Not that big of a deal but, it could be
 

Well i was bored today so i decided to put $10 of regular gas in my car. No problem...i drive to the gas station 3 blocks from my house...i pull out of the gas station.....slow to a light....and as im sitting there....holding the clutch to the floor the car suddenly drops rpms slower and slower...and im just sitting there thinking....wtf?....and it got so low it almost stalled out.....i had to give it some gas but it seems fine now but im realizing that more and more whenever i stop at a light or some place for a long period of time it likes to get REALLY close to just stalling out all together...first thing that comes to mind is....duh your idle got knocked really low or something...or that air meter got stuck open for some reason and its drowning the engine....but....anyone have the same problem? or am i just stupid and thats mazdas way of getting me those 30 mpg. very low idle rpms...

ANOTHER problem i have which IS a serious one is my throw out bearing needs to be replaced asap (so im told)...i can hear it all the time now and ive done enough research to know that throw out bearings are very important.Anyone have any estimates on what this might cost me to get replaced? along with my clutch w/higher performance flywheel?. my car also doesnt like shifting into reverse...i pull up to the side of my house and simply try to back up....and it just wont go in reverse.....i run it through all the gears nice and smoothly and go from 1st to reverse but it just doesnt wanna go.....a FEW times it would go right into reverse with no problem but only after u hear the gears grinding....and the clutch is ALL the way down. My dad informed me just to turn the car off THEN put it in reverse and start it up again. which i hate doing but it works.

sorry for writing so much...just the few small things wrong with my car...but at least i got my new muffler today....DTM style dual 3.5" tips. just gotta run out and get a 2" to 2.5" converter tommorow.

ps- dont even get me started on my oil leak....the trans the engine itself and just about everything from the spark plugs to the dam alternator has oil on it....dont get me wrong i take care of my car but its just to dam cold to spray that thing down and clean it up 100%...the mechanic told me he THINKS its the valve cover gasket which im pretty sure it is...since everytime i pop the hood after a good run i can see glimmering oil in those little knotches where the plugs go....ugh ill have pics soon...havent cleaned it since i bought it....

Maybe you lost clutch pressure...bad master or slave cylinder ???

As for the oil, I'd bet it was the valve gasket too. I have a small leak from mine, makes everything oily, but not that much oil thankfully.

you just HAD to quote, didnt you? :-P
