4A-GE MK1 Engine AFM questions

hotwheels · 05-08-2007, 03:37 AM

Ok, so i think my AFM might be bad.
It's still in working order, just not good working order. I'm getting horrible gas milage and running a really rich mixture. I've plugged all existing exhuast leaks, and as far as i can tell, i've got no vacuum leaks. My Idle is also a bit high. about 11-1200 rpms after the engine is warmed up.

I took the AFM out and cleaned it with cleaner, no difference.

I've also heard that adjusting the idle air speed screw is not the best option to do first, because there are many problems that can cause high idle, and jumping to the IAS everytime just covers up existing problems, so i'm leaving that for last.

I dont think the current AfM is worth trying to fix, so i was hoping someone knows of a good aftermarket part that wouldn't suck the pants right off me in an effort to get to my wallet

(horrible analogy, but its the best i can do)

any help?

thanks a bunch!!!

going to any sort of aftermarket maf/map setup costs a decent amount of money...the best thing to do is find a used AFM
