I was tha one who posted on 5Mpg...i changed my plugs and now im getting 8mpg, and people told me my plug wires were fine and the fuel filter is fine and it shouldnt be tha o2 sensor since people have better mpg even wit tha o2 sensor off( i dont kno how they kno how everything is ok) they sugeested me to clean my fuel injectors...

I was thinking of useing tha Techron Fuel Injection cleaner from Cheveron...Is this good to use??? WIll this help???

Sum people told me to use Motorcycle Vavaline for rotary engines??? is this true???

Please HELP!!!!

 

A: Who told you your plug wires were fine and the fuel filter was fine?

B: Get the injectors professionally cleaned. http://www.cruzinperformance.com/fuelinj.html does a good job for cheap.

 

Sounds like you have a fuel leak. Are you exhaust pipes filled with a black soot?

 

okay, step one: forget about what everyone told you.
step two: you are getting 8 miles to the gallon, something is wrong and you need to replace ****.

SO,
check for a clogged cat.
change yer damn fuel filter anyways if you havn't changed it before.
check and see if your o2 wire is actually plugged up to the harness.
replace your o2 sensor if you havn't already
check for a fuel leak
try the techron stuff first, but sometime in the near future get them cleaned at cruzin.
change your wires anyways
have your coils tested

alot of this is preventive maintenance. you HAVE to do these things.

 

should i bring mine to a local mazda dealer???

I brought it to sum racing auto shop, they said my car was fine and no problems, no leaks and realli smooth and not possible to get 5MPG...so i just drove off

 

I don't see why unless you're really not mechanically inclined. All of the stuff Rupert said is pretty easy to do. Careful with the fuel filter, smoking = bad .

 

NEVER GO TO THE DEALER.

unless you need things like a thermostat etc....

and never go back to that shop. work on your own car. you will learn alot and it's not that difficult, really. just basic tools and some knowledge will get you there

but if you must, go to a good shop, like driver's edge or something.

 

^ Holy ****, who is that in your avatar. That's one nice view.

Lol, i can't read your post w/ that avatar next to it.

how do i check for all those stuff....never did any work under the car b4...i only kno how to do basic tune ups ....( in other words, complete newbie )

 

Nobody has said to do a compression check yet?

 

ofcorse not, we were waiting for you

Rotary_7, pick up a haynes at autozone or something... welcome to the life of a rotary owner.

 

sigh....any one in bay area that can help me out or teach me this stuff???

(scared that 16 year old knowlege will break my car) LOL

 

lol....kool....i forgot all about tha haynes maunal!!!!

It might become my bible!!!!

 

but still...can some one in bay area help me out??

 

its not that hard. just likesir rupert hobo said, just pick up one of those haynes manuals. theyre pretty easy to read and learn from and just take your time. start easy and remember everything you do so if something bad does happen you can come back here and say 'i did blah blah blah to my car and now this and that are happening. help!' and then someone will know what to do. happy motoring!

 

Before I got my car I didn't even know how to do that stuff . Hayne's, FSM, and this forum (and links from it) have told me more than enough of what I've needed to know.

 

o yea.....i dunno iff this will help ...but my car did pass smog

 

I get 9 mpgish right now in town

Just checked out that cruzinperf. place, they use almost the identical ultrasonic machines we have at work... hmmmmmm.

 

Dollars to donuts there is a massive vacume leak most likely around the upper intake manifold...get some carb cleaner and spray all over the seals by your upper and lower intake and your TB I bet your problem lies in there, A new gasket set from autozone at about $30 will pay for itself in a week.
