my engine sounds like a table saw
 

when I start it up , for a minute or so then the sound goes away WTF

a sound clip would help

It's the air pump. No big deal.

airpump going out.

airpump going out - I had the engine check light on and lack of power this morning. This happened yesterday for a while, then it was fine the rest of the day, then this morning it's happening agai

found a youtube video. that's exactly what it is. could it be causing the performance issues the car is having?

not really since it only turns on momentarily when the cat is warming up and shuts off most of the time.

Nope. The air pump has exactly zero affect on performance.

nothing to do with the check engine light flashing and lack of power,, which just goes away for no reason.

check engine light flashing means you have misfire. check (replace) coils and spark plugs.

As usual, jason gives sound advice. :-)

As for the air pump, it can set a check engine light, but not until it seizes up and causes the air pump fuse to blow... And then it will set a solid check engine light, not a flashing one.

coils and spark plugs - how about wires too....

are coils easy enough to replace?

Yeah... http://tinyurl.com/3c2o6pv

^Thank you for posting that! This was getting unbearable lol

I learned it by watching you!

(Quote from an old 1980's television anti-pot PSA, for all you youngsters.)

oh your all so funny ;-)....sorry trying to work and figure out my car issues at the same time. so call 3 different parts stores today they each have one coil. who has one coil when 4 are needed.
maybe i can call a 4th store and find one there too.

just order online. dont mix match coils.

I gotta do something quick barely made it home from work....taking tomorrow off hopefully can find the parts, maybe the local mazda dealer will have em,

Ouch, don't do that... A Mazda dealership will completely rip you off.

You can get plugs at Autozone/Kragen for $80

Coils you really should buy online from someone reputable, maybe even take this time to upgrade to the BHR coils?

where you from, maiter?

they ripped me off. I just don't have the time or energy for this. I can't even stand to tell you what they charged me, although I am going back next week to get the cat replaced under the extended warranty. it's running really well right now anyway.
they tried to get me to do the motor mounts, I said why , I'm not noticing any untoward vibrations...

Thank you so much for the post. It's really useful.

Are you sure that table saws don't sound like your engine?

This is a valid point, Got to look at the situation both ways.
