Ok I have a 1990 toyota pickup with a 22re, well i had the brught idea to mess with the air flow meter and when I did I lost the stock position. Is there anyway I can get it back to there? My pickup like bogs out when you press the throttle then it back fires which I don't think is real good for a EFI!!! Please help me figure this out or let me know where I can order a new air flow meter?

Thanks Bruce

So in other words....You didnt mark the location before you messed with it.or did you let it slip ,thus have no idea how many teeth you moved it.

I had a mechanic friend mess with mine and it never ran the same untill I got a new one. It had no power and wouldn't idle. I really don't think there is any way to get the setting back. I bought my replacement at a junk yard for $150 and they sell at a dealership for $500.

When I was working at an independant shop, they had a tool to measure the spring tension to reset it to stock. That shop (and the tool) is out of business and gone.

I bought a spare for my son's truck for $15 form EBAY (85 22RE)

Did you move the retainer and have it jump a bunch of teeth or have you just been moving it back and forth and lost the original position?
If it jumped a bunch, you're basically screwed unless you can find out what the factory spring tension is supposed to be and then come up with a way to measure it.
If you've only moved it a little, you can run the truck with the afm open and adjust the wheel while the vehicle is running. A quick look at the tailpipe should tell you if you are running rich and you can work it to lean out the mix. After you think you have it close, button it up, pull the EFI fuse or the negative terminal on the battery for 5-10 minutes and let the ECU reset then take the truck for a drive. It can take a little driving while the ECU relearns what it needs to do so you may have to repeat this a few times.
Ebay is probably the best bet. Stuff seems to go pretty cheap there.
And personally, I would say PARK THE TRUCK! You are either running way too rich or way to lean and both can lead to serious engine damage.
Keep in mind also that if you are in an emissions controlled area the factory seal being cut on the afm would, I believe, result in failure to pass inspection and may even be illegal. I don't live in an emission area so details escape me, but check and make sure where you are.
Lastly, unless you have done some serious mods on the engine, messing with the afm will really only result in trouble of some kind IMO.
