Recently, my 2000 Rodeo has started stalling out at random stoplights and stop signs (mostly when I take my foot off the brake to start going again). We put in fuel injection cleaner, cleaned the throttle body, changed all the spark plugs, changed the fuel filter, and changed the pcv valve. Now it runs REALLY well except for the random stalls. Any ideas on what's wrong and/or how to fix it? Thanks!
