I may be in the market for another 100 series, but I'm limiting my budget to $20k. If you come across one or have one worth a look, I'd be grateful for a DM.

I killed it. Iciest roads I've ever seen in Evergreen, CO. Slid, overcorrected, and flipped it into a ditch. Crawled out through a window and did the walk of shame back home. It happened about 1/4 mile from my home. I was unharmed other than a few very minor scratches and a slightly sore neck...

I love this thread. I also have a JDM 100 series (also 1998) and have been working through the emissions issues. (Finally sorted after replacing virtually everything involved.) It's inspiring to see what @Sean81 and @JonnyHI are working on.

How would you diagnose on a vehicle with no OBDII link? (JDM)

I have a JDM gray market 100 series (1998, 4.7L V8, 4 speed A/T) with cruise control. Unfortunately, the cruise control is virtually useless in the U.S. because it appears to only allow max speed setting around 50 MPH. Does anyone on MUD know if 1) the JDM cruise control can be adapted or (more...

I'll bet dollars to donuts it's the MAF. I chased down high NOx for Colorado front range emissions from December until now and just passed a couple of weeks ago. (FINALLY!!) Mine is a JDM imported 1998 LC with 70,000 miles and because it's gray market, there's no OBDII connector to run any...

In the past few weeks I’ve been chasing down high NOx, which has caused me to fail emission control three times now. As documented in another thread, I’ve replaced spark plugs that appeared to be original from 1998, cleaned the MAF and throttle body, replaced the cats (so fouled that sounded...

Back to this thread and still chasing high NOx. I pulled the OEM cats and they were clearly perished. They rattled like a set of large maracas full of gravel. I replaced them with new Magnaflow CARB-compliant cats and did notice a little improvement in acceleration up hills. But when I took it...

This would explain my lack of any hits. Thanks

🙌🏼🫡 Thanks much!!

Following up with what feels like a dumb question, but Google searches and review of the FSM and I don't see the EGR referenced for the 100 series. Surely there IS one, and I suspect I can find it lurking near the throttle body. But if anyone has a step-by-step on the 100 series EGR, I'd be...

Thanks for these replies. This weekend I'll clean the MAF and replace the air filter; hadn't checked those yet. I'm also thinking EGR based on the wave values from the emissions report. I've included that image below. From a video I watched last evening, the high NOx readings under...

While this now ranks in my top ten YouTube videos I've ever seen - ranked both in quality of subtitles and general entertainment value - I cannot envision a circumstance in which I would actually do this.

My new-to-me JDM hundo isn't clearing emissions. When I first tested at emissions, I got the following values: HC GPM 0.0903 (state limit is 0.8000) CO GPM 5.7097 (state limit is 15.0000) CO2 GPM 646.6110 NOx GPM 3.443 (state limit is 1.5000) This is what failed me. The vehicle was running a...
