Protege sputtering spontaniously
#17
no biggie...just model info...doesntfix his problem...I really think alternator/voltage regulator is the way to go though...my car did EXACTLY what his was doing...took forever to diagnose, as the alt would still pass a bench test with a faulty voltage regulator, I kept thinking it was a vacuum leak....
if you go this route DON'T buy used...buy a new OEM alternator
I just happened to find a good company local that supplied me with a new Mitsubishi alternator(mazda uses Mitsubishi alternators)...car is good as new now !!

Guys,
The car now is doing this ALL the time now. Still when in Park idling or in Drive but fully stopped. Every frigin time the car gets thrown around, RPM needle bounces up and down, sounds like its choking and its gona die, all the lights dim on the dash and radio. I even have to shift into Park at traffic lights just so it won't be as bad. Plus now it takes longer to start the car. Still fine while driving. But i still hear those muffled popping noises comming from inside the intake manifold, still no check engine light.
Dunno if the weather has something to do with it - here it is +4C at the moment, mild and humid. Later the temp is supposed to drop bellow freezing......if its electrical would the moisture make this problem worse?
macdaddyslomo: Are these the same symptoms you got?

I just might do that, prolly going to a friend to have the plugs replaced and he will check it out, than to a shop, prolly dealer one, to get that part replaced. Could it be any of the sensors malfunctioning as well or most likley the alternator? Funny how this problem got progressivley worse over just a week.
Funny though how after I actually get the engine started (after 5 seconds) that it takes maybe 5 mins for the issue to arise as the engine warms up things go to **** and 5 mins in the engine buckles and pops and does all the other wonderful stuff i listed. But why would it do this only in Idle and Drive (stopped) is it because the voltage load is higher when driving so the symptoms don't appear?

if voltage drops it'll throw a CEL. your alternator powers everything electrical in the car and recharges the battery while doing this....when you get up on the rpms it may work a little better but at idle it doesn't have the speed to keep everything powered...thats why it stumbles.

Well went to the dealer.........mech said it was the EGR valve that has seized ( I had it cleaned in Sept 2005), So im gettting a new one and I told him I want the trouble code printouts and the old EGR. I told him to check the alternator too.....so I will see waht happens now.

I hope the guy gives me the comp printout with all the troubles codes. I told him to drive the damn thing for a while to see if it happens again with the new EGR. IT was getting to the point where it was interfeering with normal driving before I brought it in, you could hear that the engine had issues while picking up speed with the popping noises. If this fails than I got screwed out of some serious $$$. Im still betting alternator or 02 sensor, but try telling that to the mech who thinks he knows better, also told him to check for vaccum leaks.
