So you can't get it to run at all? Or just not at idle?



Fuel pump?
Fuel pump resistor?

yeah, but i was figuring in prices of stuff... and a zzp "high velocity" throttle body with all sensors only costs 200 bucks... i know they dont really do much performance wise until you are pretty modded but would i be better off getting this? just for the sake of having a new, somewhat better throttle body for less of a price then just the maf...

the price of a new maf is a joke. just buy a used one from morad for a fraction of the price.
