When I sit at a light or just stop, the idle fluctuates a bit and then just stalls. The car starts up right away and drives fine. What could this be? Fuel filter? Fuel pump? As far as I know, the plugs/wires have never been changed, so perhaps it's time for a tuneup.

Could also be the TB needs to be cleaned... ~TJ~ 97 GL Sport Zetec ~RIP~Connie~1/21/02 ~Mods~ E0 SVT Rims~205/55R16 Goodyear American Eagles~ ~Mods to come~ H&R springs~Konis~Coilovers~17x7 Millie Miglia Avia~215/45R17 S-03's~SVT body kit~98+ OE Spoiler~CAI~Brullen Cat-Back~Turbo (or 2):)~ More to come

It has stalled as I roll to a stop about half a dozen time. Alarmingly, it also stalled as I was downshifting (not fast enough, it seems) before a slow (~20 mph) corner with traffic behind me. luckily, I was able to get it restarted before I got rear ended. I haven't had a chance to replace the O2 sensor yet, and I'm sure my TB is very dirty - I rev the engine to within 500 rpm of redline daily.

Turned out that it was the IAC motor, not the O2 sensor. Since Mazda parts are ludicrously priced, I traded it in for my 'tour, which pulls the same crap at 60K... on rare occasions, fortunately.

I dropped it off at my mechanic so I'll find out soon enough. Hopefully that's it. The problem just sprang up out of nowhere. And as I mentioned, it runs just fine when the gears are engaged (manual tranny). Pardon my ignorance, but what is "TB"?
