22re megasquirt vs webber vs mafm
So ive had enough of dealing with the afm on my 1994 pickup.
From my reasearch ive come up with three options..
a. Install a webber carb. My worry with that is stalling out on extreme angles, but it is a webber so it should be better than a stock carb? Any experiance or advice would be great..
B. Do a megasquirt pnp system. With the pnp system can i delete my afm or do i need to go with the diypnp to do that?
C. Seems like the pricey option.. lce mafm swap with ecu.. dont really wanna drop that kinda cash..
another option i thought of was putting an aftermarket throttlebody on and making my own intake for it..
any advice or help would be great thanks

Have know idea what you current problems are with AFM.
So standard answer: SAS your truck and pull motor swap to a ........ (whatever motor you like)
Seriously though. Prolly ought to figure out current problem. You might trade out parts only to discover it was a wiring short. Or some other small problem.

For starters the afm is restrictive..
secondly ive swapped a few afms in and out.. first one was good for about a month then i guess it wore out so i played with the origonal one and got some low spots out of it by playing with the brush and strip but still stumbles a bit. One afm stumbles at lower rpm than the other one.. then started stumbling constantly whenever i needed power..
motor swap and sas are in future plans when i can save some cash, i just need it running well right now as its my daily. And if i can get the motor running good i might just rebuild the 22re. Hence why i kinda like the megasquirt idea cause id build the motor up for more power..
i dont want to keep having junkyard afms crappin out on me and for the money of a new afm from toyota id rather take it out and do a stand alone ecu..

What wiring issues could it be?
Truck has around 500k on it.. odo broke 6 years ago at 293miles..
And you cant tell me that the afm doesnt restrict power and efficency.. the air has to push it open.. wouldnt the motor be better off without it?

I'd have to pull a wiring diaghram and visual inspection, hopefully some one who knows more will chime in or point to other potential issues.
The question of AFM restriction on a stock engine has been ran into the ground, just sarch it. My motor is modified with the supra AFM so now the throttle body is most restrictive.

Once some one has it in them something is bad nothing will convince them of anything else.
I never had a problem with any of my AFM`s but were talking of any engine of less the 120 horsepower
Put the same engine in the Celica it was a fun car to drive because of the lighter weight.
To each there own Might find more info over on Celics GTS.Com

Im not 100% convinced.. just seems like the problem when i put a different afm in and the stumble changes rpm..
side note.. i tried checking if its the tps, i see people saying if it runs better unplugged replace it.
Well i unplugged my tps and it wouldnt stay running and wouldnt start again..

You could always go all the way with an Offenhauser intake and Holley 4 barrel carb...

Did a head job a year ago.
New cap, rotor, wires, denso plugs. Fuel pump. Filter..
I took my throttlebody off and it was diiirrrtttyy. Cleaned it up. Found the egr passage was on intake behind tb was plugged so scraped the black crap out and it seems my problem is solved. Truck runs awsome and has more power and better throttle response..

No it stays there.. no matter what i set it at after driving around it goes to 1000. Stays steady there..
it used to surge 1000-1500 when at stop lights and only when foot actually on the brake.. then did tune up swapped afm, ignighter and it was good.
Also. Not sure if its relevant.. but theres a hum in the radio. Always been there since owned. I put an amp in for speakers but still there when i connect ipod to power while playing.. but no hum when not connected..
