Hey all, been trying to track down an issue on my 1993 Land Cruiser with the 1FZFE. It has no power and is stumbling, sometimes will die if I lightly bumo the throttle at idle. Sounds like a diesel. I've been through the forums to no avail, so here's what I've done to it and what I've checked so far.
Had a code for IAT, so I replaced the AFM, the injectors were just flow matched and cleaned, replaced #6. The intake manifold was hot tanked and gaskets replaced, new spark plugs, wires rotor and cap were replaced about half a year ago with NGK and Denso parts. Distributor tested good. Ignition timing is at 3°, fuel pressure to the rail was within spec, pressure from the regulator was 60 psi which seemed weird to me so I tried a new one, I've done an EGR delete long ago. Compression was good in all cylinders (about 150 psi on all), valve cover gasket was recently replaced. The wiring loom where the EGR used to be looks good, no difference in idle when I wiggle it around.
I'm about to test my TPS, although that is a relatively new unit. Also the only offbrand part on my car .-. So I wouldn't put it past it to be bad. I haven't replaced O2 sensors yet, dunno how old they are but I dont think they would cause this. And my intake boot was cracked and i duct taped the crap out of it over a month ago with no issues, so those are my 3 culprits left. Then ECU. Any thoughts and advice would be appreciated as this is my daily driver
