My first post, so take it easy on the new guy.
1. Bought my wife a 2000 LC, now has 318,000 miles, runs perfect, rustproofed, did all scheduled maintenance, 3 timing belt changes, 2 front wheel bearing changes, 1 rear wheel bearing change, 2000 to 2004 oil & filter was mobil 1 & synthetic, oil since +/- 2004 oil changes I have added 1 quart of lucas, balance mobil 1 oil & filter, runs awesome, just drove it to alaska and put 10,000 miles on it in a month. toyota shop loves the rig, its dry, engine always detailed, used Fluid film for last 13 years to keep corrosion at bay.
2. Have a 1970 FJ40, 3 speed, +/- 90k original miles, runs awesome
3. Have a 1976 FJ40, 4 speed, +/- 96k original miles, de-smogged, engine had to be rebuilt after failed Holley carb swap poured gas down a couple cylinders, now runs awesome
4. Now the 92' saga, bought on ebay, spent $4k to service, rebuild trans, etc at 294k miles.......it was the tank that my 2 boys safely drove in high school and younger drove in college for 4 years. It now has 356k miles and needs some love. Sorry Im nostalgic. did a 4" OME lift, original rims and biggest BFG KO2's that would fit on a 15" rim.
The engine starts great even in subzero winter temps, engine runs great, idles great, no stalling, no backfires, no quitting which gets me past nearly all the troubleshooting pages in the repair manual. After reading through the entire repair manual I dont know what I'm missing. The exhaust pipes are ceramic coated & wrapped with fiberglass, valve cover & many other engine compartment parts have been powder coated last fall to enhance the rebuild. New hoses for radiator, heating, power steering, etc....
I'm at the end of my rope with resolving these codes. I have replaced the fuel injectors, caps, o-rings, fuel press valve, new fuel filter, new radiator cap, new radiator, & fan blade & Shroud, rebuilt power steering pump, replaced all the thermostat temp sensors, thermostat, replaced #2 VSV, new vacuum modulator, swapped out the EGR valve with clean one(may or may not work), installed new vac/air tubing with new spring clips, used specter off-road BVSV valve, etc......over the last 3-4 months and +/- $2000 in parts. The local repair shops look at it and say they can't help to save my sanity.
Installing and verifying that all the vac tubing/routing was correct from carelessness of shops over 32 years of service took time and found the P & R tubes had been reversed for a long time + resolved other issues. using caps and an air compressor was the savior to properly ID all the steel tubing passages without having the remove the intake plenum, etc....
Engine runs strong, trans/xfer case/axles good, body/interior good. Have been running lucas engine oil treatment, 3 quarts per change with mobil 1 filters......engine is dry
I have gone through the toyota repair manual and tested parts where needed, could it be the fuel cap or fusible link? those are the only old parts left on the rig!!!
Any help would be greatly appreciated.
