egr

I took my 95 LC 4.5L to get smogged, it passed every thing, but the EGR valve wont hold a vacuum. I replaced the valve and still it wont hold a vacuum, so I am getting a replacement. Is he doing the test correctly? its in idle when he attempts. if i remember correctly my 88 4runner had a...

Hello all. Continuing in my 80 series resto- Have codes 25, 26, and 71. Running lean, running rich, and EGR System. It’s worth noting the vehicle is running fine over all- no noticeable issues. Any advice on where to start?

I'm currently putting together a good intake and exhaust for my 40 in prep for a efi upgrade. But I got to the egr port and the bolt holes are really bad and I'm unsure how to fix them. I really don't want to replace the horn or even take them off. So I got to fix the issues.

Hey All, I'm tracking down a P401 insufficient EGR issue. I've followed the FSM to check for vacuum at the EGR valve during cold/warmed up at 2500 rpm as well as moving the vacuum line from the modulator to the vacuum circuit. I did not see vacuum at the EGR valve in any of those conditions. The...

Hello, Does anyone know the part number for the vaccum line/clamp circled in the picture below? Thank you!

I have read most of the forums on here. But none of them touch on what I’m dealing with. I own a 1995 Land Cruiser (with OBDII) If you look at the attached image, you’ll see my color coding trying to solve the issue. Green means I have tested it, and/or replaced it. Red means I’m getting no...

the hayull outta anywhere near my wires. I’m not worried about gas mileage or any other concerns. I’m just worried for my wires. Now that I’ve got that out of the way, has anyone simply cut the pipe down low (remove front left wheel and starter to get low enough) and fill the stubby leftover...

Help please. How do I remove top bolt on bottom end of EGR pipe? I was up until past 2am messing around trying to get this and am stumped. I just need to get enough leverage to crack it loose. I got the bottom bolt out with some long extensions from the wheel well with the tire out. I just...

Thanks for the guidance from my previous post. I'm hoping the generosity of the group can help again ! I completed my emissions check yesterday, and failed. The ECU popped four codes (with no CEL, maybe the bulb is burned out??), and I think I have a path moving forward One of which, is why I'm...

Hey All, I am well overdue for creating an account and getting more involved on the site! I have been reading and learning from the community for the last few years as I searched for and eventually found my ’91 LJ-78 Prado. I originally purchased the truck from @vintage_coc about two years...

Below is a wiring diagram for HDJ80, which I assume is the same as my 97 HDJ81. What I am looking for is the locations of the VSV (EGR) [3] and the Pick-up Sensor [4], as well as some info on what the pick-up sensor does. I know that VSV (EGR Cut) [1] and VSV (EGR Control) [2] are the VSVs...

Hi All, '97 LX450 w/403k miles and no maintenance history before 370k mi. It's been a great vehicle so far. I'm getting a: P0401 exhaust gas recirculation flow insufficient detected error, followed by a P0130 Bank 1 Sensor 1 error (details attached) Question - What are the chances that the...

Preferably local to DFW. I bought my FJ62 engine without the smog stuff and I'd like it back. I need, EGR, EGR valve, smog pump, manifold air injection rail, air injection check valve, silencer, and VSV's, air box hoses. I need the exhaust manifold as well as mine was welded shut. I don't need...

Just took out the EGR on my “92” 80 as you can tell it is packed with carbon. I haven’t seen the metal tube on any other egr’s before. When I get a new one will the tube be come with it? Thanks.

Hey all - it looks like the last yokel in here broke off or did away with the exhaust manifold to egr mating stud on one side. I’d really prefer not to wait days for a replacement — anyoneknow the thread and size spec of those things?

Looking for an EGR Modulator - 25690-61010. For use in a 1980 FJ40. Thanks.

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?
