weak battery, float stuck up, kinked fuel line, very plugged fuel filter, old plugs, bad spark wire/connection, loose carbs, stuck slides, dying fuel pump....

Plugs and battery would be my first suspects.  After air, gas and oil, that's what the FJ consumes the most of!
