I replaced both my cats and they looked completely clear of any obstructions, but they still produced a p0420.

For the sake of consistency, how are these temps being taken? At idle? with the throttle held at a cruising speed?

You said it's not throwing a code... what's the problem then?

On another note, if you do end up replacing your cat, its probably a good idea to do both. I dont know that you want a fresh downstream cat with a 20 year old one just in front of it, for obvious reasons. I went with walker cats on my 00 Limited(cali emissions) and it was something around 360...

ya know I honestly cant be sure. I dont have a temp gun right now to go out and check, but Im about 80 percent sure after replacing cats, that the difference is 100+ degrees for both cats. Wish I could help more.

I had a p0420 code a while back, and after changing the o2 sensor, I was convinced it was the cats. I found a video online where a mechanic explained that that the temp reading from an infrared temp gun should show the temperature before the cats to be lower than the temp just behind the cats...

So you're getting a new injector to replace that one?

Sorry, my post was a little incomplete... yes, replacing the cats cleared my p0420 code. I found a good mechanics video on YouTube where he showed a couple ways of trouble shooting bad cats. With the vehicle at full operating temp, he held the throttle at about 2500-2800 rpm, then used an...

GrassFed replacing the cats cleared my p0420 code, but nothing has fixed my idle issue. I replaced both cats with Walker. I've had them on for a little over 6 months and am super happy with them. They have a 5 year warranty and 90 day satisfaction guarantee as well.

If your issue is caused by the same culprit that plagues my 4runner, then it will still be present after replacing the cats. I had a p0420 code and replaced both cats after trouble shooting the o2 sensors, and doing some tests on the cats. I also thought it might be a MAF sensor issue... so I...

Thanks for posting this GrassFed. I've been talking with a mechanic about the problem I'm having, and he mentioned that he really thinks all signs point to some kind of air leak. Not all vaccum leak, but an air leak after the throttle body. Could be a bad intake manifold gasket or even a...

gunmetal 3.5" BS. I kinda wonder how those 5 spokes look in a 17" wheel on a small 4runner. they look great in a 35"+ tire size on larger vehicles ike LandCruisers and Lexus GX, etc. 17" might be a big large for the real basic wide 5 spoke design of the F5.

For reference, I have a 2000 Limited with Sonoran 1.2 lift and I've gone through the entire front end steering and suspension and replaced all bushings and ball joints/tie rod ends with OEM Toyota parts(with the exception of Whiteline LCA bushings). I'm currently running 265/75-16 Duratracs in...

I have seen that SCS F5 wheels in 16x8 fit 231mm tundra calipers... but has anyone had any problem clearing balancing weights? I wouldn't think they'd be that close, but I've read where someone said they had to balance their wheels without adhesive weight along the center line on the wheel.

Did the part number you purchased (86300-35090) come with the antenna whip?
