My Mazda Tribute 3.0 v6 MY2001 with 170000 km, starts fine in mornings ( 10 celsius ) with fast idle for a few seconds, then idle drops below 1000 rpm and in the warming up period, about half way to working temperature, idle become rough and lower than 500 rpm, engine almost stopping so we have to apply some throttle. When engine reach the temperature, idle become nice, stabile and steady. Recently we have heard some buzzing from fuel pump but it had stopped atfer few days New spark plugs are in, idle controler is cleaned, new air filter, MAF sensor cleaned..... What can be a problem ? Thanks

Don't waste your time.
Have the intake manifold gaskets (upper and lower) replaced.
Check all vacuum lines for leaks.
Clamp all vacuum hose connections.
Do NOT replace any sensors unless the computer codes indicate.
THIS WILL FIX YOUR PROBLEM!

Try unhooking one of the battery cables and leave it off for at least 20 minutes. When you hook it back up the computers should re-boot. That has solved problems for me with heater, interior lites, power windows, AC, day time running lites, power mirrors, fast idle, rough or slow shifting, CD player, and wipers on GM autos and S-10 PU and Dodge trucks. None of the switches are connected to the device they control anymore. The switch tells the computer to open the window and the computer send a signal to the window motor. When the computer gets confused strange things will happen or not happen. Of course you may have to re-set your radio stations.
