1998 Isuzu Trooper 3.5L, V-6 mileage: 62,000. After cruising 100+ miles on the highway using the cruise control, I slow down at a traffic light and the car stalls. It restarts without problem but the idle is poor and sometimes quits. This morning the car started great, but after I came out of the store and restarted, it would not idle unless I pump the gas or maintained RPM\'s above 1000. Made it home and checked all hoses and connections and started ok with good idle. Is this an IAC valve problem?

Your problem may be an IAC (idle air control) valve. Also, check for a faulty EGR (exhaust gas recycling) valve that may be sticking open.
