I would start your own thread and post up your test results.
You will probably get a better response.
Running rich doesn't tell much.

I just tried to get it smogged after sitting for 2 years and replacing these parts little by little, and it failed smog in California. Guy didn't charge me but said it was running too rich. Any ideas? Do I need to pull the EFI fuse since I replaced the injectors? I read about changing the mixture with some turns and clicks? Can anyone give me an idea of what I can do. Thanks!

you need to get inside maf by removing plastic top which is silconed down. Inside is a cogged wheel and spring. Think you turn cogged wheel 2 clicks anti clockwise. There should be a write up on the tuning section under supra maf. Very simple to do once inside. Will see if i can dig out photo for direction of turning cogged wheel.

Start by scanning your report and posting it. "guy said ..." is a little too vague. Or, you can research it yourself here: http://www.cygnusx1.net/Media/Supra/...taTech/h55.pdf

".. changing the mixture with some turns and clicks" probably refers to hapless messing with the VAF. That won't help you at all in closed-loop, which is the only place you're tested.

You DO need to re-learn fuel trim, but you only need to drive it for 10 miles or so. You don't need to pull any fuses.

I assume, of course, that your CEL is working and you have no codes. If not, you SHOULD have failed for that alone.

If the Toyota engineers wanted you to remove your "OEM VAF" lid they would have put fasteners on it, that's why its a sealed unit.
This might be the norm for a Supra MAF, mod, but the individual failed smog in "California". and I don't see where he did a Supra Mod.
As scope103 mentioned turns and clicks probably will result in more "hapless messing with the VAF"
He needs to start a new thread with his smog test results in order to have a starting point.

Hey guys, it turned out to just be the O2 sensor. Replaced it and it passed by a mile.

I wasn't sure if it had to do with the new Flamethrower Injectors and the 8% more fuel.

Appreciate all the help!
