I recently installed an aftermarket exhaust and headers package on my '03 LX470. Within 15 mins of picking up the vehicle, the CEL has come on (along with the VSC and VTC lights). Now, I haven't checked the code as yet but I'd bet my house on the 02 sensor after the cat being the issue...
need suggestions/help please!
I've read several dozen threads and tried lots of things - hopefully the solution is something easy
97 40th fzj80, with 183k. ive owned it for the last 20,000 miles or so, and it has always been a reliable starter- no previous issues. The truck was...
I'm kind of a newb to working on rigs, so hoping for some guidance from the experts on what I should check on my '93 FZJ80. I'm experiencing a rough idle and rough engine under load. It also feels like I'm down a bit of power, but I can swear by that claim. I'm not throwing any CEL...
I wanted to share my recent experience with sorting a trouble code 22 CEL issue I recently experienced with my 91 FJ80 (3FE.)
Basic synopsis of symptoms:
Extreme idle (2500 on the high side, 300 on the low side)
Trouble with cold starts
Trouble with hot starts
I've searched quite a bit for similar posts to my issue, but I cant seem to find anything that helps explain what I'm experiencing. I'm hoping someone can point me in the right direction or has had a similar issue they were able to fix.
The P0135 error is intermittent and can...
Though I have owned an 80 for close to 20 years, thankfully my 80 has been dependable so I haven’t done any diagnostics on it. The few CELs that came up over the years handled by shops like Iron Pig.
My troubleshooting skills, meager as the are, were rooted in the carburetor age.
Both of my...
Wife went to start the GX470 and the pictured lights came up and stayed on. Im hoping its the gas cap. unfortunately im out of town so will have to wait until my FIL can scan with OBDII scanner tonight.
Wife says no weird noises, voltage seems good, car drives fine.
I have noticed the gas...
This past weekend I experienced what I believe was a 'limp mode' instance, but not sure this can occur without CEL.
After driving approximately 90 miles in 95-100 degree temperatures at interstate speeds (75-80 MPH) with AC running front/rear, my truck lost power suddenly on the interstate. At...
Out of the blue, one day it would crank, but not start:(
No Check Engine Light with ignition key turned
Checked voltage through all fusable links: All good
Checked all fuses: All good
Checked voltage in under hood fuse box: All good
Replaced EFI relay
Checked voltage on interior OBD2 and under...
I have been at this for a week and a half and still can't get my truck running right. Here's what I did:
2. While I was doing that I accidentally broke off knock sensor entire connection
3. Installed new knock sensor, but sketchy old connector, Code 55 and no power
4. I soldered in a new...
It is time to beat another dead horse. Anyone with me? I hear its all the rage these days. Well, anyway, like the title says, I have been battling this problem for a while. I just cant seem to nail down what is causing it. It starting after I completed a head gasket job/desmog a few weeks ago...
My 91 has been f'ing up lately. At first I thought fuseable links, but I changed them and still the same! I have 12 volts to the underhood fuse box, but only 3.7volts at the B+ terminal in the firewall mounted test port........????? Any help would be great! Can't find it in FSM!
Uggggg!!!! Need good qualified Tech advice. And probably a good qualified Technician as well.
My daughter has a 2004 2wd 4Runner with the 4.7 V8 with 116k miles.

It's throwing CEL codes for the Air Injection Pump & valves.

New here and only owned a 94 (240,000 miles) for a month. I've done a lot of searching and reading on the forum but haven't found exactly what I'm looking for. My CEL went on yesterday and I think it may be because I didn't tighten my gas cap all the way. Is this possible? I pulled code 71 and...
Threw code 71 yesterday so I have been reading threads and taking things apart to see what's going on. Pulled my modulator and vacuum hoses to check for carbon and it was pretty clean. Might even be somewhat new based on how clean the little filter is. But then I turned it over and saw this...
I got a code 52 on my 80 and it mentioned the following
1] Left Knock Sensor Signal abnormal.
2] Knock sensor circuit fault
3] Senor to be tighten too close or too loose to the cylinder body
4] Ignition timing error
5] securing seat of generator or compressor loose
6] too large clearance noise...
Over the past few weeks I have been trying to fix my 1994 FZJ80. It first started with a CEL. I took it in to have codes read and pulled codes 25 and 26 (air-fuel ratio lean and air-fuel ratio rich). I replaced the O2 sensor and it drove fine for about 500 miles then the CEL came back...
Sorry for the long post. I really believe in providing as much info up front. I appreciate you taking the time to help.
I drive a 91 FJ80 with the 3FE. I am desmogged completely (no EGR/Cats/Air Pump).
I started having a trifecta of issues last weekend while on my club's annual ride.
