Protege5 dies unless I keep the gas pedal down?!?

[MastaMazda]

My Protege5 has suddenly started dieing as soon as I start it. The weird things is that it will run as long as I press the gas pedal, but dies immediately once I stop. Any ideas?

check intake pipes...
check MAF sensor plug

Check your Vacuum lines and also check your PCV valve & your Emissions control. Just plug your Scanner in under your hood and see what codes you Pull it will tell you right away what is wrong That's the best thing to do !

Idle air control valve...any check engine codes?

 

[MastaMazda]

I was thinking it may be my MAF, but there are no check engines codes coming up, so it's probably not sensor related. PCV valve seems ok (rattles). There were no indications of a problem before it suddenly started dieing. The engine runs smoothly as long as I keep the RPMs above 1000...

Actually come to think of it. I had been getting the P0660 code intermittently before this problem occurred. This may be related.

To add to the symptoms, I warmed the car up to operating temperature and the car no longer dies, but idles extremely low at about 100rpm.

Check your air intake tube. Also p0660 won't make the cel come on so if it has come on its not from that

i was having the same problem until i cleaned the egr valve, installed new intake hose (old one was ripped) and new k&n drop in filter. now it runs smooth.

My intake hose is in good condition. I cleaned the EGR, but no change . Looks like it's time to surrender to the dealer to diagnosis...

no!
I would try giving your car a good Seafoam clean, it can only help

My car began working again after I had it out on the freeway. Perhaps a blockage somewhere, I'm not sure, but my idle is back. Hopefully it's not just an intermittent problem *fingers crossed*.

Sometimes you just need to "blow the cobwebs out" my fianc babies the Mazda when I drive it's slow and sluggish for the first 20 minutes or so

If that was the case, wouldn't it get to the point where electronics don't work, and/or even start at all....

It's possible that the pulley could be seizing up but it would be making a lot of noise. If it runing better since getting on the highway it could have just been a gummed up injector or something I would say to drive it spiritedly for a little bit and see how that goes

My injectors were cleaned earlier this year. Alternator is always putting out between 13.8-14.3 volts.

I would hazard a guess that my idle air control valve was stuck. Probably needs a good cleaning.

I know it has been said before but I would make sure and look closer at your intake tube, the rubber tubing coming from the throttle body to the mass air meter. In the ribbing of the rubber it cracks and will then allow air to get in after the mass air and cause these issues, it is possible it has re seated itself as it the reason you are not noticing any issues at this time. You will want to give it a squeeze to verify it is in good condition as th cracks can be hidden in the ribbing.
