I've crossed over from the 80 side to try and shed some light on a problem. I have a 1992 fj80 with a 3fe. I have a really rough idle and also what another mudder calls the turbo effect, she has slow acceleration unitl about 2300-2400 rpm than BAMB it fills like the NOS button was hit (and no I don't have nitros or a turbo).
I've replaced all the vac lines, egr modulator, fuel regulator, egr vsv, radiator, fan clutch, alterntor, smog pump, belts, t-stat, fuel filter, fuel sock in tank, adjusted valves (although it was my first time in twenty years, so may have to look at them again), new intake hose from afm to throttle body, plugs, rotor, cap, wires, most radiator hoses, air temp sensor @egr.
I know alot of the above dosen't pertain to the issue, but I wanted to let everyone know what has been done so far. I've searched the threads and found numorous solutions but all have been to no avale. I've sea foamed the spit out of her, cleaned all the carbon off the sensors entering the intake plenum.
When I first got her about six months ago she was tired, bought her from a soccer mom in California, so she never seen the dirt.
After doing all the above she's running really strong except for the turbo effect and the rough idle. She's now sporting an ARB front bumper with a powerplant warn winch on used 32's. I have a used FOR suspension sitting in the garage ready and waiting.
Anyway that's her story and any insight would be greatly appreciated. I'm at my wits end and don't want to keep throwing good money after bad. I'd rather save it for some more mods.
