So I finally got my 7mge afm and put it in and my truck and idled super super low and was on the verge of dying and I could never really get it to idle up.. and if I tried to give it gas it just bogged and didn't like it... I played with the bypass air screw on the afm that you have to drill out and also my idle speed screw on my throttle body and there was no change. I tried it at 5 6 and 7 clicks rich and not much changed. I'm at 14ish degrees advanced timing also. Not sure what else to do, seems like an easy swap over to the people that have done it

 

Any vacuum leaks?? Sounds like it is too rich. Needs more air. Also try this. Pull the efi fuse and wait for 2 minutes then put it back in. This will reset the computer to accept the new AFM. Good luck and post pictures

 

Are you sure you have the plug repinned correct??

All the connections tight.

Remember stepping on the throttle only gives it more air!!

The ECU controls the injector pulse time.

 

You don't have to Repin the connector

 

I was kinda worried that I may have a small vacuum leak somewhere but I will try to pull my efi fuse and see if that does the trick.. and to make it lees rich should I just put the cog at like 3 teeth rich instead of 5 or 6? I have tan flamethrowers by the way

 

3 or 4 teeth should work with the tan injectors.

 

Okay ill give that a try thanks

 

Good luck and report back with the result!

 

Oh yeah forgot to mention I lost the factory settings for the air bypass screw like a dummy, anyone know where that should be set?

 

any updates???

 

Not yet did have a chance mess with it yet, but yesterday I got some v powers and gapped them at .9mm / .036" for my flamethrower coil so those are ready to be put in. I am just trying to get a compression tester from my buddy at the moment because I have never checked my cylinders before

 

I have a same vafm swap mind me asking why you Enriched it? your supose to lean it out i went 3 clicks lean and sit at 14.7-15.2 sweep on my wideband afr gauge. Also how are you likeing your flame thrower injector? Were they worth it?

 

Because the 7mge is set way to lean for the 3vze so you have to make the supra afm richer usually 6 teeth I think and 5 if you have flamethrowers but mine isint getting enough air I don't think. So I'm trying 3 teeth rich. And the injectors are a good bonus, I didn't see THAT much performance gain but fuel milage is better and I heard if you have the supra afm the injectors make a much bigger difference

 

Still haven't got to it sorry guys, I did get the compression tester yesterday afternoon though

 

Didnt get to check all the cylinders because I was in a hurry but the ones I did were just barely below average which is normal considering the milage so hopefully get to that afm this week!

 

Did you find the idle bypass screw setting???

 

Nope never did find the stock setting

 

I think it is 2 1/2 turns from fully closed

 

So should I go more then that out to let it have more air?

 

The last 2 swaps I did the screw did not have to be moved. So i would get it running first and then play with the screw adjustment
