Which portion(s) of the exhaust system should I focus on during a baseline? Are there any parts that are definitely replace after 150k miles? Or things that should be done preventatively?
So far I've replaced the PCV Valve and top two ventilation hoses which were both hard/cracked. I'll be...
I'll start this with, I'm still not sure I want to delete EGR, mostly because after I rebuild my engine from a cylinder 6 head gasket failure, I have to pass emissions ONE MORE time in Georgia before the truck is 25 years old and no longer requires emissions. I just don't want the extra headache...
My 93 FZJ80 is throwing the Code 71. After cleaning the modulator and replacing all the lines, I ordered a new EGR valve. My issue is that my new EGR valve did not come with the temp sensor hole, assuming it's from a 95-97.
Can I still use this valve and have a functioning EGR system? And/or...
I have a 1994 FZJ80 with the 1fz-fe. Looking in to a smog delete including egr, o2 sensor, etc. Cats are already removed. What all would I need to do these mods? Possible issues I could run in to? Related threads? How difficult would this be for the average guy?
Hey guys , I know there’s tons of threads out there related to these issues , and I’ve read about every single one of them trying to figure this out. On my 97 fzj80 I have the p401 that I can’t get rid of. I have tested the egr modulator, tested the egr valve , did the VSV mod using the dorman...
What type of hose should be used between EGR valve and carb(see yellow cap below)? Vacuum, fuel, etc. It appears to be around 5/8 diameter.
Vehicle is 5/1977 FJ40. Original hose appears to be NLA.
Did the PHH bypass this week.
Truck is 1996 with 200K.
Did not look to be bad, but unless hose is bulging I'm unsure what a failing rubber hose looks like?
Did the full Bypass with Gates (white stripe) and Breeze Constant torque eliminating the Metal Tube and both long and short pieces of...

I've searched but can't seem to come up with anything.
At highway speeds and mid- to high rpms (~3k), with very light throttle there is a loud rattling noise. It isn't at a specific rpm so I don't think it is a harmonic rattle of a heat shield or exhaust clamp.
A lift off the throttle or...
I have a new to me LX450. Had a 401 when I got it. The PO just changed out the VSV thinking that might be the cause. With it being out and exposed now, it helped me diagnose a little bit. EGR works fine if I draw vacuum on it directly (engine stalls). I ohm the VSV and get ~36 which is...
I have a 95 Landcruiser with 245,000 miles on it. I'm in California, and need to get a smog check. The CEL came on about 5 days ago, and I scanned it and it said I had a po401 code ("Exhaust EGR Flow Insufficient"). I noticed that the EGR Vacuum Solenoid had a green sticker on it, so I assumed...
Ok, straight from the dumbass files:
Cleaning EGR & modulator lines, stuck a cheap paper clip into this port - and Dammm I think a piece broke off inside this small port (driver's side, intake manifold).
Tried to find another paper clip like it to determine if size matched and if truly broke...
Is it possible to de-carbonize the system with a strong solvent and reinstall, or is it better to simply replace the parts?
I'm going to start with the temp sensor. Hopefully I can clean it well enough to re-use. Code 71 on a 94.
