As i said above, you can use an AFM from a mid 80`s cressida with a 5M-GE engine, it uses the same AFM as the 82 supra and its plug and play. Im running one on my 86 4Runner and it was plug and play.

It may be running rich because the previous owner may have turned the little gear inside richining the AFM, just a thought

i dont have a supra afm but i do have the lc engineering intake and its ok but i seen the post about the truck running rich and i think i might be too do you have to adjust your afm when installing an aftermarket intake? mine is still stock and my dad adjusted his on his 3.slow with his s&b intake and he said it made a big difference? just curious before i started to mess around with it

You don`t have to adjust the AFM when installing an after market intake, but if you decide to do it don`t go more the two teeth rich, then drive it and see if you notice a difference.

Rich is loose, turning the adjustment counter clockwise. So to lean it out turn it clockwise.

You can try it 1-2 notches richer (counter clockwise) and see if you notice any gains. Let us know what you notice after doing this.

so i richened it up a bit and it runs better for sure i think the throttle is more responsive and it doesnt miss at low rpms like its starving for air allthough it does miss a bit still at higher rpms on occasion i think im gonna replace my plugs wires and cap and rotor to see if it changes anything hope this helps

yea good idea ill do that too also i have another off topic question ive had 86 88 and 90 toyotas all with 22r/re's in them and now i have an 85 it takes quite a bit longer then usuall for it to actually crank over and start then all my others any ideas what it could be? the only thing i can think of off the top of my head is my 85 has a fuel shut off switch and all my other trucks did not but the fuel pump is connected to the afm so it doesnt seem like it would matter regardless but when its warm the truck starts quick barly one crank... wierd

Your 85 is EFI as well, correct? If so, might try running a multi-meter test on the CSI and if that checks out alright....try the physical test of taking it out. First test it for resistance and also test the CSI time switch. Very often the cause for 'taking longer to start' issues. See, you're having issues when cold...and that could be your Cold Start Injector, which IS NOT uncommonly screwy, lol. Same with the switch. Easy tests to verify/eliminate it from your P.O.E. When warm, everything is under pressure and more easily fired over.

Best wishes,

Mark

Is the 85 a 22RE or 22R (carbed) ?.

Anybody know if this is do-able for a 3.0? and if so, how much size difference is there in the stock MAF and the Supra AFM??

Do a search, someone here swapped a larger AFM on a 3.0, i think the AFM they used came from a camry, but i don`t know if it was plug and play.

CSI = cold start injector. The cold start time switch is located below the throttle body next to the coolant temperature sensor. The thermal time switch can go bad causing the cold start injector not to operate when the engine is cold causing hard starts. Two things you can do that might help your cold start problem are, pull the throttle body and give it a good cleaning, and make sure the vacuum ports arn`t plugged. Next pull the cold start injector and clean it, they get real dirty in the intake.
