symptoms of running rich?
 

since I got my TPS taken care of, the car has been running pretty well, no noticable hesitations, no stalling...... I havnt really payed attention to the gas gauge, but it seems like I burned through alot of gas this week, with average driving... etc...

what are the sympotms of running rich? I have no black smoke, the exhaust doesnt smell like unburned fuel, just smoggy, but I get that with having no cats...

I dunno if its related, but when I crank her up, I hear a rattle, before the idle set9tles down to 900rpm... dunno, if thats something inthe exhaust? I dont really hear any tap tap tap tap like an exhaust leak would sound...
