I've tried it before, and there was no difference in the fuel trims afterwards. I have used the "reset idle" and "reset fuel gauge readings" before, and they both worked, so I wonder why the "reset adaptations" didn't work as well?

What are you using to track the fuel trims? I noticed that the foxwell wouldn't show me the realtime fuel trims like dash command on iphone did

Go to ODBII scanning. Read codes. No codes will show unless the SES light is on. Clear the codes. Even if none are present. All emission data will clear. Yes, over time, fuel will be adjusted. Starting fresh will give new MAF data. Once all emissions are set/passed, you’ll know if the new sensor is successful. Or it will show a problem still exists.

Thanks, I'll try it

Do you mean the OBD2 selection on the bi-directional Foxwell? and would my Innova 3100i scan tool (not b-directional) be able to clear emissions data, even if no codes are present? It never occurred to me to "clear" non-existent DTC's.

Yes. A standard scanner with ODBII or Foxwell will clear DME emissions data. Welcome to Kali or major metro OBDII emissions testing. I get calls all time when cars won’t pass emissions testing in Austin. Only diesel vehicles can pass inspection with an SES light on. Only with a few exceptions. A sensor replacement like MAF, O2, MAP, and EGR require reset or data clearing. The DME will run emission tests. When all test pass, the engine is within operating parameters.

OBDII code clearing will not clear adaptations.

blew out the vents in the sunroof. The driver side seemed blocked, now have good flow on both sides. I'll try the car wash again soon to see if that is enough.

One thing I noticed after fiddling around with the sunroof is that it has a tilt setting too :) (not bad after owning it for 2 years). There's a plastic drip tray in the back that was loose on one side. I snapped it into the post, but after going back and forth it came loose again on one side. Anyone has any experience with this?

He only needs to clear emissions. Adaptations are for wear and tear. The Foxwell will do this.

Interesting, mine has been trouble free for 20 yrs...broken plastic clip/fastner of some sort? Hope I didn't just jinx myself. Be careful with blowing the drains out as the rubber drain lines simply stretch over a tapered/knurled nipple on the sunroof tray. Its just a friction fit, which I can see popping off with compressed air into a restricted tube.

I've heard of guys snaking them with weedeater line.

Since my headliner pan was out this week I pulled each tube and made sure they were clear (blew thru them), then re-secured them to the nipples. The A pillar covers come off pretty easily.

I thought we were talking about resetting LTFTs? That's part of adaptations, not an OBDII clearing last I checked.
