Q: rough idle and stalling when stopped on 2002 Isuzu Trooper

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Every once in a while my trooper ( fuel injected 2002 ) will rough idle when stopped or in park then engin stalls. It restarts right away but then stalls again. It stays running after several attempts at restart when revved to 2500 - 3000 rpm for a few seconds therafter. I've had tune up - belts, o2 sensor, plugs, oil, and fuel / air filter changed but problem persist. What should I try next?

I had a similar problem on the same vehicle. It was caused by a tiny vacuum leak. You can do a smoke test to verify. Replaced intake manifold gasket. Problem solved.
